Helix Sleep, established in New York City in 2015, is a sleep brand that designs and sells custom-made mattresses, foundations, and mattress protectors. It takes an innovative approach to designing their mattresses, requiring customers to fill out a sleep quiz which it uses to determine the best mattress formulation for their needs.

Size and Firmness

Helix designs hybrid mattresses that cover all feel preferences, from soft and cushioned to firm and supportive. By using various types of foams in different combinations Helix is able to customize the firmness levels of their mattresses, even making two-sided, dual comfort ones to accommodate sleep partner's needs if chosen. Helix determines the best fit for their customers via an online sleep quiz, which takes no more than 2-3 minutes to complete. Based on the answers provided, they recommend the customized mattress they think will best suit them. 


They make mattresses in the following standard sizes:

Twin or Single

Twin XL



Full or Double



California King


Helix uses three different types of materials in their mattresses. Their Helix Dynamic Foam contours to the sleeper's body, yet remains cool. They also incorporate pocketed microcoils to provide pressure relief, optimize airflow, and reduce motion transfer issues. Finally, they incorporate various densities of high-grade polyfoam, in order to be able to fully personalize the mattress. For couples who have different sleep preferences, they have two options available. The first is a blended mattress, which incorporates both needs to obtain a happy medium. The other choice is a dual comfort mattress, which splits the mattress down the middle and customizes each side. 

Purchase Details

Helix gently compresses their mattresses and ships them free of charge directly to each customer's doorstep, in a box approximately the same size as a golf bag. Though every mattress is made-to-order, Helix estimates that it will arrive within 6-10 business days from the day the order is placed, and for approximately 1/3 of the cost of a retail mattress.

Helix's 100-night sleep trial is fairly standard, and in the event that mattresses are returned, Helix does their best to donate lightly used products to charities and housing facilities, or recycle them responsibly. They can offer exchanges for size replacements, but not for design or configuration modifications. 

Helix mattresses have a 10 year limited warranty, which covers defects not associated with normal usage, such as indentations of 1" or more. Normal wear requires that the mattress be supported correctly by a foundation or adjustable bed base. If the defect does fall under the warranty agreement, customers must process the return at their own cost, with proof of the original date of purchase. Their foundations have a 5-year limited warranty.

Customer Service and Reputation

Helix prominently features over 5,000 glowing reviews on their own page and has almost 2,000 Google Customer Reviews with an average rating of 4.8 out of 5 stars, but it can be difficult to obtain information on independent review sites such as the Better Business Bureau or TrustPilot, neither of which has entries for the company. A quick search through other 3rd party review websites reveals moderate complaints with the company, ocurring outside of the 100-night sleep trial return window. However, many customers reported 36% better sleep and increased rest during initial trials of the mattress.
