Our Approach

How we analyzed the best Yoga Mats

Functionality
We assessed each mat’s traction under both wet and dry conditions, as well as their thickness, weight, and comfort.
Eco-friendliness
We took note of the material used to make the mats and how much of an impact it had on the environment and health of the practitioner. We sent samples of each mat to the Ecology Center in Ann Arbor, MI to test for any toxicity.
Value
We set out to find great mats at every price point; however, high-quality eco-friendly mats under $40 were hard to find. We decided to assess the value of the mat instead, that is, whether their durability and features were worth the price.
Design
We assessed how well-designed each mat was in terms of sturdiness, how easy they were to clean, whether they absorbed sweat, among other factors.

Infographic Yoga Mats in a Nutshell

Updated Information on Eco-Friendly Yoga Mats

When we first published this content, we were still pending the results from samples we’d sent to the Ecology Center, a nonprofit focused on researching toxic chemicals in everyday products. 

As we wrote below, almost half of all yoga mats are made from Polyvinyl Chloride (PVC), a substance that presents a number of problems - from the pollution it creates during manufacture and the risks its chemical additives can present, to the harmful effects its incineration can have in countries and states where trash is burned. This is why we decided to not include any PVC mats in our list, not even making an exception for Manduka’s PRO line, one of the most well-regarded mats in the world. 

We focused instead on natural materials and some synthetic ones - polyurethane, PER, and TPE - that were described as eco-friendly alternatives to PVC. These materials were marketed as biodegradable, recyclable, and non-toxic. While our preliminary research showed some gaps in information about how exactly some of these materials were made, we trusted that manufacturers’ claims about their mats would probably hold true. 

But then the lab results came back. Needless to say, we were surprised to find out that despite our careful research and manufacturer’s claims, some of our supposedly eco-friendly mats were decidedly not what they claimed to be.

 

Why your yoga mat matters

Yoga was practiced for a long, long time without the mats we have now. So why is a mat so important?

For one, yoga is much different now than it was when it started thousands of years ago in India. Practicing yogis emphasized yogic breathing (pranayama) and meditative techniques much more than the calisthenic type of yoga we do now.

And so, as yoga kept evolving, the means to practice it did too. Practitioners in India were known to use dead tiger skins (presumably of those who died from natural causes) and deer skins to practice on. Later, they turned to clothes or towels.

It wasn’t until the 1970s, when a yoga teacher named Angela Farmer brought a piece of carpet backing to a class so she could practice without slipping, that interest in “sticky” yoga mats really picked up. However, these “carpet backing” mats, while they offered traction, didn’t hold up for long under vigorous practice.

In the 1980s, Sarah Chambers of the yoga products manufacturer Hugger Mugger, designed and introduced the first sticky, durable rubber mat specifically meant for yoga.

Today, there's a yoga mat for every need, body type, yoga style, and aesthetic. So, how do you choose the best mat for you?

We have a few ideas.

Our Top Picks: Yoga Mats Reviews

Suga review

*Update: The Ecology Center found unspecified phthalates, which they call “chemicals of concern” in their analysis of the Suga Mat, so we contacted Suga to discuss how they test their mats for this type of chemicals. Brian Shields, CEO of Suga, told us that they have their materials tested at a lab in their factory and found their mats to be negative for phthalates. Additionally, they’ve found that “the leaching potential of any chemical has been studied at length and has been repeatedly found to be completely inert (non-reactive).”  Shields told us that the mat we bought might not be representative of the ones they currently produce, and decided to pursue further testing of this mat and others to ensure the safety of their materials. We will keep updating this section as we receive results. 

  • Material: Recycled Wetsuits (Neoprene)

  • Lab Test Results: Styrene-butadiene rubber, polyurethane, polyester (PET), unspecified phthalate (pending results)

  • Price: $79 ($99 for its lifetime-guaranteed option)

  • 100% of our in-house testers would recommend this mat and/or buy it for themselves

  • Types of yoga: Vinyasa, Bikram/Hot Yoga, Ashtanga, Restorative/Yin

  • Good for: Almost everyone, although people with very sensitive joints might prefer a thicker mat.

“I'm probably going to buy this mat for myself and would recommend it to other people. I love the material, the look, the feel ... and overall think it's a great, versatile mat. By far my favorite.”

“I think it had the perfect amount of thickness and squishy give. Almost like memory foam. Out of all the mats I've tested, this one caused me no pain. I could stand long planks and downward facing dog a lot longer than I have in years so I was really pleased.”

“Goodness, this mat was easy to clean! Simply brushing it with my hand was enough to get cat hairs off it. I really like the fact that it has closed cells which make it harder for dirt to get in, too.”

“I want this mat to live with me. I love that it looks like a homemade paper project from middle school, love its width and lack of stickiness, and how it's extra-long.”

“It looks cool, it feels cool, and it’s good for the planet. I also love that they have a mat that gives back: 10% of proceeds from the sale of one of their mats (the blue mat) goes to a nonprofit partner.”

Our Testers' Favorite Mat

Our in-house testers included experienced yogis and complete beginners; some who are workout fiends and others who prefer a more leisurely pace, but there was one thing we all agreed on: we all love the Suga Mat.

Made from recycled wetsuits, the Suga Mat combines many of the very best features of other mats and takes them one step further.

Many mats that offer great grip do so at the expense of cleanliness - those mats’ open-cell design often provides great traction, but makes them very hard to clean. Suga offers the grip of those mats but with a closed cell design that makes it a breeze to maintain. Our testers found it easy to wipe away any sweat or debris, and those of us who are pet owners, found that removing pet hair didn’t take much effort at all.

In fact, the company says that you can hose it down and even shower with it, as long as you hang it in the shade. While we didn’t go to that extreme, we did find it easy to wipe down and clean. The company says that they add an organic antimicrobial solution to the wetsuits they use for the mats, which could theoretically protect it from many types of bacteria, fungi, and viruses.

The Suga Mat’s density also provided great cushioning, but with just enough give for those with injured joints to practice comfortably.

Like many other mat manufacturers, Suga offers a 30-day guarantee on their mats. Like others as well, this only applies as long as the problem was not a result of owner negligence. However, Suga does something unique: they encourage consumers to send back their mat - even if they were to break down due to something the owner did - so they can recycle it into a new mat.

They also offer what they call a “Cradle to Grave” option under which, for an additional $20, they guarantee you a mat for life. This means that if your Suga wears down, you can send it back, and they will replace it with a new mat.

The company also partners with the non-profit 1% For the Planet, donating part of its proceeds to its non-profit partner, Sustainable Surf.

Brian Shields, chief executive at Suga, told us (via email) that the mats are made at a family-run facility and that they pay their floor workers “well above the minimum wage”. The facility, he said, is also run on 100% green energy and recycles any scraps into future production. Additionally, they use Verified Carbon Standard (VCS) carbon offset to negate the carbon footprint caused by shipping and production. 

While we love Suga’s commitment to the environment, they would not be our “testers’ favorite” unless their product was something uniquely wonderful. Fortunately, it is.

Most Eco-Friendly Mat

“This mat is super low-maintenance and I like that it has markers on its surface, it makes it easier to align in poses like Warrior I & II.”

“I would definitely recommend this mat! It exceeded my expectations. Its versatility makes it work for everyone --either to take to the gym or a yoga class. I want it myself.”

“I would recommend this mat for someone looking for an eco-friendly option that's easy to clean and won't get germy.”

“It had the perfect thickness. It supported my joints well and it was comfortable, as well as it was easy to hold my balance on it. It was very easy to roll back up, but it was a heavy mat to carry around.”

Cork, one of the most eco-friendly materials on the planet (see our Materials section for more information), is not only good for wine, it’s also an amazing material for yoga mats.

