Sleep Number is a well-known mattress manufacturer that got its start in 1987. The company became popular with its adjustable airbeds that offer complete sleep customization. They are particularly successful with couples thanks to the dual air-chamber technology, which allows either side of the mattress to have a different firmness rating. Sleep Number currently has an extensive range of options with the Sleep Number 360 smart beds, which are divided into three series: Innovation, Performance, and Classic. Each series has a variety of choices when it comes to firmness options (rated 1-10), materials used, and price point.

  • The Classic series is made up of two mattresses, the c2 and c4. These beds have a two-inch and three-inch comfort layer (respectively) that are both made out of gel-infused polyfoam. The c2 offers a firmness range of medium-firm (6) to firm (7) while the c4 ranges from medium (5) to firm (7). These mattresses are the thinnest and lightest, which helps to make them the most affordable options.
  • Three beds make up the Performance series: the p5, pSE, and p6. Both the p5 and pSE models have four inches of polyfoam for the comfort layer, with firmness ranging from medium-soft (4) to firm (7). The comfort layer for the p6 is also polyfoam but is five inches thick. This mattress ranges from medium-soft (4) to medium-firm (6).
  • The Innovation series includes the m7, i8, iLE, and i10 models. The m7 (sometimes marketed as i7) is slightly different because of its comfort layer, which uses five inches of gel-infused Memory Foam; its firmness ranges from soft (3) to medium-firm (6). The comfort layers of the i8 and iLE are both six inches of polyfoam with a firmness range of medium-soft (4) to medium-firm (6). The i10’s comfort layer is seven inches thick, made from a mixture of polyfoam and Memory Foam. It has adjustable firmness ranging from soft (3) to medium-firm (6). The Innovation series is the most expensive of the group and the beds are not available in smaller sizes.

Since the Sleep Number models are airbeds, the firmness for each one is adjustable. However, depending on which model you purchase, there are different levels of firmness that they can adjust to. On a scale of 1-10, with one being the softest, each series has a varied range available. The Classic series can adjust from 5-7, the Performance beds range from 4-7, and the Innovation series has a scale of 3-6. All of the beds use dual air chambers, which means that either side of the bed can be adjusted independently from the the other—a great feature for partners with different sleeping styles.


All Sleep Number products are available through the company’s website. White Glove delivery costs $199 for most customers in all 50 states, but those who live in remote areas may pay additional charges. Sleep Number has physical store locations in every US state, but they do not have any authorized third-party dealers. Standard ground shipping is available for some sleep products, but not mattresses.

Performance Series
Innovation Series
Classic Series

Sleep Number classic seriesThe Classic series Sleep Number beds are made up of three different layers. The c2 and c3 have two and three-inch comfort layers which are both made from gel-infused polyfoam. They also both use the 360 smart bed dual air chamber support core that allows for adjustable firmness. The cover of the c2 is made of rayon and polypropylene while the c3’s cover is made of polyester and polypropylene.

Performance Series

Sleep Number Performance SeriesThe Performance series beds all use the same dual air chamber core as the Classic series. The p5 and pSE mattresses have a four-inch comfort layer made of polyfoam and are covered with a rayon and polypropylene blend. The p6 bed has a five-inch polyfoam comfort layer covered with a polyester and rayon blend.

Innovation Series

Sleep Number Innovation SeriesThe Innovation series also uses Sleep Number’s dual air chamber core. All four mattresses also share the same cover layer—a polyester and polypropylene blend. The m7 bed has a five-inch gel Memory Foam support layer. The i8 and iLE both have a six-inch polyfoam support layer. The i10 uses a mix of Memory Foam and polyfoam for its seven-inch support layer.


Sleep Number exclusively ships mattresses via White Glove delivery for orders in all 50 states. This includes setup of your new mattress and removal of your old mattress. This service starts at $199, and customers in remote locations may be required to pay additional fees.

Sleep Trial

The in-home trial for Sleep Number mattresses is 100 nights, and returns are no cost to you. Dual-Layer purchases, which is a mattress pad offered by Sleep Number, only have a 30-night trial. Delivery fees are non-refundable if you decide to return the mattress.


Sleep Number mattresses come with an all-inclusive two-year warranty that covers any issues at no cost. That period is followed by a 23 year prorated warranty that starts with the customer being responsible for 28% of the retail price. Each year following, the percentage goes up 4% until it maxes out at 96% (which lasts for the last five years of the 25-year warranty).

