Both Sleep Number vs. Tempur-Pedic are very popular mattress brands in the bedding industry, and they have sold millions of products to clients all around the world – this is why comparing two high-quality and appreciated mattress manufacturers can be quite challenging.

Both companies have their pros and cons, and they are very similar in many aspects. Sleep Number vs. Tempur-Pedic? Which of their adjustable bases and mattress models is right for you? And which offers the best night’s sleep? It can be a complex question.

Sleep Number vs. Tempur-Pedic Mattress Comparison

The mattresses are rather different as well. Tempur-Pedic mattresses rely on an advanced technology initially created by NASA more than half a century ago to increase the survivability rate of the astronauts and reduce the negative effects posed by the G-force when the space shuttle left the Earth.

That being said, the Tempur material is known for its outstanding pressure-relieving benefits, and the formula that was used by NASA back then has been made commercially viable by Tempur-Pedic and its predecessors.

The Tempur-Pedic mattresses were introduced on the United States of America market back in 1992, and they are widely known for offering unparalleled support due to the unique technology that makes the memory foam very weight-sensitive and able to mold around the body, thus keeping the neck and the spine in perfect alignment.


One of the common aspects that both mattress manufacturers share is the fact that they both target people with back, shoulder and neck problems, and they both use advanced support systems designed to offer an unparalleled support and pressure point relief.

Both Tempur-Pedic and Sleep Number mattresses are designed to ensure a proper spinal alignment thanks to the advanced memory foam embedded in them, which automatically adjusts itself based on the weight and the body shape of the user.

When it comes to the Sleep Number beds vs. Tempur-Pedic beds, it must be said that Tempur-Pedic does not offer as wide of an array as Sleep Number, which is known to provide a plethora of beds that vary in size, shape and height.


One of the main difference between the Tempur-Pedic mattresses and the Sleep Number mattresses is the fact that the first ones tend to be more durable over the years, maintaining their shape and design almost intact as the years pass. This is why most customers believe that buying a Tempur-Pedic mattress is a great long-term investment.

The Sleep Number mattresses, on the other hand, differ regarding material and support mechanism, but they can be easily adjusted to meet the needs of a wide variety of users. Most of the Sleep Number mattresses feature natural rubber (latex), which is slightly more expensive than cotton or synthetic materials but is known for its health-related benefits and unmatched properties.

Natural rubber is hypoallergenic and naturally antimicrobial, has great anti-dust-mite properties, and is perfect for those who suffer from allergies or have hypersensitive skin.

Motion Transfer

In addition to the material that was used for making the mattresses, the motion transfer rating is at least as important – ideally, a good mattress should minimize the motion transfer while ensuring a good amount of support at the same time. In this case, the Tempur-Pedic mattresses tend to be superior to the Sleep Number mattresses, the latter not offering the same amount of support and not limiting the motion transfer to the same extent as the Tempur-Pedic products do.

Regarding customization, it must be mentioned that Sleep Number is somewhat superior to Tempur-Pedic, which is precisely what makes Sleep Number particularly popular amongst those who want highly-adjustable levels of firmness in their mattress. It is known that mattress firmness ratings vary anywhere from plush or extra plush to soft, medium-soft, medium-firm and extra firm, depending on the needs and personal preferences of each individual, so choosing between Sleep Number or Tempurpedic must be up to you.

A Closer Look At The Support Mechanism When Choosing Between Sleep Number or Tempur-Pedic

The Tempur-Pedic mattresses rely exclusively on the Tempur memory foam described above, which is known to minimize the motion-related disturbance as well as to offer an unprecedented relief of the pressure points, thus being a great choice for those who experience lower back arch pain, shoulder pain or neck pain. However, some models of Tempur-Pedic mattresses use additional materials designed to add to the comfort of the mattress, such as comfort layers, covers or cooling materials that aim to prevent heat retention, one of the main causes of mid-sleep awakenings during the night.

Foam Support vs. Air Support

This is where these two mattress manufacturers are radically different, given the fact that Sleep Number relies mostly on compressed air for its primary support, as opposed to innerspring or memory foam (the mainstay of Temper-Pedic mattresses). Although the air-support mechanism may not appeal to everybody, it is certainly great for those who want to get full control over the firmness and support level of the mattress, as they can easily and effortlessly adjust the comfort level by either adding or removing the extra air from the mattress.

The air-based Sleep Number mattresses come with a useful and handy electric air pump that can be easily connected to an energy source and it will do all the work on your behalf. This is precisely why the Sleep Number air beds are amongst the most sought-after ones in this particular mattress niche. The secret lies in the air-chamber technology which allows the user to effortlessly inflate and deflate the internal air chambers inside the mattress itself, easily adjusting the comfort level on either side of the Sleep Number mattress.

