Overall Rating: 7.8 / 10 (Very good)

Sleep Number makes a wide range of beds to fit every customer's needs and budget. Its products are perfect for couples, as their design allows each partner to adjust their side of the bed to fit their desired firmness without disturbing the other person. Though the company's beds are on the more expensive end of the mattress spectrum, this feature may be enough to justify the cost. Additionally, Sleep Number offers a 25-year warranty that goes above and beyond those provided by competitors. On a different note, customer reviews for the company veer toward the negative, yet that may be due to its large size and broad client base.

Sleep Number Product Features

Product Features - 7 / 10

Sleep Number mattresses are made of a combination of contouring foam layers and a layer of air pockets that can be inflated and deflated to reach the perfect level of firmness, which is expressed in the famous "sleep number." In beds that accommodate two people, the level of firmness of each side of the mattress can be adjusted independently, allowing each sleeper to make their side of the bed as firm or soft as they find comfortable. The company fails to list the exact materials used in the manufacturing of their mattresses.

Sleep Number offers six mattress models. The core line is composed of the c2 and c4 beds, which are the most affordable ones. The c2 model lacks a comfort layer, while the c4 features SleepIQ technology, which tracks sleep habits.The 360 Smart Bed line, on the other hand, has the p5, p6, i7, i8, and i10 models. The difference between these models is the thickness of the comfort layer. Additionally, the "i" models have a "temperature balancing sleep surface," that helps owners sleep cooler at night. All 360 Smart Beds have SleepIQ technology and Responsive Air technology, which respond to the sleeper's movements to adjust firmness automatically.

According to Sleep Number, its beds are not compatible with traditional box spring foundations, so their own base must be purchased. Customers can choose between the integrated base and a range of adjustable bases that control the position of the head and feet and may also feature foot warming and under-bed lighting.

Sleep Number Pricing

Pricing - 9 / 10

Sleep Number beds are on the more expensive side of the spectrum, though this can be attributed to the uniqueness of its product. The price below reflects the cost of the P6 Queen-sized mattress, which is the mid-range Sleep Number model. Likewise, the price of the adjustable bed is that of the FlexFit 2, also the mid-range model. Customers interested in purchasing a Sleep Number bed should note that a traditional box spring does not provide the right amount of support for a Sleep Number mattress. The company recommends purchasing its simple integrated base, which retails for $299, or a FlexFit adjustable base, which is non-returnable.

Service Features - 8.5 / 10

Sleep Number's 100-night sleep trial for its mattresses is fairly standard for the industry. However, its 25-year limited warranty for defects not associated with normal use is above the industry standard, applying not only to the mattress but also to the Firmness Control system. The SleepIQ module also includes a 2-year warranty. During the first two years, any repair or replacement needed is covered by Sleep Number at no cost to the customer. Thereafter, the repair or replacement cost is determined by a percentage of the current prices for the item in question.

Home Trial Details
Customers can try a Sleep Number mattress for 100 nights. If they are not satisfied with the product, they can contact the company's customer service to process a return. They will be refunded the purchase price of the mattress, less original delivery and return shipping costs. This home trial does not apply to the FlexFit adjustable beds frequently sold with the Sleep Number bed, as these are non-exchangeable and non-returnable.

Sleep Number Company Reputation

Company Reputation - 7 / 10

Sleep Number holds an A+ with the Better Business Bureau. It has a large number of negative customer reviews and complaints, though that is to be expected with a company of its size and age. These complaints seem to revolve around defects in the Sleep Number bed. Several customers also point out that adjustable bases are non-returnable and the 100-night trial only applies to the mattress itself, which suggests these customers may not have read the entire product description before their purchase.
