Tempur-Pedic vs. Sleep Number Mattress Comparison

Tempur-Pedic and Sleep Number are two of the best known mattress brands in the country. Despite similar levels of name recognition, the beds from these companies are quite different. Tempur-Pedic offers a selection of all-foam and hybrid mattresses constructed with premium memory foam, while Sleep Number specializes in airbeds with adjustable firmness levels and sleep-tracking technology.

One of Tempur-Pedic’s best selling models is the TEMPUR-ProAdapt. This mattress is available in an all-foam design featuring memory foam comfort and transitional layers, a high-density polyfoam support core, and a removable cover. You can choose three firmness levels for the all-foam TEMPUR-ProAdapt: soft (2-3), medium (5), or firm (7-8). You may also opt for a hybrid version of the mattress, which has a medium (5) feel and is constructed with a support layer of pocketed coils.

Sleep Number currently sells nine airbed models. Part of Sleep Number’s Classic Series, the 360 c2 Smart Bed (also known as the c2) is the brand’s most affordable model. The c2 is constructed with a comfort layer of gel-infused polyfoam, as well as two adjustable air chambers in the support core. You can add or release air to the chambers in order to change the firmness on either side of the bed. The c2 offers a firmness range of medium firm (6) to firm (7-8).

Despite a few similarities, memory foam/memory foam hybrid and airbed mattresses feel very different from one another. You should carefully consider your personal sleep needs and preferences before deciding whether a Sleep Number or Tempur-Pedic mattress is right for you. Keep reading to see how the TEMPUR-ProAdapt and c2 Smart Bed stack up to one another in terms of cost, construction, and performance. We’ll also discuss other models from these brands, as well as their shipping, return, and warranty policies.

How Are These Mattresses Built?

Every mattress model has a unique design, but most beds today are composed of the same general components. The top layers – known as comfort layers – are intended to cushion and conform to your body in order to support your spine and reduce pressure points. Comfort layers are usually made of contouring materials such as polyfoam, memory foam, or latex. Many mattresses have a transitional layer of polyfoam or minicoils under their comfort layers. The transitional layer should prevent you from sinking too deeply into the mattress.

The base layer of the mattress, also known as the support core, stabilizes and reinforces the entire bed. This ensures even support for your body and minimal sinkage along the perimeter when you get on and off the mattress, or sleep close to the edges. The support core may consist of high-density polyfoam, latex, steel coils, or air chambers, depending on the mattress type. Lastly, mattresses sold today are encased in fabric covers, which may be removable or non-removable.

How comfortable and supportive a mattress feels to different sleepers will largely depend on its material. Comfort, transition, support, and cover components can also affect how cool or warm the mattress feels, whether it isolates motion or alleviates pressure, and how long it will perform before a replacement is needed.

Tempur-Pedic TEMPUR-ProAdapt

The TEMPUR-ProAdapt is available in both all-foam and hybrid designs. Both versions contain the same comfort and transitional layers. The comfort layer consists of 4 inches of TEMPUR-ES memory foam, a proprietary material that is very soft and adaptive. The transitional layer is made of TEMPUR-APR memory foam, which is denser and more supportive than the comfort layer. The all-foam mattress is available with soft (2-3), medium (5), and firm (7-8) feels, while the hybrid is only available with medium (5) firmness.

Support core construction is one area where the all-foam and hybrid TEMPUR-ProAdapt models differ. The all-foam mattress features high-density polyfoam in its base layer. This material is used in the support layers of most all-foam mattresses. It offers decent stability, but you’ll still notice some sinkage along the edges – especially on models with soft or medium firmness levels. The hybrid, which has a pocketed coil support core, provides stronger edge reinforcement.

Altogether, The TEMPUR-ProAdapt measures 12 inches thick, making it a high-profile mattress. The bed also includes a removable, dual-layer cover that can be unzipped and removed for cleaning. Tempur-Pedic recommends machine-washing on a cool setting and air-drying. You should not use chlorine or “harsh stain removers” to clean the cover.

Sleep Number 360 c2 Smart Bed

The c2 is an airbed constructed with a 2-inch comfort layer of gel-infused polyfoam. The bed’s 6-inch support core contains two adjustable air chambers, one for each side of the mattress. The c2’s non-removable cover is made from a blend of rayon and polypropylene. Altogether, the c2 measures 8 inches thick. This makes it a low-profile bed, as well as Sleep Number’s shortest mattress.