The Tranquility Essential’s base is made from natural rubber, the cork top gives it a smooth, natural surface that still provides great traction, especially when wet. Its lotus flower design with lines reaching out the sides is not only beautiful, it also serves as a guide to proper alignment.

While other mats have a distinct rubbery smell that can take months to fade away (which can be off-putting when you have to place your face on the mat), our testers agreed that the Tranquility mat had very little odor and, if anything, smelled pleasantly earthy.

Our testers also praised the mat’s thickness (we tried the 5mm mat) and how comfortable it was. Its density, however, can have its drawbacks. For example, one of our testers - who has a joint injury - said that the mat didn’t have enough give for her joints, making it hard for her to practice.

The other drawback comes from how heavy it is to carry. At 6 lbs, it was the second heaviest of the mats we found; it did however, come with carrying straps, which is a big plus.

Tranquility Essentials is made by Canada-based Tranquil Yogi, which makes a wide array of yoga gear in biodegradable materials, mostly natural rubber and cork. The company states that a portion of its profits are donated to support “the Yoga community”, by running community classes, workshops, and giving scholarships for teacher training, among other things.

Tranquil Yogi offers a 30-day guarantee on their products. Their website states that they do not pay shipping costs for returns which, since the company is based in Canada, could be a costly shipment to make from the U.S. However, a representative for the company said that, while the official policy is that customers have to pay for shipping on returns, "in practice, they generally ship out a replacement no questions asked", and that consumers should contact them if they have any issues. 

We found that Tranquility Essentials mat offered a long list of positives that more than outweigh any negatives: beautiful, easy to clean, comfortable, and last but certainly not least, good for the planet.

Liforme review

  • Materials: Natural rubber and their own proprietary polyurethane
  • Lab Results: Polyisoprene (natural rubber), calcium carbonate, polyetherurethane

  • Price: $140.00

  • Testers praised its alignment lines, cushioning, and excellent grip

  • Types of yoga: All types of yoga, especially Iyengar (emphasis on alignment)

  • Good for: Joint and balance issues, beginners

Best For Yoga Therapy

“Love the guidelines. Easy to roll up. Loved the carrying case. You can tell this is a luxury mat.”

“I loved the feel and practicality of this mat. The lines make it easier for less experienced yogis like me to keep up with their instructor, the case makes it a breeze to transport, and the material has enough traction to keep you in place during inversions.”

“Loved the thickness! Balancing was a joy on this mat.”

At $140, Liforme is definitely an expensive mat. And once we tested it, we realized why. It is a patently well-made product, satisfyingly solid, with just the right amount of cushioning to protect your joints, while still giving enough traction to hold onto even the most challenging balance poses.

Its unique alignment guide (a pattern of lines etched on the surface) proved to be very helpful for both novice and experienced yogis, but should be particularly so for those who practice Iyengar yoga, who have to pay special attention to alignment.

Liforme has also gone to great lengths to ensure the safety of their mats. In 2017, they commissioned a study to test their own brand of polyurethane, which found that it was safe for use and that the material itself would biodegrade in one to five years under normal landfill conditions. The alignment guides drawn on the mats are etched, not printed, to avoid toxic inks. They also use a unique heat-bonding process to avoid toxic glues in binding the rubber base to the polyurethane top.

It does have a few drawbacks. First among them: the smell. While Liforme comes in a great carrying case, the overwhelming sentiment from our testers is that it smelled like a fish market when we opened the bag. This has subsided somewhat after a month of use, but not completely. This might be due to the closed carrying case itself, which doesn’t give the mat the aeration it should have.

Secondly, it is heavy. At 6.5 lbs, it was easily our heaviest mat. Because it has such a great carrying case, it was easier to transport than it otherwise would be; however, this mat would work best as one to practice with at home, not necessarily carry to a studio.

Lastly, Liforme provides the shortest return window of all the manufacturers we reviewed- only 14 days - and does not provide a warranty for their products. In order to return the product, it must not have been “handled or used” and has to be returned with all original packaging intact.

The company will not specify how long their mats are likely to last, saying that they balance durability with eco-friendliness and that their mats are likely to wear out over time. While that’s definitely understandable, consumers will still need to know that their investment in such an expensive mat will pay off, and that they have the ability to exchange it if it’s not right for them or if it has a manufacturing defect.

However, our testers almost uniformly praised the Liforme (in fact, one of our testers ended up buying one for herself), and would recommend for both experienced and new yogis alike. It could be a great choice for those using yoga to recover from injuries, due to its cushioning, grip, and helpful alignment lines.

Manduka eKo Lite review

Best for Travelers (and Pet Owners)

“This feels like a luxury mat; it felt great, smooth, sturdy.”

“Very easy to clean, completely repels water.”

“Felt very sturdy, I feel I could throw it against the wall and it wouldn’t suffer major damage.”

“Not a good grip though. Really slippery compared to every other mat I tested.”

There’s no doubt about it, Manduka makes some of the highest quality mats out there. Its top-of-the-line --the Manduka PRO-- is perhaps the most popular yoga mat in the world, used by millions of yoga teachers and students around the world. This PRO mat, however, is made from PVC. As we stated above, we chose not to include mats made from this material because of the highly polluting nature of its manufacturing, and the damage it can cause to the environment. Manduka states on their website that, while their mats are made from PVC, they’re made in factories that are certified emissions-free and do not contain harmful plasticizers. However, they also acknowledge that PVC is not an eco-friendly material.

Because of this, we chose to try Manduka’s eKO Lite, part of its “greener” line of mats made from natural rubber. The eKO Lite garnered praise from our testers, with many finding that it provided the cushioning and sturdiness of a high-quality mat, while still being light enough to take along on your next trip. The smooth, firm surface repels dirt, hair, and water, making it easy to clean. In fact, testers with pets found that cat and dog fur were easily wiped away from the surface, which also stayed intact even after one reviewer’s dog vigorously chased its tail on it. On the con side, its smooth surface does not offer much grip, especially when wet (as stated above, it completely repels water, which makes it slippery). While this would not be our first choice to take to a hot yoga or Ashtanga class--unless you use a grippy towel or yoga gloves--it’s a great everyday mat that’s easy to take with you wherever you go, including the beach. (Yup, we tried that too.) 

Jade Level One review

  • Lab Results: Polyisoprene (natural rubber), kaolin, bis(2-hydroxyethyl) tallow amine, zinc stearate

  • Price: $39.95

Best Budget Mat

“Felt durable and was comfortable even after sitting on it for 2+ hours.”

“Super grippy, no issues at all with sliding.”

“Extremely sticky. This was a great feature if I were doing hot yoga, but ended up collecting dust and dirt quickly.  This mat is not recommended for outdoor use.”

At $39.95, Jade Level 1 is one of the most budget-friendly of the eco-conscious mats we tested, and one of our reviewer’s favorites. Our testers praised the mat’s excellent traction and feel. It was also much easier to clean than its more expensive cousin, the Jade Harmony, which we also reviewed. However, this might not be the right mat for those with sensitive joints, and its thinness makes us wonder whether it can withstand vigorous, long-time use. Additionally, although its lightness would make it a great travel mat, outdoor use would require special care, as dirt and dust easily cling to it. However, yogis who like their mats with extra grip--and don’t mind having to clean it often--could find this might be the mat for them. 

Lululemon The Reversible Mat review

  • Materials advertised: Polyurethane

  • Lab Results: Polyetherurethane, polyisoprene (natural rubber), calcium carbonate

  • Price: $68

  • Allergy warning: Latex

Screenshot lululemon.com, August 6, 2019.

“It felt well-made and firm and stayed flat at the ends, although some denting can occur and it doesn't seem to bounce back quickly.”

“It had GREAT grip, definitely did not have to make an effort to stay steady.”