Sleep Number Mattress Performance

Motion Isolation

Sleep Number air mattresses all have above-average motion isolation thanks to the foam comfort layers. The Classic series has the least amount of motion isolation due to the thinner layer of foam and the type of materials used. The Innovation series performs best with minimizing motion across the bed thanks to its seven inches of polyfoam and Memory Foam.

Edge Support

All three series of Sleep Number beds use the same basic set up for edge construction. The mattresses are average for edge support—they are better than most foam and latex beds, but not as supportive as other options.

Heat Retention

The Sleep number mattresses retain heat differently depending on the series; however, the deal air chambers do keep you cooler than average foam or hybrid mattresses. Each bed also includes a foot warmer that can be controlled with the SmartIQ app or controller. The Classic series offers the least cool sleep due to the materials used in its upper layers. Hot sleepers will find the m7, and i10 mattresses sleep the coolest because they both use gel-infused Memory Foam in their comfort layer that minimizes heat retention.


The Sleep Number 360 smart beds are all air mattresses, which has limited to no off-gassing. The only exception is the two models (m7 and i10) which use Memory Foam, which may have a slightly noticeable scent upon arrival.


The dual air chamber technology that is used in these mattresses provides a sufficient amount of support, especially if they’re adjusted to the highest settings. The Classic series and Performance series has the firmest beds which will give you the most support. The Innovation series has the softest beds and use the most foam, so they underperform compared to the Classic and Performance.


The 360 smart beds use multiple foam layers to conform to your body. The Classic series has the thinnest comfort layer, but they still have decent conforming qualities thanks to the adjustable firmness. The Performance and Innovation series are better options for side and back sleepers. They offer thicker comfort layers that provide pressure point relief and can be adjusted from soft to medium-firm.


Sleep Number beds have slightly lower durability than other airbed options. The Classic series and Performance series suffer from foam degradation after about eight years, which is less than the industry average of 10 years (especially considering the price point). The m7 and i10 models are less likely to have this issue due to the high-quality Memory Foam used in their comfort layer. All the series commonly have issues with leaking air chambers after years of use.


Airbeds are not overly springy, so switching positions may be more difficult on these beds. The Innovation series somewhat overcomes this with its thicker support layers, although foam is still not as good as innerspring or hybrid models. The dual air chambers also create an uneven surface at the center of the mattress, which can have a negative impact on sex.


Moving around on a Sleep Number mattresses is relatively quiet. The thick foam layers provide minimal noise. However, adjusting the beds with the Firmness Control system can be loud due to the air in its core chambers, and having the SmartIQ set to adjust while you’re sleeping could be noisy enough to wake you up.

What Type of Sleeper Is Well Suited to a Sleep Number Mattress?

Side Sleepers: Your preferred sleep position will have a significant impact on what type of mattress is the best for you. Side sleepers need a bed that will conform to your body and provides pressure point relief. The Innovation series is excellent for side sleepers who prefer a softer mattress and are average to below-average weight. That is because these beds come in with the softest firmness-rating and have the most foam used for support. The Performance series options are best for heavier side sleepers who need the same level of pressure point relief but require more support from their mattress. The Classic series will most likely be too firm for a side sleeper as the c2 and c4 are the firmest options from Sleep Number.

Back Sleepers: Back sleepers tend to require firmer mattress options that have some pressure point relief but won’t allow you to sink too far in. The Classic series has a firmness range that includes the firmest options of any Sleep Number bed, which is best for back sleepers who are averaged weight or higher. The Performance series does a great job of balancing comfort and support for back sleepers of all weights, and the Innovation series would only be recommended for back sleepers who are lightweight and looking for a softer sleeping surface.

Stomach Sleepers: Stomach sleepers need a fair amount of support to prevent back strain, which is caused by sinking too far into a mattress. Averaged weight stomach sleepers will find the Classic series’ firm settings and thinnest available support layer the most comfortable. The Performance series is excellent for average to heavier stomach sleepers as they allow your body to sink in a little but still provide a firm support core. The Innovation series is the worst choice for stomach sleepers due to the lack of firmer options and thick foam comfort layers.

Our Verdict

If you’re looking for a customizable sleep experience, Sleep Number is a great choice.

The SmartIQ technology allows you to adjust your bed to the perfect setting, which can be used as a smartphone app or optional Sleep Number Remote. Having been in business for so long, Sleep Number also has a reliable customer service and offers the longest trials and warranties.

However, these mattresses can get very expensive, especially in the larger sizes of the Performance and Innovation series.