Air can be added or removed from each chamber to adjust the firmness level on each side of the bed. Depending on how the chambers are adjusted, the c2’s firmness generally falls between medium firm (6) and firm (7-8). This range is fairly limited for a Sleep Number mattress, and airbeds in general. For example, some of Sleep Number’s more advanced models offer firmness ranges of soft (2-3) to medium firm (6), or medium soft (4) to firm (7-8). However, the bed is well-suited for any single sleeper or couple whose preferences gravitate toward firmer feels.

The c2 is also equipped with sensors that allow the mattress to track certain sleep patterns, such as time awake and asleep, REM cycles, and sleep position shifts. You can access your personal sleep by accessing the SleepIQ app – which Sleep Number owns and operates – on their cell phone or other smart device. Please note: you’ll need a Wi-Fi connection in your bedroom for the SleepIQ system to work.

How Do the Tempur-Pedic and Sleep Number Mattresses Feel?


The all-foam TEMPUR-ProAdapt offers what is best described as a “traditional memory foam feel.” The memory foam layers conform very closely to create a deep, pressure-relieving cradle for your body. Many people liken this sensation to sleeping “in” – as opposed to “on” – the mattress, but the polyfoam transitional layer beneath the memory foam prevents excessive sagging.

How closely the mattress conforms depends on the selected firmness. You can choose from three firmness levels for the all-foam TEMPUR-ProAdapt: soft (2-3), medium (5), or firm (7-8). The soft feel conforms very closely, making it best-suited to side sleepers who weigh 230 pounds or fewer and other people who prefer a deep body cradle. The firm feel conforms to a very minimal extent, and is better suited to back and stomach sleepers who weigh at least 130 pounds.

The medium feel is the mid-level option between the other two, and will be suitable if you like noticeable body-conforming without a deep sink. The hybrid TEMPUR-ProAdapt has a medium (5) feel, as well. The pocketed coils give this model a responsive surface feel, but the memory foam still conforms somewhat closely. We recommend the medium all-foam and hybrid TEMPUR-ProAdapt to side and back sleepers who weigh 230 pounds or fewer.

Describing the c2’s firmness is a bit trickier because – as an airbed – this mattress does not have a fixed firmness level. Instead, you can add air to its support core chamber to make your side of the bed feel firmer, or release air to create a softer feel. The bed is designed for dual firmness, so you’ll be able to adjust the feel for each side of the mattress independently. Firmness options for this mattress range from medium firm (6) to firm (7-8), depending on how much air is in that side’s chamber.

The c2’s polyfoam comfort layer conforms a bit, but not to the same extent as memory foam. Polyfoam is also a more responsive material, so you’ll experience some contouring with a light bounce on the surface.

Due to its firmness range, we recommend the c2 to any side, back, stomach, or combination sleeper who likes a medium firm or firm feel – which usually includes people who weigh at least 130 pounds. The bed’s shorter profile can also be helpful for people under 130 pounds who struggle getting on and off thicker beds.


When discussing mattresses, “responsiveness” refers to how bouncy the mattress feels. Some mattresses will respond quickly to your body, creating a noticeable bounce on the surface. In contrast, other beds respond slowly and do not feel as bouncy at first. Mattresses with noticeable responsiveness are usually easier to move on, and many couples prefer the feel of a springy mattress during sex because their bodies don’t sink too deeply.

The all-foam TEMPUR-ProAdapt falls into the latter category. The memory foam responds very slowly as it softens and adapts to your body, so you’ll barely notice any responsiveness as you sink into the mattress. This is a typical level of responsiveness for an all-foam mattress with a memory foam comfort layer and a polyfoam base.

The hybrid TEMPUR-ProAdapt has pocketed coils in its support core instead. Like other hybrids and innersprings, this mattress offers noticeable responsiveness from its coil system. That said, the memory foam layer is thick enough to temper the coils a bit. This results in a balance of bounce on the surface and close body-conforming – more responsiveness than the all-foam TEMPUR-ProAdapt, but less bounciness than most competing hybrids with thinner comfort layers.

The c2 offers some springiness due to its polyfoam comfort layer, which feels slightly more responsive than the memory foam found in the TEMPUR-ProAdapt models. Your body sinks a bit and the foam conforms somewhat closely, but you’ll notice a light bounce on the surface. Adjusting the mattress to its firmest feel will result in the most responsiveness, but the bed’s softest feel is still medium firm and fairly bouncy in its own right.

Airbeds are not particularly bouncy, but the c2 has a more responsive feel than the all-foam TEMPUR-ProAdapt. The hybrid TEMPUR-ProAdapt is the most responsive option due to its pocketed coils.