“It's super tough to clean, because it absorbs water and sweat. I don't want to have to clean my mat everytime I do yoga (if it's daily, it would be a nightmare), but this one feels like I would have to wash every day.”

Given that the name Lululemon might be synonymous with expensive yoga wear, we were surprised to find that its yoga mats are actually reasonably priced, at least when compared to other high-quality, non-PVC mats. As its name suggests, both sides of the mat are appropriate for use--one side with more grip than the other--making the mat versatile and appropriate for different preferences and practice styles. The side with more traction is exceptionally grippy, even for those who practiced hot yoga. 

Although the mat is 5 mm thick - a fairly standard level of thickness as far as these mats are concerned - testers with sensitive joints noted that it’s not dense or firm enough to protect their knees and wrists in positions like plank or kneeling lunges. This lack of firmness became even more noticeable after two weeks of consistent use. The other most frequently cited drawback involved the mat’s cleanliness. 

While the mat has great grip, it also absorbs dirt and sweat and stains which proved very hard to clean.

However, for those with strong joints and who don’t mind taking a little extra care of their mat to keep it germ-free, this could be the right choice at an affordable price. 

Aurorae Synergy 2-in-1 review

  • Materials advertised: Polymer Environmental Resin

  • Lab Results: PVC, DOTP

  • Price: $59.95

Screenshot auroraeyoga.com, August 6, 2019.

“The mat is fairly well made. It rolled out flat, which is a plus, but denting was an issue to the point I had to keep moving up and down the mat.”  

“Comfortable, soothing, but too thin for joints.”

“When wet, it has much more grip. It was like using a different mat. This is definitely one of those that is best to use when sweaty.”

The Aurorae Synergy 2-in-1 is one of the two mats we tested that were advertised as being made from Polymer Environmental Resin (PER). On Aurorae’s website, it states that their mats are “considered eco-friendly” and that “our patented PER is not PVC as many less expensive yoga mats and products.”

However, as we said above in our summary of the testing conducted, our lab determined this mat contained PVC. Both Aurorae and Lansong Industries--manufacturers of the material--stressed that their material was safe, biodegradable, and that it obtained Oeko-TEX certification (a global testing agency that certifies textiles as toxin-free). However, the lack of harmful additives in their mats does not take away the polluting aspects of PVC manufacture and disposal, making it difficult to justify labeling it eco-friendly.

The mat itself had mixed reviews from our testers. Some found it too thin for their joints, but many praised the microfiber top, saying it felt soothing and comfortable. The microfiber top also presents some drawbacks though, as it was difficult to clean without a lint roller and its absorption of sweat will require careful washing so it doesn’t become a breeding ground for bacteria.

While the Aurorae doesn’t offer much grip and tends to slip on the floor, testers found that the grip improved with moisture, making it more appropriate for hot yoga or for those who sweat during their practice. 

Overall, the Aurorae Synergy has its place as a good travel mat for those whose joints don’t mind a thinner mat. However, we question the use of “eco-friendly” or biodegradable to describe these mats when the suppliers themselves acknowledge that it’s made from PVC.

Ajna Jute Wellbeing review

  • Materials advertised: Polymer Environmental Resin (PER)

  • Lab Results: PVC, DOTP

  • Price: $56.98

Screenshot ajnawellbeing.com, August 6, 2019.

“The mat felt sturdy and well made but it also felt thin and wasn't comfy on my joints.”

“Too thin for me. I had problems kneeling on it and also during savasana.”

“It just wasn't comfortable to practice on. People who sweat a lot definitely shouldn't invest in this mat. Anybody with sensitive skin should also stay away.”

“No. Didn't like the smell and the feel. The grip was unstable and honestly, the chemical smell was a huge turnoff for me. Also, I scraped my knee because the surface is so rough.” 

From planting a tree for every mat sold to including seeded cards customers can grow at home, Ajna Wellbeing’s brand is centered around the eco-friendliness of their products. The Ajna jute mat is a good example, advertised as being 100% biodegradable and recyclable, made from jute and Polymer Environmental Resin. On their website, Ajna describes their mat’s materials as an “eco-synthetic rubber, free from PVC, heavy metals, formaldehyde, phthalates, phenols, PAH’s, latex, rubber, or silicone.” 

But, just like the other PER mat we reviewed (Aurorae Synergy), our lab partners determined that this mat was actually made from PVC. We attempted to contact Ajna’s representatives several times, across different platforms, but have yet to receive a response. We will update this if and when they do. It’s worth reiterating, however, that Lansong Industries, the company that claims to have the patent on PER, acknowledged that they use PVC in making their material.

As to the mat itself--our in-house testers gave the mat fairly poor reviews, describing the texture as being too rough on their hands and knees. Despite this rough texture, the bottom surface remained slippery on the floor, leading volunteers to struggle to stay in place during vigorous practices. Those with sensitive joints didn’t fare well either, as the thinness of the mat did not do much to protect them. Finally, a little piece of the backing came off after two sessions, which doesn’t make us confident about its durability.

Jade Harmony review

  • Materials advertised: Natural Rubber

  • Lab Results: Kaolin, bis(2-hydroxyethyl) tallow amine, zinc stearate, polyisoprene (natural rubber)

  • Price: $79.95

  • Allergy warning: Latex. 

Screenshot jadeyoga.com, August 6, 2019.

“Awesome grip. I felt super steady and centered. It really helped me enjoy my poses and stretch and go deep.”

“The weight and feel of the mat are great, but it's still very thin. I'd use it as a topper mat with a thicker one underneath.”

“It collects a lot of hair and dust and it's so grippy that paper towels will leave little particles behind after wiping.”

For yogis who sweat and/or just like extra grip on their mats, it’d be hard to top the Jade Harmony.  It is, by far, the “grippiest” mat we tested. Its open-cell design and ridges give it unparalleled traction, making balancing poses and inversions a little less difficult.

Slightly thicker and sturdier than the Jade Level One (which we picked as our best budget mat), the Harmony mat provides more cushioning and protection for the joints. However, at 3/16,” the Harmony might still be too thin for those with very sensitive joints. 

Unlike most mats on the market, Jade mats are made in the United States. They are also made with natural rubber, a renewable, sustainable resource. It’s important to note that, as with other products made from natural rubber, people with latex allergies should not use this mat. Further adding to their earth-friendly credentials, Jade also says they plant a tree for every mat sold. 

However, the Harmony does present a serious drawback: a reported lack of durability. An analysis of customer reviews across the web shows a pattern of complaints claiming that the mat’s rubber started breaking down in as little as three months. Given that natural rubber can break down in sunlight, special care might be needed for mats made from this material. 

ISHA review

  • Materials advertised: Thermoplastic elastomer (TPE)

  • Lab Results: Ethylene/vinyl acetate copolymer, calcium carbonate

  • Price: $36

Screenshot ishashoppe.com, August 6, 2019.

“I was able to complete my practice, but the balance poses were difficult due to the mat being too cushiony.”

“The dry grip was pretty low. I slid during downward dog and other poses.” 

“I really like this mat because although it is lightweight, It was surprisingly thick. Felt so good on my joints and it was super easy to roll up/carry.”

Made from a material called TPE, the ISHA mat is a very reasonably priced alternative in the eco-friendly arena and, at 1/4'', the thickest mat we tested. This thickness is both a pro and a con. While some testers with sensitive joints enjoyed the cushioning it provided, other testers found that balance poses were extremely challenging to hold. 

Additionally, while the mat is thick, it doesn’t have the density required to truly keep its shape long-term, especially if used daily. After two weeks of consistent use, the model in our office started losing its firmness (making it harder to roll up) and the surface had torn slightly by the fourth day.