Cost of Maintenance

It is a known fact that memory foam mattresses tend to outlive the air beds and air chamber-based mattresses, mainly due to their sturdy and heavy-duty construction, and this is precisely why these mattresses are often accompanied by warranties against manufacturer’s defects that last anywhere between 10 and as much as 25 years, from the moment of purchase. Regarding the long-term cost of ownership, the Tempur-Pedic mattresses are far superior to the Sleep Number beds.

No products found.

When it comes to the overall care and maintenance (and all the costs associated with this), it must be said that the Tempur-Pedic mattresses are far cheaper to maintain as well, given the fact that the Sleep Number air chamber based mattresses may need some spare/replacement parts throughout the years, which does not happen with the Tempur-based Tempur-Pedic mattresses.

Motion Isolation

Another very important aspect that must be taken into account when comparing the Tempur-Pedic mattresses and beds to the Sleep Number mattresses is the motion isolation rating, as a good mattress will also offer unmatched motion disturbance relief.

It often happens that the material used for making the mattress itself is also responsible for the motion isolation (or the lack of motion isolation, for that matter). In this case, the Tempur-Pedic mattresses are far superior to the Sleep Number mattresses, as the Tempur foam was designed specifically for great support and efficient motion isolation.

In other words, due to the motion dampening qualities of their integral foam layer, the Tempur-Pedic mattresses tend to be more couple-friendly, providing a good night’s sleep even in the most active of circumstances.

Lifespan And Durability

Different mattresses have different lifespan and durability ratings, and this is determined exclusively by the materials that were used during the manufacturing process, as well as by the inner mechanism of support used by each mattress. The sturdier the construction of the mattress, the more likely it is to withstand the test of time without displaying any signs of breaking, wear, or tear.

Once again, when it comes to longevity and durability, customers seem to claim that the Tempur-Pedic mattresses are superior to the Sleep Number Beds, and everything comes down to their support mechanism.

Tempur-Pedic mattresses mold themselves around the shape and weight of the user’s body, thanks to the durable and high-quality memory foam, while the air-chamber-based Sleep Number mattresses tend to “hollow” or to malfunction a lot more frequently. Besides this, the latter also relies on an advanced electrical pump to inflate their air chambers that may also display signs of malfunctioning in the long run.

Tempur-Pedic mattresses do tend to lose their shape and some of their supportive properties as well, but this only happens after many years of use when they start to develop body impressions, to sag or to soften. However, the Tempur-Pedic mattress manufacturer does offer a warranty that allows users to have their mattresses repaired or replaced if the body impressions exceed a certain depth.

The Quality Of Sleep And The Overall Owner Satisfaction Rating

Both mattresses are comfortable and great to sleep on, as they are very quiet and notorious for the sound and silent sleep that they provide. However, the Tempur-Pedic mattresses tend to be motionless and a lot more silent than the Sleep Number beds.

Firmness Levels And Support Rating

Another very important factor that buyers must take into account, is the firmness and the adjustability of the firmness and the support rating. Both the Tempur-Pedic mattresses and the Sleep Number mattresses can be easily adjusted to meet the firmness requirements of different customers, the difference is that the Tempur-Pedic mattress firmness must be adjusted before the purchase, while the Sleep Number air mattresses can be adjusted at any time, due to their convenient air chamber-based support system.

In terms of firmness and comfort, the Sleep Number air beds are certainly superior, given the fact that these mattresses can be customized on either side of the mattress. This aspect is particularly important for couples, as each partner can adjust the desired level of firmness and support on his or her part, in an independent manner, without affecting the comfort of the other one. This is not possible with the Tempur-Pedic mattresses.

Customizable Zones

On the other hand, the Tempur-Pedic mattresses come with easily customizable areas, depending on the support requirements of each user. Some people need extra support around the lower back arch area (if they suffer from lumbar pain, for instance), while others need more support along their spine or down to their feet.

Regarding the firmness levels, both the Tempur-Pedic and the Sleep Number mattresses offer a wide array of choices, depending on the desired model. The level of firmness is often influenced by how thick the comfort layer is – the thicker the comfort layer, the softer the surface of the mattress tends to be.

Fortunately, this top layer can be easily adjusted and customized as well, before people eventually move on to purchasing the mattress. Additional mattress toppers are also available to further tweak the bed surface.


This is a relative aspect, as it is mostly related to the hypoallergenic character of each mattress. Both the Sleep Number air beds and the Tempur-Pedic beds are hypoallergenic and very user-friendly. However, the Sleep Number beds come with a cover that can be easily washed on a constant basis, thus allowing the user to maintain a clean and hygienic environment.

Washing an entire Tempur-Pedic mattress is virtually impossible (at least, not without preventing it from developing mold and mildew, as it is a known fact that these mattresses absorb moisture almost instantly and trap it inside). But users can still invest in a good vinyl cover that will protect the mattress, increase its lifespan, protect the sleeper against dust mites or bed bugs, and that is also very easy to wash and dry with the washing machine.