Edge Support and Ease of Movement

Mattresses with strong edge support maintain an even perimeter that won’t sink too much. This can make getting in and out of bed much easier, and also allow you to sleep more securely near the edges of your mattress. Beds with less perimeter support will sink deeply when you get up or sit down, and they won’t feel as stable if you like to sleep near the edges. As with bounciness, edge support can also affect ease of movement. You’ll have a much easier time moving across a mattress with well-supported edges.

The all-foam TEMPUR-ProAdapt sinks quite a bit when you sit along the edges. The firm feel offers the best perimeter reinforcement, but even then the support is average at best. Many all-foam mattresses earn lower ratings in this performance category due to their high-density polyfoam bases. Although this material is fairly supportive, the foam will soften as it ages and long-term compression often leads to deep sinkage.

The hybrid TEMPUR-ProAdapt provides stronger edge support, but you’ll probably still notice some sinkage – especially if you weigh 130 pounds or more. This is a common issue for softer hybrids and innersprings with thick comfort layers. Models with coil systems and thinner, firmer comfort layers typically sink much less.

For the c2, edge support somewhat depends on air chamber volume. When the chambers are full and the mattress is at its firmest, you’ll feel less sinkage along the perimeter compared to when the chamber is low and the bed is medium firm. However, the mattress provides decent overall edge support regardless of the selected firmness. You may notice some sinkage, but not to a bothersome degree that makes getting on and off the bed too difficult.


How cool or warm a mattress sleeps mostly depends on its material components. Some comfort, transitional, and support materials promote airflow to help the mattress maintain a comfortable temperature. Others do not circulate air as well, causing them to absorb and trap body heat and sleep excessively warm. Cover fabric is also important because some fibers are lighter and more breathable than others.

Heat absorption is a common issue with memory foam mattresses, and the all-foam TEMPUR-ProAdapt is no exception. Memory foam often traps more heat than other comfort layer materials because of its relatively dense composition.

The TEMPUR-ProAdapt has a fairly thick comfort layer, to boot. This results in a high level of body heat retention. Models with a soft feel tend to sleep the warmest because the foams conform very closely, causing you to sink more and restricting surface airflow in the process – but even with a firm feel, you may find this mattress sleeps uncomfortably hot.

Temperature neutrality is a bit better with the hybrid TEMPUR-ProAdapt. The mattress still has a 4-inch memory foam comfort layer that can trap heat for some, but the coil system promotes strong airflow to help the mattress stay relatively cool. Keep in mind, however, that this mattress sleeps somewhat warm for a hybrid.

The c2 sleeps fairly cool. The polyfoam comfort layer can trap body heat but the material is infused with cooling gel, which may help minimize excessive warmth on the surface. The bed’s support core promotes airflow, as well. You probably won’t sleep too hot on the c2 unless you tend to feel excessively warm on beds with foam comfort layers.

Our Recommendations

The TEMPUR-ProAdapt from Tempur-Pedic and the Sleep Number 360 c2 Smart Bed each excel in several areas, including some categories where they both earn favorable ratings.

The all-foam and hybrid TEMPUR-ProAdapt excel at conforming to your body, evenly distributing your weight, and alleviating pressure in the shoulders, lower back and hips. This can be attributed to the memory foam comfort layers found in these beds. Side sleepers in particular tend to prefer memory foam because the material contours closely while cushioning the shoulders and hips, which can improve their spinal alignment and prevent new pressure points from developing.

The c2 provides less body-conforming due to its thinner polyfoam comfort layer. Regardless of how full the air chambers are, the mattress also offers a fairly firm feel. These attributes make the mattress best suited to back and stomach sleeping – positions that often require supportive mattresses that won’t sag too much around the lower back, waist, and hips.

The hybrid TEMPUR-ProAdapt and c2 both sleep reasonably cool. The hybrid promotes steady airflow through its coil system, while the airbed absorbs a minimal amount of body heat and also has a breathable support core. These models offer decent edge support, making it easier for you to move across their surfaces, and they are also fairly responsive.

The Tempur-Pedic and Sleep Number beds perform well in some of the same areas, too. For example, all three mattresses are very couple-friendly – but for different reasons. The TEMPUR-ProAdapt models have thick memory foam layers that absorb and isolate motion very well, leading to fewer nighttime disruptions for co-sleepers, while the c2 offers dual-firmness controls that allow each sleeper to select a distinct feel for their side of the bed.

