Some of the key strengths of the Sleep Number mattresses include:
- Adjustable firmness: because the amount of air in the mattress can be easily increased or decreased, the Sleep Number mattresses offer substantially more flexibility in terms of firmness than other types of mattresses.
- Extensive line of mattress options: with more than 8 mattresses available, customers can select from many choices with different features
Potential drawbacks for the Sleep Number memory foam mattresses include:
- No free sleep trial: while the company offers 100 nights to test out their mattresses, shipping costs, including for the return, are not refundable.
- High cost: the Sleep Number mattresses have hefty price tags relative to many of the other mattresses available on the market, especially from online, direct-to-consumer mattress companies.
Recently, Sleep Number has launched a separate mattress product, the it Bed. Click here to read our review of that mattress.

Sleep Number offers some mattresses sizes and options that are not usually offered by other companies. For example, the Split King or Split California King mattresses are designed to be adjustable independently at both the head and foot of the mattress. The FlexTop King or FlexTop California King mattresses are divided only at the head. As a result, these sizes allow the head of the bed on either side to move independently, but the foot of the bed moves together.
It is also important to be aware that prices and availability for these products are subject to change.
About the Sleep Number Mattresses
Sleep Number Mattresses Specifications
Sleep Number is currently offering 8 different mattresses (and the it Bed) through their website. These fall into four general categories: Classic, Performance, Innovation, and Sleep 360. Some of the features offered in the Sleep Number mattresses include:
- Dual adjustable air chambers: the backbone of the Sleep Number mattresses. Each side of the mattress can be adjusted to a specific “Sleep Number” by increasing or decreasing the amount of air in the chamber.
- Foam comfort layer: some models have a foam comfort layer on top of the air chambers. One model uses memory foam, but the others use different types of more plush foam toppers.
- Temperature regulating materials: Sleep Number does not provide much detail about the nature of these materials, but some models are advertised as including more breathable or cooling materials to prevent sleeping hot.
- SleepIQ system: the SleepIQ system uses sensors in the mattress to track your movement, heart rate, and other indicators of your sleep quality. This data can be accessed through a mobile app and integrated with data from fitness trackers and other sensor-based technology. The SleepIQ system comes with some mattresses and is an optional add-on for others.
- Sleep 360 system: this system uses data from your movements to proactively adjust the mattress through the night.
The key features of each mattress model are described in the table below.

Sleep Number does not disclose some aspects of their mattress specifications such as the density of the foams that are used in their comfort layers. They also do not provide detailed information about their temperature regulating materials. Without this information, it is harder to definitively evaluate the quality and durability of these mattresses.

Buying Logistics
Where to Buy

Sleep Trial / Refunds
Sleep Number offers a 100 night sleep trial. During this period, you can return the mattress if you are unsatisfied. While the price of the mattress is refunded in the case of a return, the customer is responsible for the original delivery and return shipping fees.
Delivery
Sleep Number does not offer free home delivery. For delivery of the mattress without any setup or installation, the cost is $89.99. Home delivery including setup and installation is $179.99. Some bed types, such as mattresses purchased with a FlexFit adjustable base, require home delivery with setup.
Warranty
Sleep Number offers a 25-year warranty with each of these mattresses. During the first two years of the warranty, the company will repair or replace any mattress with defects in materials or manufacturing at no cost to the customer.

Customer Service
Like many other major mattress sellers, Sleep Number (and its parent company, Select Comfort Corp.) has a mixed reputation for customer service. While the company appears to work to support customers, there have also been many complaints lodged about the company. Select Comfort has an A+ rating from the Better Business Bureau.
Mattress Performance
The driving feature of the Sleep Number mattresses is the adjustable air chambers. Overall, these mattresses have a strong reputation for providing comfort and support.
Support
Because each mattress can be adjusted in real time, the Sleep Number beds offer a high level of support. This is true especially for couples who may have different firmness and support preferences as they can each select their own individual sleep number. The experience of indepdnent reviewers and verified customer reviews both point to a track record of support.
Durability
The Sleep Number mattresses have an average track record of durability. However, unlike other mattresses, there are more components — such as the electronics — that can potentially malfunction and affect the bed’s performance. Some customers have reported issues with leaks from the air chambers.
Firmness
With the two chambers that can be inflated or deflated with the push of a button, the Sleep Number mattresses have more firmness options than any other mattress type on the market. Customers who prefer a slightly more plush overall feel can choose one of the options with a foam comfort layer.
Motion Transfer
Most of the Sleep Number mattresses do not have a highly responsive comfort layer. Only one of the options has a memory foam comfort layer, and memory foam has the strongest reputation for motion isolation. As a result, more motion is transferred on an airbed than on most all-foam, latex, or hybrid mattresses. Despite this, the adjustability of the Sleep Number bed can help to reduce unwanted motion transfer.
While not transfer of motion itself, some customers do report disruption from noise of the chambers inflating or deflating. This noise transfer may be a consideration for people who know they are very sensitive to sounds while sleeping.
Offgassing
Because the Sleep Number mattresses are delivered fully inflated and are not compressed, they do not have any significant reported issues with offgassing.
Sleeping Hot
Most customers do not have problems with sleeping hot on the Sleep Number mattresses. An exception may be with the i7, which has memory foam as its comfort layer, which can cause excess heat buildup when the mattress closely conforms to the body.
Intimacy
The rapid adjustability of the Sleep Number mattress allows it to be inflated to a level that does not interfere with sexual activity.