That being said, both mattresses can be easily adjusted so that they are hypoallergenic and hygienic all the time.

Chemical Odor Comparison

This is one of the most bothersome aspects related to purchasing a brand new mattress. Fortunately, the unpleasant chemical-like odor that most mattresses emit when new usually go away within several days if unpacked and aired properly.

Still, given the heavy-duty, memory foam-based construction of the Tempur-Pedic mattresses, their odor tends to be more persistent than that of the Sleep Number air mattresses. Besides this, the latter is also considerably more lightweight, thus being easier to air without any hassles.

The Pros And Cons Of Tempur-Pedic Vs. Sleep Number

Both mattress manufacturers have their pros and cons, and that is a known fact. Every customer must do his own in-depth research and carefully weigh the advantages and disadvantages of each mattress prior to making their choice, just to make sure that their money is truly well-spent. That being said, here is a deeper insight into the benefits and downsides of each mattress manufacturer.

The Benefits And Disadvantages Of Tempur-Pedic


One of the main benefits of the Tempur-Pedic mattresses is the fact that they are very durable, they have sturdy construction and tend to maintain the same high level of performance for more than a decade after purchase. Backed by a generous warranty against manufacturer’s defects, the Tempur-Pedic mattresses also tend to last longer than air beds.

Another significant advantage of these mattresses is the fact that the memory foam used for manufacturing the Tempur-Pedic mattresses features a precise and advanced mechanism of action specifically designed to reduce the motion transfer between co-sleepers, to absorb moisture and to adjust itself based on the weight and body shape of the user. This is a very high-density memory foam mattress that guarantees comfort and pressure point relief, and it also reduces the overall amount of tossing and turning during the night, giving a more restful night’s sleep.

Quiet Restfulness

These mattresses significantly improve the quality of sleep as well, given the unmatched level of support and pressure point relief that they provide. They are made of highly sensitive foam and designed to offer a restful and refreshing night’s sleep so that you will wake up fully recharged in the morning. Very silent and easily adaptable at the same time, the Tempur-Pedic mattresses do not make any noise, unlike the air pumps of the Sleep Number or the noisy coils of the classic innerspring mattresses.

Firmness under Warranty

Last, but not least, the Tempur-Pedic mattresses are also widely known for retaining the same shape and design, thus offering the same level of support over the years. Very few customers have complained about premature sagging problems regarding the Tempur-Pedic mattresses, as they are very durable and reliable and they have an outstanding lifespan. Besides this, even if the mattress shows any sign of premature sagging, you can have it replaced through the warranty, quickly and without the hassles.

Therapeutic Effect

Another notable advantage of the Tempur-Pedic mattresses is that they have a therapeutic effect, and this is one of the most important features of a good mattress.

Specifically designed for those who suffer from chronic back pain due to bad posture, the Tempur-Pedic mattresses are known to offer efficient pressure point relief and to come in handy for those who are trying to alleviate their pain naturally and effortlessly, without resorting to over-the-counter drugs or any kind. These mattresses are particularly beneficial for those with hip, shoulder, or back pain.

Heat Retention

Another aspect that customers tend to complain about is the heat retention. High-density memory foam does offer a great body support and ensures a restful night’s sleep but, as the same time, these mattresses can also attract and retain the body heat, thus creating an uncomfortable sleeping environment that can result in tossing and turning in the middle of the night.

Even so, this problem can be prevented by opting for one of the Tempur-Pedic mattresses that come with a cooling comfort layer, which is specifically designed to address this issue.


Besides this, just like any other high-density memory foam mattress, the Tempur-based products also product off-gassing, which is the bothersome chemical-like smell that customers feel a few days after they unpack the mattress.

The odor goes away, but most of the users are bothered by it. Last, but not least, the Tempur-Pedic mattresses can be very difficult to turn, as they are very heavy – this aspect can be a downside specifically for the elderly, who often have a difficult time lifting heavy objects.

The Benefits And Disadvantages Of Sleep Number Mattresses


Sleep number mattresses have a series of important benefits, and perhaps the one that most customers agree upon is the fact that they are easily adjustable regarding firmness level and support. You can easily turn the mattress into either super-soft, plush-like mattress, or into a very firm mattress that offers great body support.


Another benefit is that if you buy the mattress directly from the manufacturer, not only will you get a generous warranty, but along with their superior customer service you will also get a three-month trial that you can enjoy, in order to see whether the Sleep Number mattresses truly rise to your expectations.

Besides this, these mattresses tend to be a lot cheaper than the Tempur-Pedic mattress, thus being the perfect choice for those who are budget-conscious yet who do not want to make any compromise in terms of health, body support, pressure point relief, or comfort.