However, for those who don’t plan on using it daily and can give it careful maintenance, the ISHA can certainly be a good option, especially if you have joint issues or love the long poses involved in restorative yoga. As a bonus, it can also serve as a comfortable exercise mat, and our volunteers who tried Pilates and ab exercises on the ISHA gave it rave reviews. 

Yogasana review

  • Materials advertised: Cotton

  • Lab Results: Not tested

  • Price: $95.00

Screenshot yogasanamats.com, August 6, 2019.

Handmade by master weavers in India, the Yogasana mat is as beautiful as it is earth-friendly. Each mat is made in a loom, without the use of electricity, and signed by the weaver that made them. The company also says that the mats’ vibrant colors come from non-toxic dyes and that they have installed a treatment facility where “dye water is treated before being used for irrigation of vegetable fields”. 

All this, in addition to the fact that natural fabrics are said to be ideal for yoga practice, made us really, really want to love this mat. Unfortunately, the Yogasana did not work for us. Volunteers complained of chafed hands, feet, and knees because of the mat’s rough woven texture. When we tried to wash it to soften it -- as the manufacturer says you should do -- the drying process took about 48 hours and it still wasn’t soft enough to practice on safely. After three volunteers tried it and ended up not being able to finish their session because of how much their hands and knees hurt, we took it out of the running. While we wouldn’t use it as a yoga mat, we decided it could make a beautiful meditation or prayer rug. 

Our Research

More insight into our methodology

When we started this research, we thought we would simply find great yoga mats at every price point, then offer readers options for their budget, yoga type, and physical condition. While many of us at Consumers Advocate have practiced yoga for years and can be considered pretty eco-conscious, we hadn't really looked deeply into the mats we were using, what they were made of, and how they could be affecting us or the environment. Most people seem to assume that if it's made with yogis in mind, it has to be environmentally responsible.

 

However, as we started looking into the materials used to make these mats - especially those that we had chosen for our "budget" category - we saw that this was clearly not the case. In fact, most of the mats had one thing in common: they were made with polyvinyl chloride, or PVC, a non-biodegradable, highly toxic material used in many plastic items.

The more we read about the material and how damaging it was, the more we realized that we could not, in good conscience, recommend any mats that used PVC. So our focus changed: we would only try and review mats that could be labeled eco-friendly.

To find the best of the best in the eco-friendly arena, we conducted thorough research on biodegradable materials and the mats that labeled themselves as such. We talked to expert scientists to understand the materials more fully; and we researched the companies that manufactured them, their other available options, as well as reviews from consumers across the internet. This led us to partner with the Ecology Center in Ann Arbor, Michigan, so they could test the mats we had in their lab and see if there was any toxicity in those materials.

We did not receive free products from any of these companies, and did not try or buy anything made from PVC. While we did order synthetic materials such as TPE and polyurethane, these materials were said to biodegrade in a few years under normal landfill conditions. This, however, does not mean that they're harmless, as we were to find out later.

We settled on 11 mats, making sure to have an array of different styles, thicknesses (holding to a minimum of 3 mm), and materials. We included some of the more common polyurethane and rubber, but also cotton, jute, and even one made from recycled wetsuits.

Once we received our mats, we took note of the packaging they came in. After all, a company’s eco-friendliness should extend to more than just the materials they manufacture products with. Disappointingly, it turned out that quite a few eco-friendly yoga mats are being shipped wrapped in plastic.

We had 10 volunteers from our ConsumersAdvocate team try each mat, taking them home every night and trying them out either in studios or at home, wherever they usually practice. To ensure that everyone was measuring the same things, testers were given some guidelines.

Among them:

While they were free to choose the routine that was right for them, even if it was very short, some poses were required. For example, because almost every yoga class will have a version of Surya Namaskar - that is, sun salutations - our testers were asked to perform at least one sequence. This was important because sun salutations include many of the most common poses practitioners will end up doing in a yoga class. We had them test kneeling poses too, to judge the mat’s cushioning.

We also asked testers - and no one complained - to end their session with a few minutes of savasana (corpse pose) to see how comfortable it was to lie down on the mat.

They were then asked to assess the mats’ thickness, odor, feel, grip in both wet and dry conditions, and how easy they were to clean.

We then tested them out on the field, so to speak, by taking them to a yoga class in El Yunque Rainforest (one of the perks of being based in Puerto Rico) and noting how they did.

Lastly, in addition to each user’s experience, we took a look at the manufacturers themselves - their return policies, warranties, and history of commitment to environmental causes.

After having tallied those results, we strongly feel we’ve found high-quality, eco-friendly mats-- while not for every price point, for just about every need.

 

 

What the lab results showed...

We sent 10* of our mats to the Ecology Center in Ann Arbor, Michigan, along with a standard PVC mat made by popular yoga mat manufacturer GAIAM, so we could compare the materials between our eco-friendly choices and traditional mats made from PVC. (*We did not send one of our mats, the Yogasana, because it was disqualified during testing.) 

Throughout our research, we did notice gaps in information about the newer eco-friendly materials, such as Polymer Environmental Resin and Thermoplastic Elastomers, which we were hoping the lab would be able to fill in. In general, though, we thought that manufacturers’ claims about their mats were probably true.

This, however, was not the case. 

While eight out of our 10 mats were made of the material they were advertised as being, two of them were not-- specifically, the Aurorae Synergy 2-in-1 and the Ajna Jute mat. 

Like many of the newer eco-friendly mats, Aurorae and Ajna advertise as being made from a material called Polymer Environmental Resin (PER). Many manufacturers of PER mats advertise their mats as a synthetic but biodegradable alternative to PVC that’s actually good for the environment. In fact, in their Frequently Asked Questions, Ajna describes the materials of their mat as “a type of eco synthetic rubber, and like jute, is bio-degradable.” It also says it contains “no PVC, heavy metals, formaldehyde, phthalates, phenols, PAH’s, latex, rubber, or silicone.”

However, when our partners at the lab tested the material, they identified both mats as being made from PVC. 

We contacted both companies to obtain comment regarding this discrepancy. Multiple attempts have been made to reach Ajna, but they have not responded. We will update this if and when they do. 

Aurorae’s CEO, Dennis Ingui, on the other hand, was very open and responsive to our emails. He stands by the safety of the material and put us in touch with his suppliers: Lansong Industries (alternatively spelled Lan Song Industries). 

Digging deeper into PER

Based in Taiwan, Lansong claims to hold the patent for PER and be the sole supplier for the material around the world. We could not confirm this since the patent application we did find in the United States was abandoned before it was registered. (This, of course, doesn’t mean they don’t hold a patent somewhere else). Shipping records from U.S. Customs do show that, aside from Aurorae, Lansong also provides mats to one of the biggest names in yoga, Hugger Mugger.

Screenshot Patents.Google.com, June 20, 2019 

Representatives from Lansong acknowledged, via email, that PER is made from PVC but that, unlike PVC, it is non-toxic and biodegradable. They claim that it retains the durability of PVC, while doing away with the harmful toxins traditionally associated with it. They also told us that the chlorine found in PVC is safe, as it is stable and unlikely to seep out. To prove its biodegradability, they provided us with a biodegradability/compostability report, which states that their mats partially degraded within a span of six months and did not seem to leach toxins into the soil. 

It’s worth noting though that, according to the scientists we talked to and our own research, having a piece of plastic break down into parts under certain conditions, does not prove it’s  biodegradable, or even that it’s good for the environment. In fact, having plastics break down into pieces can potentially cause more harm than good

Gillian Z. Miller, Ph.D., senior scientist for the Ecology Center, told us that the difference between these PER mats and traditional PVC is the presence of a different type of plasticizer, specifically DOTP. (In our own research, we found studies showing that DOTP is considered to be fairly harmless to human beings.) 