Durability is another shared strength. The Tempur-Pedic beds are constructed with premium, long-lasting memory foam that withstands wear and tear very well compared to the foams used in other brands’ mattresses. The c2, on the other hand, is very durable by design – airbeds have average lifespans of at least eight years, as long as owners properly maintain them.

Lastly, the TEMPUR-ProAdapt and c2 mattresses differ in terms of pricing. The all-foam and hybrid TEMPUR-ProAdapt models both cost $2,999 for a queen size. This price-point is on par with other Tempur-Pedic models, but also very high compared to other memory foam and hybrid mattresses. Tempur-Pedic offers free White Glove delivery (see details below) to offset initial costs a bit, but for many shoppers, these mattresses will be too expensive.

The c2, which costs $999 in a queen size, is much more affordable by comparison and has a very low price-point for an airbed. However, please note that customers in Alaska and Hawaii pay $1,199 for their c2 models when ordering online. In exchange for paying more for the mattress, you’ll receive the same shipping rate as customers in the contiguous U.S.: $199 for White Glove delivery.

Key Differences

The TEMPUR-ProAdapt and c2 share a few similarities, but overall, the all-foam and hybrid Tempur-Pedic models are quite different from the Sleep Number airbed. There are some slight differences between the two TEMPUR-ProAdapt beds, as well.

  • The TEMPUR-ProAdapt is available as an all-foam or hybrid mattress. Both versions contain comfort and transitional layers of memory foam; the all-foam model has a high-density polyfoam base, while the hybrid has a pocketed coil system in its support core. The c2 is an airbed with a polyfoam comfort layer and an adjustable air chamber support core.
  • You can select a soft, medium, or firm feel for your all-foam TEMPUR-ProAdapt. The hybrid TEMPUR-ProAdapt is exclusively offered with a medium feel. The c2 is an adjustable airbed, allowing you to set the firmness between medium firm and firm.
  • Both versions of the TEMPUR-ProAdapt contain two layers of adaptive memory foam. This material conforms very closely, creating a pressure-relieving cradle for your body. The c2 has a thinner polyfoam comfort layer that does not contour as closely.
  • The all-foam TEMPUR-ProAdapt has weak edge support. You’ll probably notice significant sinkage when getting on and off the mattress. The hybrid TEMPUR-ProAdapt and c2 have slightly stronger edge support, resulting in less sinkage.
  • The all-foam TEMPUR-ProAdapt is completely silent when bearing weight. This characteristic is common for foam mattresses. The hybrid TEMPUR-ProAdapt may produce some noise due to its coil system, but overall, the mattress is fairly quiet and shouldn’t be too disruptive. The c2, on the other hand, is somewhat loud. The chambers produce a noticeable whirring whenever you adjust the air volume.
  • The c2 is equipped with SleepIQ sleep-tracking technology. Sensors built into the mattress monitor how long you are asleep and awake each night, the duration of your REM cycles, how often you shift positions, and other data points to help you improve your nightly routines. You can access the SleepIQ app using any smartphone or tablet device, and the app is free of charge. The all-foam and hybrid TEMPUR-ProAdapt are not equipped with sleep-tracking technology.
  • The c2 costs $999 or $1,199 for a queen size, depending on where you live in the U.S. (Alaska and Hawaii residents pay more). This price-point is significantly lower than average compared to other Sleep Number models and competing airbed mattresses. The all-foam and hybrid TEMPUR-ProAdapt cost $2,999 for a queen size. These price-points make the mattresses more expensive than their average all-foam and hybrid counterparts.

Tempur-Pedic offers free White Glove delivery in the contiguous U.S. This service includes scheduled delivery times, in-home assembly, and old mattress removal. Sleep Number also ships mattresses via White Glove delivery, but you’ll need to pay $199 for this service. The delivery rate is the same for all 50 states, but if you reside in Alaska or Hawaii, you’ll pay an additional $200 for the mattress itself.

Other Models

In addition to the TEMPUR-ProAdapt models, Tempur-Pedic offers these additional mattress options.