Portability and Versatility

The firmness level of the mattress can also be effortlessly adjusted on both sides of the mattress, therefore couples can customize their sleeping areas without interfering with one another.

Given the fact that the Sleep Number mattresses are based on air, they are very easy to transport from one room to another, they are easy to clean and store and users do not have a difficult time turning them or changing the sheets. Besides this, just like any other type of air bed available on the market, these are also very versatile and can be used both indoors and outdoors.

A very significant advantage is that while most air mattresses are designed for temporary use (and are generally suitable for occasional use in the guest room), these are built to last and can be used permanently, for years to come.


A common benefit that both mattress manufacturers share is the fact that they promote less tossing and turning during the night. Restlessness and mid-sleep awakenings are very common and particularly bothersome for most users, especially for those who aim for a deep and truly recharging REM sleep, and the last thing they want or need is to wake up multiple times in the middle of the night.

Fortunately, this is not the case with the permanent use air mattresses by Sleep Number, which are specifically designed to provide an efficient and unrestrained pressure point relief, thus ensuring a soothing, refreshing and restful night’s sleep. You will wake up refreshed in the morning, ready for a brand new day.

The mattresses are highly adjustable – it is known that the support and firmness needs of users tend to change as the years pass by, and it is important to opt for a mattress that can keep up with these ever-changing requirements.

Fortunately, the Sleep Number air mattresses can do just that, as you can make the mattress be either extremely soft and comfy (if you enjoy that “sink in” effect) or very firm if you suffer from a chronic condition that requires your body to be perfectly aligned all the time. These advanced customization options are great for people with different comfort needs.


One downside of the Sleep Number air beds is the fact that given their air-based mechanism of support, it is not uncommon for users to invest in repair and maintenance. That being said, these mattresses may require some replacement parts in the long run, and not everybody is comfortable with paying extra money for that (in most cases, these spare parts are not covered by the warranty. Therefore you will have to pay for them yourself).

Noisiness and Air Loss

There are some downsides regarding the Sleep Number mattresses that should not be ignored, and the ones that customers tend to complain about most of the time in mattress reviews include the noises that take place whenever you try to adjust the comfort levels by either adding or removing air from the mattress.

In addition to this, these air chamber-based mattresses can also experience constant losses of air, which can be a burden for those who do not have the time (or who simply do not want to) constantly make sure that the mattress offers enough support and comfort.

If the Tempur-Pedic mattresses tend to retain their shape and therapeutic properties over the years, the Sleep Number mattresses do tend to sag in the middle, thus causing major discomfort and having the opposite effect for those with back problems. If the mattress starts to sag and loses its support, then people with back problems will resent even a more intense pain, as their spine is no longer correctly aligned.

Return Policy And Warranty Comparison

Both mattresses are accompanied by long-lasting warranties offered by the manufacturer, although they are often limited to manufacturing defects. The Tempur-Pedic mattresses come with different warranty levels, but generally speaking, they come with a total of 25 years of coverage – the first ten years are non-prorated, while the last 15 years come with prorated coverage.

The Sleep Number beds, on the other hand, tend to come with a 20-year limited warranty, which is only five years less than the Tempur-Pedic mattress warranty, and that does not make too much of a difference. However, what makes these two types of warranty so different is the fact that the latter does not protect the mattress against flattening of the comfort layer.

Also, given the fact that most Sleep Number mattresses are air chamber-based, the non-prorated and the prorated coverage period tends to vary as well. One common aspect that both manufacturers share is the fact that they offer users a limited trial period, and this comes in handy for most potential customers.

The Bottom Line in the Sleep Number vs. Tempur-Pedic Comparison

To conclude, both Sleep Number and Tempur-Pedic are reputable mattress manufacturers, and their products are designed to meet some of the highest quality standards set in this industry. In our Sleep Number vs Tempurpedic comparison we noticed there are several significant difference between the two companies, but generally, both of them make products that often rise – and even exceed – the expectations of their customers.

Researching Your Purchase

It is of utmost importance for every customer to do their own research before making their choice, and to decide on the type of mattress that best accommodates their needs. If you want a highly adjustable mattress easily adapted to your needs (for instance, if you plan to become pregnant you will need a different comfort and support level than you do now), then you should go with the Sleep Number air beds, as they are easy to adjust, they have an electric pump that does all the work for you.

On the other hand, if you want a sturdy and very long-lasting mattress that does not come with any of the common problems associated with mattresses these days (sagging, softening, deep body impressions and such), then the Tempur-Pedic mattresses may be the best for you. They do require a significant initial investment, but they are a great long-term choice as they offer great pressure point relief, efficient support, they promote a healthy and restful night’s sleep and they also aim to reduce the tossing and turning during the night.