But the use of DOTP instead of toxic plasticizers does not make PER a different material, or set it apart from many other brands who make PVC mats. In fact, the GAIAM PVC mat we had tested had exactly the same components as the PER mats. The difference? GAIAM clearly labeled their mats as PVC, while most PER mat sellers do not. 

It’s important to note that there’s no evidence showing that PER or the other PVC mats present any type of health risk upon contact. Lansong Industries says - and we confirmed - that their material obtained the globally recognized STANDARD 100 by OEKO-TEX® certification, which tests for a lengthy list of possible toxins. 

But, according to environmental experts we talked to, removing toxic plasticizers from PVC products does not an eco-friendly product make. 

The greenwashing of your yoga mat

“There isn’t a yogi in the world that could twist themselves into a position that’s as crazy as a company does when it claims that any PVC product is eco-friendly,” said Charlie Cray, senior research specialist from the organization Greenpeace. To them, the problem with PVC goes much further than the additives. “It is toxic from production to disposal, there’s dioxin, for example, associated with every stage of the process.” Dioxin, a byproduct of industrial manufacturing, is classified as a known cancer-causing agent and environmental pollutant. 

According to our partners at the Ecology Center, and the guidelines set by the Federal Trade Commission, rebranding PVC as an eco-friendly material could be a prime example of an ever-growing phenomenon called “greenwashing.” 

As the concern for the environment grows, an increasing number of consumers are looking for eco-friendly alternatives to the products they already use. Enter: greenwashing, a form of marketing or PR spin used to promote run-of-the-mill products and companies in a way that makes them seem environmentally friendly. 

What’s in a name?

Some companies have been known to play with words in order to make it seem like a product that’s not really eco-friendly, is. 

Take PER’s full name: Polymer Environmental Resin or Polymer Environmentally Friendly Resin, as it sometimes appears. Since PVC has a pretty poor reputation in environmental circles, using Environmental and Resin in the PER name might lead most people to believe they’re buying an eco-friendly alternative, when testing at the Ecology Center established that it's essentially PVC with different additives. 

The other PER mat we tried, Ajna, describes the material as an “eco-synthetic rubber” that is “free of PVC,” when as we said above, even the PER manufacturer acknowledged that the material is made from PVC. However, adding eco- and rubber to the name can make it sound much more attractive.

While this doesn’t mean that these mats can pose an imminent danger to your health, it does point to a larger issue: when you’re trying to be a more conscious shopper, how can you tell the truth from the marketing?

The Federal Trade Commission (FTC) has issued guidelines regulating the kind of language companies can use to market eco-friendly products truthfully, some of which are applicable to yoga mats. For example:

Biodegradability

An item can only be called biodegradable if its components will completely decompose into elements found in nature within a short period of time after “customary disposal.” If the item will not decompose in places where they would usually be disposed of - for example, landfills - within one year, calling it biodegradable could be considered deceptive. 

Non-toxic

For a company to claim that a product is “non-toxic,” it must be considered harmless both for humans and the environment. Companies claiming their products are not toxic, must be able to provide scientific evidence that their product and packaging is not harmful to humans OR the environment. 

Recyclable

Many companies will call their products recyclable, even though the material can only be recycled at very specialized facilities that most consumers don’t have access to. According to the FTC, companies should be clear about these claims by specifying whether that item is only recyclable at certain locations.

 

The FTC provides guidance on many other eco-friendly claims and -- if you really want to hone your “spot the greenwashing” skills -- they are an essential read. 

Helpful information about Yoga Mats

If you're just starting to do yoga, it might seem smart to buy the cheapest mat at the discount store, or maybe just borrow one from the studio or gym. Most of us have done so at one time or another. However, once you’ve committed to your practice, investing in a good mat will become essential for many reasons.

To start, if you’re even a teensy bit of a germaphobe, borrowing studio and gym mats is not for you.

While most yoga studios do clean their mats, many will do so at the beginning and end of the day, but won’t have time to do so between classes. In research published by the National Institutes of Health, surfaces at fitness centers were found to contain a smorgasbord of bacteria, including salmonella, staphylococcus, Klebsiella, and micrococcus. When you add in the porous surfaces of most yoga mats, along with the heat and humidity of a class, yoga mats might be considered the perfect breeding ground for these organisms to multiply.

In addition, unlike restaurants and gyms, yoga studios’ sanitation standards are not strictly regulated. So if you do have to use studio mats, make sure to wear long pants to minimize your skin’s exposure. However, if you’re committed to yoga, it’s time to think of getting your own high-quality mat, which can support you and your practice.

The real cost of a cheap mat

Thirty-six million Americans practice yoga every year, spending more than $16 billion on yoga classes and gear, including mats. While it’s difficult to ascertain how many of those billions go toward mats in particular, it’s safe to say that the best-selling mats are usually the cheapest.

Unfortunately, these mats also have notoriously short lifespans, which is problematic for a few reasons. First, of course, it’s a waste of money. But most importantly, these discarded non-biodegradable mats have a significant and negative ecological impact.

On the other hand, investing in a good mat - one made from biodegradable, non-toxic materials - can not only save you money in the long run but can also keep you safe, in more ways than one.

A mat with the right grip can help you maintain your balance, even when you’re sweating. It can especially help those who take Bikram or Ashtanga yoga, who often find that sweating on a mat can make it slippery, making poses harder, and heightening the risk of injury.

A great mat will also provide enough cushioning. If you’ve been practicing on a cheap, thin mat, you might have found it difficult to do positions that require kneeling, like lunges or table pose, or found your wrists hurting after holding a high push up for more than a few seconds. A mat with the right thickness can protect your joints from injury during vigorous sessions and help you keep poses for longer.

As one of our testers said about one of our top-reviewed mats, the Jade Level 1: “I have a bony back which usually hurts on cheap mats, but I could practice for much longer on this one”.

But last but certainly not least, a great mat will be made from quality materials that are good for your own health and the health of the environment. As mentioned above, almost half of all yoga mats (and certainly most of the ones under $40) are made from PVC. And, while PVC is long-lasting, its durability comes at a steep cost.

PVC can be said to be a pollutant throughout its whole life cycle: creating contamination during its manufacturing, leaching toxic chemicals while in use, and not biodegrading for hundreds or possibly thousands of years after disposal. It is also nearly impossible to recycle.

Many phthalates - chemicals added to PVC to make it soft and pliable - are classified as carcinogens by most health agencies around the world. In fact, in 2017, the U.S. Consumer Product Safety Commission (CPSC) banned the use of certain phthalates from use in children’s products, and multiple studies have found links between phthalate exposure during pregnancy and birth defects. This means that, if you’re a parent or an expectant mother, mats made from PVC should be especially worrisome.

But even if you’re not, and you do yoga regularly, it should still be concerning. Jeff Gearhart, Director of Research for the Ecology Center in Ann Arbor, MI, told us that “the phthalates involved in PVC are especially likely to be released even at room temperature. The hotter it gets, the more likely they are to be released”.

(As a non-profit focused on protecting consumers from toxic chemicals in everyday life, the Ecology Center has partnered with us in order to test yoga mat samples and ensure that the ones we tried - all said to be eco-friendly options - are actually safe for consumers to use.)

Ahimsa: Why eco-friendly matters

There are approximately 80 million yoga practitioners around the world, and perhaps the same unique combination of reasons for taking up the practice. While many in the United States and elsewhere approach it strictly as exercise, there are countless others that undertake yoga for its mental and spiritual benefits as well as its physical ones.

For those, yoga extends much farther than the mat. “We often call it yoga off the mat-- the asanas, the postures that we practice on the mat, that’s only a small aspect of yoga," says Dr. Lori Rubenstein, a Los Angeles-based yoga therapist and member of the advisory council for the International Association of Yoga Therapists. "It’s all this other stuff that comprise yoga, and the process of making a conscious decision that 'I’m going to choose a mat that is earth-friendly' can go with the principles of yoga, for example, ahimsa - which is not only about not harming each other, but also about not harming the environment."