  • The TEMPUR-Adapt, like the TEMPUR-ProAdapt, is available as an all-foam or hybrid mattress – both of which have medium (5) feels. Both versions contain memory foam comfort and transitional layers; the all-foam model has a high-density polyfoam base, while the hybrid has a pocketed coil support core. The TEMPUR-Adapt costs $2,199 in a queen size.
  • The TEMPUR-LuxeAdapt is exclusively available as an all-foam mattress. The mattress contains memory foam comfort and transitional layers, a high-density polyfoam support core. It also includes the same removable, dual-layer cover found on the TEMPUR-ProAdapt. You can choose a soft (2-3) or firm (7-8) feel for the TEMPUR-LuxeAdapt, which costs $3,699 for a queen size.
  • The TEMPUR-breeze°, like other Tempur-Pedic models, features memory foam comfort and transitional layers. This model’s defining feature is a temperature-regulating cover infused with phase-change material to help the surface remain cool. The TEMPUR-PRObreeze°, available as an all-foam or hybrid model with a medium (5) feel, has a cover that reduces surface temperatures by roughly 3 degrees. The TEMPUR-LUXEbreeze° reduces surface temperatures by 8 degrees; this all-foam model is available with a soft (2-3) or firm (7-8) feel.

Sleep Number also offers other mattress models in addition to the c2.

  • The c4 Smart Bed is the other model in Sleep Number’s Classic Series. This mattress has a 3-inch polyfoam comfort layer, and offers a firmness range that falls between medium (5) and firm (7-8). This mattress costs $1,499 in a queen size.
  • The Performance Series includes the p5, pSE, and p6 airbeds. These models have comfort layers that measure 4 to 5 inches thick. The p5 and p6 have firmness ranges of medium soft (4) to medium firm (6), while the PSE offers a range of medium (5) to firm (7-8). The Performance Series models cost between $2,099 and $2,799 in a queen size.
  • The Innovation Series also includes three models: the i8, iLE, and i10. These airbeds are constructed with comfort layers measuring 6 to 7 inches thick. The i8 and iLE have polyfoam comfort layers and offer a firmness range of medium soft (4) to medium firm (6). The i10 contains a mix of polyfoam and memory foam; its firmness range is soft (2-3) to medium firm (6). These mattresses cost between $3,099 and $4,999 in a queen size.
  • The m7 is the only Sleep Number airbed with a gel-infused memory foam comfort layer, which measures 5 inches thick. Its firmness range is medium soft (4) to medium firm (6). You’ll pay $3,099 for a queen size m7 model.

Company Policies

Before committing to a certain mattress model, we strongly recommend researching the brand’s shipping, return, and warranty policies. You can save a lot of money by reading the fine print and taking additional costs into account.


Tempur-Pedic offers free White Glove delivery anywhere in the contiguous U.S. You can schedule your delivery date and time with the couriers, who will assemble your mattress in a room of your choice and remove your old bed at no extra charge. Outside the contiguous U.S., expect to pay $600 for shipping where delivery is available.

Sleep Number also ships mattresses via White Glove delivery, but you’ll need to pay $199 for this service. This flat rate applies to all 50 states, but keep in mind you’ll pay more for the mattress itself if you live in Alaska and Hawaii.

Mattresses are not compressed for White Glove delivery. An adult of at least 18 years needs to be at your residence to sign for the mattress when couriers arrive.


Tempur-Pedic offers a 90-night sleep trial for each mattress purchase. The trial includes a mandatory break-in period of 30 nights, meaning you won’t be able to return the mattress for a refund until 30 nights have elapsed. Tempur-Pedic issues full refunds for all returns minus shipping charges, which you’ll need to cover.

Sleep Number offers a slightly longer 100-night sleep trial, but the same 30-night break-in requirement applies. You’ll receive a full refund if you return the mattress within 100 nights, minus shipping fees of $199 to $249 (depending on where you live). You may also exchange your mattress for another Sleep Number model, though you’ll need to pay the difference if the replacement costs more than the original.


Tempur-Pedic offers a 10-year warranty for all mattresses. The warranty is completely non-prorated. This means the company will cover all repair or replacement costs (minus transportation fees) if a defect develops in your mattress. Recognized defects include body impressions in the surface that measure at least three-quarters of an inch, physical flaws in the mattress that cause materials to deteriorate prematurely, and manufacturing flaws associated with the mattress cover.

Sleep Number’s mattress warranty spans 25 years, but it is partially prorated. You won’t pay anything to repair or replace a defective mattress during your first two years as an owner. Beginning in year three, you’ll pay 20 percent of the original price to have the mattress replaced. This rate increases by 4 percent for each subsequent year (i.e., 24 percent in year four, 28 percent in year five, etc.) until you reach year 21, at which point you’ll pay 96 percent of the original price for the remaining coverage period. If you believe your Sleep Number mattress has developed a defect, contact the company to initiate your claim.