In what is considered yoga’s foundational text - the Yoga Sutras - Indian sage Patanjali lays out ethical guidelines for practitioners to follow both in yoga and in their daily lives. First among these is ahimsa, or non-violence.

David Procyshyn, teacher and creator of the popular website DoYogaWithMe.com, also refers to the principle of ahimsa in his use of eco-friendly mats and clothing. "One of the most important principles of yoga is to be kind to the planet, so the irony is painful, just really painful. I wouldn't be surprised if the yoga industry is producing more toxic materials than other industries just because so many people buy polyester clothing to do a yoga class."

His concern about the use of toxic and non-biodegradable materials in both mats and clothing led him to start Plastic Free Yoga Revolution, an initiative to reduce the use of plastic in the yoga industry. "My plan is to get as many companies and organizations involved as possible and at the same time approach yoga studios to request that they commit to certain criteria to reduce plastics."

However, even if you practice yoga purely for its physical benefits and not its spiritual ones, knowing what your mat is made of is essential. As you'll see below, many materials could be just as harmful for the human body as they are for the Earth.

What's really in your mat

Yoga mats can be made from almost any material, varying in terms of durability, thickness, porosity, weight, and – last but not least - biodegradability and toxicity.

What's so bad about PVC?

Short answer: A lot, actually.

As we mentioned above, PVC can be said to be a pollutant during every step of the process, from its manufacture, throughout its use, and in the course of its disposal. And, although not much scientific testing has been done specifically on yoga mats and the repercussions of practicing on these types of materials, there are some things about PVC that we do know for sure.

Manufacturing PVC generates a significant amount of contamination and hazardous by-products. In the U.S. alone, PVC plants emit approximately 500,000 pounds of vinyl chloride, a known human carcinogen, along with other toxins, into the atmosphere. One of these toxins, dioxin, is classified as a Persistent, Bioaccumulative, and Toxic (PBT) chemical, in other words, “substances that can build up to levels that can be harmful to human and ecological health”. In fact, dioxin has been found in the tissues of every living species, from whales and polar bears to, of course, humans.

To make PVC flexible enough for household products (including yoga mats), manufacturers must add chemical plasticizers and/or heavy metals, many of which are also known to be harmful and which leach out over time, especially in warmer temperatures. These substances are known to be endocrine disruptors, chemicals that can cause developmental, reproductive, and neurological harm to both humans and animals.

In addition to all this, there is no way to truly recycle PVC and, in countries where trash is incinerated, the resulting emission of toxic chemicals can be hazardous to entire communities.

So, while the science on yoga mats per se isn’t in yet, the harm this type of material causes to the environment and communities where it’s manufactured or disposed of cannot be overlooked.

And yet, according to Procyshyn's research, “close to 50% of mats are still made from PVC.”  

There are obvious reasons for this. PVC is long-lasting, and mats made from this material often provide a fair degree of cushioning and traction at a low cost. However, it’s not only the budget mats that are made from it.

In the yoga mat industry, Manduka is probably the biggest player. The Manduka PRO line, which is made from PVC, is one of the most widely used by yoga teachers and committed students around the world. Although well-known to be pricey, Manduka mats are also incredibly long-lasting. So much so, in fact, that the company offers lifetime guarantees.

Because of their durability, Manduka claims that they're helping reduce mat consumption, since their mats will not end up in a landfill. The company also says that they use eco-friendly PVC, free from harmful phthalates and heavy metals, and that they manufacture without releasing any toxic emissions into the atmosphere. However, they provide little to no information about how exactly they do this. We contacted Manduka for an interview in order to get more details, but the company has not responded to our request. We will update this if and when they do so.

The company did release an eco-friendly line made from natural rubber, called the eKO, which we tested. It scored fairly well with our testers, with some praising the high quality of the mat, its cushioning, and how easy it was to clean; however, the overwhelming consensus was that it lacked traction, making it hard to hold onto poses.

The materials we chose

Polyurethane

Some mats labeled as eco-friendly, including two of the ones we tested in-house, Lululemon and Liforme, are made from polyurethane (PU).

While there are different varieties of PU and ecologically speaking, it is better than PVC, PU is not exactly a friend to the environment either. As a petroleum-based material, it cannot be considered renewable. Additionally, many varieties of PU contain isocyanates, toxic compounds referred to as carcinogens by the Occupational Safety and Health Administration. While this doesn't mean that a yoga mat made from PU is necessarily toxic, the composition of these mats and the additives they use can vary wildly, making it difficult to ascertain what is toxic and what isn't.

The exception is Liforme, which manufactures their mats with what they label eco-polyurethane. To prove the quality of their components, the company commissioned an in-depth analysis of its mats, which determined that the blend of polymers they were using was non-toxic, as well as biodegradable in one to five years in normal landfill conditions.

See our review section for our take on the Liforme mat, which ended up being one of our testers' favorite mats.

TPE 

TPE, or thermoplastic elastomers, are also a common material used to make so-called eco-conscious mats. Like PU, TPE is often a mix of synthetic materials including plastics and rubbers. They can usually be recycled; however, because the term TPE can encompass a wide variety of synthetic materials, and most manufacturers are vague about what exactly goes into their particular TPE mix, it's difficult to tell what exactly they are made of.

TPE yoga mats are usually labeled as PVC-free and since TPE doesn't need phthalates to be pliable and soft, it will also be free of those. However, this doesn't mean it's free of toxicity. This makes it important to ask manufacturers to explain exactly what is in their particular mix.

In our testing, we had one TPE mat: the ISHA Mat. While testers appreciated the cushioning it provided and how light it was to carry, the mat was slightly torn by the fifth day of daily - but not overly vigorous - use.

Polymer Environmentally Friendly Resin (PER)

PER has become fairly popular with eco-friendly yoga mat manufacturers. During our research, we did notice some gaps in information regarding the material, with some conflicting information as to what exactly went into making it. However, many manufacturers described it as a type of synthetic rubber which, like many types of polyurethane, was biodegradable and non-toxic. However, once we submitted samples to the lab and talked to PER manufacturers, it became evident that PER was actually a PVC product. By the time we received the lab results, we had already tested two PER mats - the Aurorae Synergy and the Ajna Jute mat. However, we have now removed them from the list of eco-friendly mats due to the testing results.

Rubber

One of the other most common materials used in mats is rubber, either natural or synthetic. It's easy to see why - its strength, resistance, and flexibility make it an ideal material for everything from car tires to children's toys. On the con side, rubber is vulnerable to damage from heat and light, and can wear down under repeated stress.

Natural rubber is biodegradable and can be easily reused. Synthetic rubbers, on the other hand, are much harder to get rid of and difficult to repurpose, so when buying yoga mats, it's important to ascertain whether the rubber they're using is the natural kind.  

Rubber yoga mats offer several advantages, including excellent cushioning and grip. Our team of testers tried three mats made from natural rubber: Jade Harmony, Jade Level One, and Manduka eKO Lite. While they all tested fairly well performance-wise, our testers had concerns about the Jade mats' sturdiness and durability. The Level One showed signs of fraying after five days of continued use, and many former users cite the Jade Harmony's lack of durability.  We love that Jade will plant a tree for every mat sold; however, even using the most eco-friendly material is not enough to offset a short mat lifespan, which only creates more waste.

Cork

Cork might just be one of the most environmentally friendly materials on the planet. Although mostly associated with the familiar stoppers used to top wine, cork is hugely versatile and is easily used to anything from flooring to thermal insulation to, of course, yoga mats.  It is quickly biodegradable, easily recycled, and completely renewable. Much like shearing sheep to obtain wool, cork is harvested by carefully removing the bark, leaving the tree otherwise intact. As another plus, cork can also grow without much maintenance, without the need for pesticides, irrigation, or pruning.

Cork yoga mats offer a long list of benefits. While the surface is smooth to the touch, its traction increases with moisture, making it a great option for those who sweat during their practice. For those who practice in a studio, cork provides natural protection to some of the most common bacteria found in fitness facilities.

Among the mats we tested, we tried the Tranquility Essentials Cork 5mm mat, a natural rubber/cork hybrid. This mat, which placed among our top three, received rave reviews from almost all testers.

Jute

In terms of environmental friendliness, you can't get much better than jute. Often called the “golden crop”, both for its color and its value, jute is mostly grown in India and Bangladesh, making it also a source of economic development for the communities that cultivate it. Considered a highly renewable resource, jute is one of the fastest growing crops in the world, often reaching maturation in four to six months, easily outpacing quick-growing bamboo and cotton.

Additionally, when compared to other crops, jute needs little water, maintenance, or pesticides. Because of its strength, it is also versatile and often made into clothes, bags, and other household items. It can also be made into yoga mats.

The advantages of a jute mat are many: naturally antimicrobial material, easily cleaned, and – depending on how it’s made - great grip.

In our testing phase, we tried one organic jute mat, the Ajna. It received poor to mixed reviews from our testers, with many indicating that it offered little traction, would slide on tile, and the texture was too rough on their hands and knees. We believe this isn’t representative of all jute mats, however, and we will try others in the future to see how they fare.

Cotton

Considered the king of fabrics, cotton is ubiquitous in modern clothing and widely thought of as a superior alternative to synthetics such as polyester. And, while its environmental friendliness is up for debate given how it’s grown, the pesticides used, and the dyes most manufacturers add, it is still a renewable resource and completely biodegradable.

However, while cotton has many advantages as a fabric, it presents some drawbacks when it comes to yoga mats. Mats made from cotton do not offer the best grip (unless they add another material for the stickiness factor) and can slip on the floor. This makes them appropriate for slow, restorative practices, but not for vigorous yoga such as Ashtanga or Bikram.

Our testers tried Yogasana, a handmade cotton mat made by weavers in India. While our testers loved the look, smell, and feel of it, the consensus was that it was difficult to use due to how rough it was on the hands and knees. Because the website states that the mat grows softer with washing, one of our testers did just that. Unfortunately, it took 48 hours to dry and, although it grew slightly softer, it wasn't enough to be able to use it comfortably. On the other hand, reviews for the mat and others like it online lean towards the positive. The manufacturers of the mat say that they use part of its earnings to help pay for their workers' children's education, which is admirable. Additionally, because of the beauty and quality of weaving, we would consider it for meditation and pranayama (yogic breathing), but not for vigorous yoga practices.

Alternative materials-- in our case, recycled wetsuits

In the surfing world, wetsuits can present a bit of a dilemma. “For the most part, surfers are a very environmentally conscious group, so it's frustrating to truly need something like a wetsuit, which doesn't decompose,” said Shannon O’Keefe, who has been surfing for 10 years.

Most wetsuits are made out of petroleum-based neoprene, which is not biodegradable. And while neoprene can stick around for lifetimes, wetsuits themselves have a short useful life, with most lasting only between one and five years due to rips, accumulated salt, sun exposure, or just the loss of its ability to insulate.

“While there are now companies like Patagonia making biodegradable suits, many of us still have older wetsuits lingering in our closets that we don’t even know what to do with”, added O’Keefe.

Enter Suga, a California-based yoga mat manufacturer who has found a good use for the discarded gear. Founded by surfer, yogi, and former environmental attorney Brian Shields, Suga recycles discarded wetsuits by turning them into yoga mats. The company will also accept its own mats back to recycle them again.

Make sure to read our review of the Suga Mat, which ended up being our testers’ favorite mat.

Your Practice Determines Your Mat

Types of Yoga

HATHA YOGA हठ

Most types of yoga practiced in the West can be referred to as Hatha yoga. Hatha, meaning willful or forceful action. can also be described as the yoga of activity. Most Hatha yoga styles will have poses in common. However, each will emphasize different theories and aspects of practice.

Because of this, there is no “one mat fits all” when it comes to different yoga types. Practitioners of Restorative or Yin Yoga will have much different needs than those who do the more forceful Ashtanga sequences.  

While there’s plenty of variety, most studios in the United States will offer at least one of the classes below:

Vinyasa

Vinyasa or Flow usually refers to a style that involves flowing movement connected by the breath, usually Sun Salutations or similar poses. These classes can range from the slow to the very fast-paced and challenging.

If you regularly practice Vinyasa or classes with very flowing movements, you might do best with a smoother mat, that doesn’t offer as much traction but lets you slide from one pose to the next. Look for cork or closed-cell natural rubber mats, which can let you flow easily but still offer just enough grip to keep you steady.

Ashtanga and Power Yoga

Ashtanga yoga is one of the most vigorous and challenging types of yoga, with a prescribed sequence of movements that flow from one to the next without pause. It consists of six series, starting with the “primary”, which is appropriate for beginners.

Prepare to sweat when you go to an Ashtanga class and make sure your mat can withstand humidity, while still offering enough grip to do very strenuous poses. Mats like the Jade Harmony and other open-cell mats that offer a lot of traction are ideal, however, they are notoriously hard to clean. On the other hand, our top pick, the Suga mat offers that rare combination of easy maintenance with plenty of grip. Click here for our review.

Kundalini

Sanskrit in origin, the word Kundalini describes the arising of divine energy and consciousness that is said to uncoil like a serpent when the right conditions are in place. Kundalini yoga aims to provide those conditions through a series of movements, chanting, and breathing patterns.

Kundalini practitioners strongly believe that natural materials are essential for the energy to flow, so cork, jute, and cotton mats would be best for this practice.

Restorative and Yin Yoga

Like its name implies, restorative yoga aims to restore your body and nervous system through long stretches and slow movements. Although sometimes used interchangeably, restorative and yin yoga are not the same. Yin Yoga involves deep, active stretches held for a minute or more, while restorative does not involve active stretching. In both cases, whether restorative or yin, you might spend a long time on a single pose, making a comfortable mat, with plenty of cushioning, essential to your practice.

Look for dense, thick mats like some of our favorites - Tranquil Yogi Cork and Suga Recycled Wetsuit Mat, which testers found extremely comfortable.

Iyengar

Iyengar yoga’s focus is on precise alignment. Practitioners will usually hold poses for much longer – especially standing poses – in order to perfect their posture. Because of this emphasis, it encourages the use of props – belts, chairs, blocks, or blankets – to help even beginner, not-yet-so-pretzel-like students get the benefits of the pose.

The Liforme mat, Tranquility Essentials, and other mats with alignment guides would be perfect for Iyengar yoga.

Bikram and Hot Yoga

Bikram Yoga is the original hot yoga. Since sweat is believed to detoxify the body, Bikram yoga studios are carefully calibrated to stay at 100 degrees or more, with a high humidity factor. While traditional Bikram yoga follows a strict sequence of 26 poses, classes labeled as Hot Yoga can deviate from that sequence, while still keeping the heat and humidity of Bikram studios. Just as with Ashtanga above, it’s essential to have a mat with plenty of traction and grip to prevent sweat from making you slip.

Special Considerations

In addition to the types of yoga you practice, there are other situations that warrant special attention when it comes to choosing a mat.

Practicing when you’re injured

While most Americans might view yoga as a way to relax or exercise, many are also finding out the benefits it can have as a therapeutic intervention for injuries and chronic pain.

While similar to physical therapy in many ways, yoga therapy goes several steps further by aiming to treat a person’s lifestyle as well as their injuries.

Dr. Rubenstein does both. She considers yoga therapists as “lifestyle management experts”, whose prescriptions might include physical exercises, along with chanting, meditation, and Ayurvedic diets.

There’s plenty of evidence to back up the claims by most yoga teachers and therapists. Study after study show that a consistent yoga practice can significantly help lower blood pressure, strengthen cardiovascular health, help cancer patients tolerate radio- and chemotherapy much better, among other numerous mental, neurological, and emotional benefits.

Benefits are especially evident when it comes to musculoskeletal injuries. A 2013 study conducted by Johns Hopkins University found that a comprehensive yoga program tailored for those with osteoarthritis and rheumatoid arthritis improved pain symptoms by up to 40%.

But, while the benefits are many, there are special considerations to take into account when you have an injury, aren't used to being active, or have sensitive joints.

The kind of yoga matters, as does the mat you use.

For someone with joint pain, arthritis, or back pain, says Dr. Rubenstein, the cushioning of the mat will be extremely important. For back pain, she adds "you'll do a lot of poses on your back, so it's important that you're comfortable."

However, she adds, thicker is not always better. For someone with balance issues, for example, “We might actually want a thinner mat so that it won't challenge their balance, and then progress toward the thicker mat as part of their therapy."

Our mats were tested by 10 staff members with varying degrees of experience in yoga. Some of our testers had physical conditions that could require special considerations like the ones listed here. Their experiences were prioritized when choosing the best mats for joint pain or injuries.

Practicing while pregnant 

“For pregnant women, yoga can be a great way to build and maintain strength and flexibility in a safe and gentle manner”, said physical therapist Shayna Shefrin, who specializes in pelvic floor dysfunction at the Sarasota Memorial Hospital. Shefrin taught prenatal yoga for a decade before she obtained her doctorate in physical therapy.

Yoga can help with pregnancy and even labor in significant ways. “Cat/cow pose, for example, can help optimize the position of the baby in the womb and downward dog may be helpful if the baby is in a breech position, giving space for the baby to turn,” she said. Conversely, she cautions that there are poses and types of yoga that pregnant women should not do. For example, any poses that require laying flat on the back or, of course, on the stomach. Pregnant women should also avoid hot yoga, as it can dehydrate the body too quickly.

For pregnant women, finding a mat made from safe, eco-friendly materials is especially important. Experts and health agencies worldwide advise pregnant women to stay away from phthalates, the chemicals traditionally added to PVC to make it more pliable. And, because other mats made from other plastic materials are often vague into what goes into making them, natural materials - for example, cork - could be a safer choice.

Other considerations include strong traction even when wet, so as to avoid any risk of falls, as well as “good firm support and padding, which is extremely important as the joints become lax during pregnancy due to hormonal changes,” said Shefrin.

 


Q&A with Gillian Z. Miller, Ph.D., Senior Scientist for the Ecology Center

Q: What kind of testing were the mats subjected to? 

A: We tested the mats with two techniques—X-ray fluorescence, or XRF, and infrared spectroscopy, or FTIR. XRF measures chemical elements, such as lead and chlorine, while FTIR identifies what type of plastic and major chemicals. For example, we used FTIR to determine that some of the mats were made of PVC with certain additives.

 

Q: Had you ever heard of PER before this testing?

A: I had not heard of PER before. I was surprised when I learned it stands for “polymer environmental resin,” a name that tells us nothing. It sounded like greenwashing, especially since PVC is not an environmentally friendly material.

 

Q: How did the PER mats compare to the PVC mat we sent? 

A: The test results from XRF and FTIR were highly similar for the two PER mats and the PVC mat. All three were primarily composed of PVC and the plasticizer DOTP, plus calcium carbonate as a filler.  

 

Q: To your knowledge, does the process the manufacturer [Lansong Industries] outline in the abandoned patent, make it any different from PVC? For example, would it make it recyclable when PVC isn't?

A: The process outlined is short on details. One thing that’s clear is PVC—manufactured elsewhere--is one of the ingredients. Typically, making flexible PVC involves mixing PVC pellets with various additives including a plasticizer. The patent application seems to describe, in vague terms, a similar process. It doesn’t make clear what’s different. It doesn’t explain why this PER would be recyclable or biodegradable or why it wouldn’t emit toxic chemicals when incinerated.

Judging from the supplier’s comments about PER, which are likewise short on details, PER appears to be plasticized PVC that doesn’t contain hazardous heavy metals or phthalates. Our testing supports this claim. But it doesn’t make the material eco-friendly or unique. PVC made without heavy metals and phthalates is common in consumer products these days. It’s a big improvement for sure, but does not avoid the toxic emissions from PVC manufacture or incineration and thus should not be labeled environmentally friendly.

 

Q: Does PVC without the traditional phthalates still present a hazard? 

A: According to current knowledge, PVC with a non-phthalate plasticizer presents less hazard to the user. But we also need to consider manufacture and disposal. The manufacture of PVC involves toxic chemicals regardless of what plasticizers are added later. Vinyl chloride factories, which make the main ingredient for PVC, pollute the environment and the people who live nearby with highly toxic dioxins. Workers are exposed to vinyl chloride and dioxins. Disposal is a problem, too. Regardless of plasticizer type, PVC isn’t recyclable in most locations and releases toxic gases when incinerated.

I also think plasticized PVC of any type is not an ideal choice when people are in close contact with the material. Plasticizer chemicals make up a lot of the material—often upwards of 20% by weight. They are liquid and tend to migrate out. And there are gaps in our understanding of their toxicities. So even if DOTP is present instead of phthalates, as a precaution I’d rather avoid using a yoga mat that constantly exudes a plasticizer.
 

Q: About the wetsuit mat (Suga), can we tell what kind of phthalates are present?

A: No, the technique we used detects ortho-phthalate esters (phthalates) as a class. There are lots of slightly different phthalates and this test doesn’t distinguish between them. Only certain phthalates are restricted from use in children’s products in the United States, but there is reason to consider the whole class to be chemicals of concern.

 

Q: Could you tell us more about TPE and what you found it consists of. 

A: TPE is a general term encompassing lots of different polymer combinations. It stands for thermoplastic elastomer. So if a yoga mat label says TPE, you can’t tell what type of plastic the mat is made of.  The one yoga mat we tested labeled TPE was found to be ethylene/vinyl acetate copolymer, also known as EVA or PEVA. This polymer is commonly used in hot glue and in craft foam stickers, and is an alternative to PVC in things like shower curtains. Despite the word “vinyl” in the name, it’s not the same as PVC. It is a better choice from an environmental health perspective.

FAQs about Yoga Mats


Why do I have to clean my yoga mat?

You should clean your mat to avoid the growth of bacteria over time and prevent it from getting a funky smell. Some yoga mats are made of materials that can absorb sweat and fluids (spilled water, etc.). Other mats may not be as absorbent, but can trap hair and dirt, so a quick wipe-down can keep the mat clean of debris.

How often should I replace my yoga mat?

Yoga mats should be replaced every six months to one year on average. Keep in mind that the durability of your mat depends on the material it’s made from, how it is being used (frequency/type of yoga) and whether it is being maintained properly. Check the manufacturer’s specifications for use and care recommendations.

What’s the best way to clean my mat?

Each mat manufacturer will offer specific instructions about how best to take care of their mat. However, if you lost the instructions or your mat never came with any, there are some standard ways to do it. You could spritz your mat using a mixture of two cups of water and a few drops of dish soap. You can then wipe off the mat with clean water, rub with a towel, and let air dry. If your mat is very dirty, you can submerge it in water and mild detergent, but make sure to rinse it off really well as detergent could make it slippery. You can squeeze out the excess water and roll the mat on a dry towel. It’s important to always hang your mat in the shade, as direct sunlight can make many materials deteriorate faster.
