Sleep Number / Select Comfort Company Ratings

Warranty coverage D+ Sleep Number beds have a 25-year limited warranty, but owners overall give the warranty a below-average rating mainly because non-prorated coverage ends after the second year of ownership. See Sleep Number warranty details. Also see mattress warranties: what to know.
Return policy D+ Sleep Number's policy consists of a 100-day trial period which allows the customer to return the bed for an exchange or a 100% refund minus initial shipping and any setup fees. The customer is also responsible for return shipping fees as well as preparing the bed components for shipping. Competitor airbed brands often have somewhat superior return policies overall. As is often true for other brands, there are NO returns or exchanges for adjustable bases, closeout or demo bed models. (See returning a mattress: what to know.)
Customer service C- Historically, Sleep Number / Select Comfort customer service has been considered by consumers to be at least average. However, due to a company wide computer conversion, customer service quality fell dramatically in late 2015 but appears to be improving as of March 2016.
Marketing accuracy C- Sleep Number claims that "only the Sleep Number bed provides individualized comfort..." This is not true as competing airbeds provide this feature. The company also makes an uncited claim that 92% of owners would recommend Sleep Number. In addition, some claims regarding the softness and temperature coolness of their beds are not consistent with a significant number of owner experiences. Finally, at least 15% of owners feel misled by the 25-year warranty because non-prorated coverage ends after just the second year of ownership.
Specs and policies disclosed D+ The disclosing of specifications and general policies allows consumers to know what they are paying for and helps them to comparison shop. On their website, only the most basic mattress specs are provided. And warranty terms as well as 100-day trial details are not easily located.
Time in business B+ In business since 1987.
BBB rating A+ Select Comfort Corp., the manufacturer of Sleep Number beds, has maintained an "A+" Better Business Bureau rating for many years.
Number of BBB complaints D About 850 BBB complaints against Select Comfort Corp. have been filed in the past three years, 61% of them in the past year. This complaint number is more than triple that of other major mattress manufacturers. A large number of complaints are due to delayed delivery and poor customer service caused by a recent company computer conversion. The high complaint number is also due to the fact that Select Comfort – unlike other major mattress manufacturers – is the exclusive retailer of their mattress and therefore all complaints go to Select Comfort as opposed to being dispersed among independent retailers to a significant extent.
SLTD rating C- SLTD (Sleep Like The Dead) company rating of "C-" for Sleep Number / Select Comfort is determined by averaging the above company ratings.

Owner Satisfaction

Sleep Number beds overall have 77% owner satisfaction with satisfaction among the individual models varying somewhat. By comparison, all mattresses overall as a group (innerspring, air, memory foam, latex, water, futon) have 72% owner satisfaction.

sleep number owner satisfaction comparison


Prices / Value

The average Sleep Number mattress is 15% more expensive than the average permanent-use airbed and 38% more expensive than the average mattress regardless of type. (See all Sleep Number model prices.)

sleep number price comparison chart

The above price does not include maintenance costs that are often required to keep the mattress functioning properly. These costs can be substantial as non-prorated warranty coverage ends after just the second year of ownership. Also, the air pumps use electricity to operate and thus contribute to an owner's electricity bill.

Value

Most mattresses priced similar to Sleep Number are heavy in weight and are made with at least somewhat exotic materials. Sleep Number beds, by contrast, are fairly lightweight and are made mostly with relatively simple materials. This causes a significant number of owners to question the high price and overall value of the bed; the term "glorified air mattress" is often used by these owners to describe the bed.

The majority of owners regard their Sleep Number bed to be no better than a fair value. And at least 30% regard it as a poor overall value. In fact, Sleep Number bed owners question the value of their bed more often than owners of any other major mattress brand.

sleep number value comparison chart


Adjustable Firmness

Airbeds, including Sleep Number beds, are the only type of bed that provide instant firmness adjustment. At least 45% of Sleep Number bed owners praise their bed for this feature. However, finding one's ideal adjustment setting or "Sleep Number" can take considerable time and patience.

Adjustable firmness is well-liked by owners primarily for these reasons:

It must be noted that at least 15% of owners do not agree that a Sleep Number bed truly has adjustable firmness, that is, the ability to change from soft to firm or firm to soft. Instead, they say the bed has adjustable support, meaning that adjustment affects spinal alignment, not firmness levels. In other words, these owners say that a lower number does not feel softer, just flatter, and a higher number does not feel firmer, just more bulging.

Firmness Stability (Air Loss / Gain)

At least 12% of Sleep Number bed owners report that their bed loses air, either slowly or quickly. Faulty air pumps, loose connections, malfunctioning controllers and air bladder leaks are the most common causes of significant air loss. Air loss can result in reduced comfort and support and may even cause pain, including back pain. It can also result in less than restful sleep due to the owner needing to readjust the firmness throughout the night.

In addition, firmness settings can automatically fluctuate significantly in either direction, depending on temperature, barometric pressure, weight and sleeping position.


Durability and Longevity

With most mattresses, durability and longevity mean basically the same thing. But with the Sleep Number bed (and airbeds in general), these issues should be evaluated separately.

Durability

Mattress durability refers to how well a bed will hold up to regular use without something breaking or deteriorating. On this issue, the Sleep Number bed performs about average or worse compared to mattresses overall. This is largely because the bed, unlike other mattress types, is mechanical in some ways with many different parts and, as a result, more can conceivably go wrong with it.

At least 20% of Sleep Number bed owners report having over the span of ownership at least one durability problem – such as a leaky air chamber, broken air pump, malfunctioning controller, deteriorating comfort layer, bulging sides, compressed foam borders and failing edge support. Such problems can cause discomfort and undermine sleep quality.

The Select Comfort Mattress durability chart

Longevity

Longevity refers to the lifespan of a mattress. Sleep Number beds have better longevity than most mattresses in part because any problem that the beds develop can be repaired with a replacement part sent to the owner from Sleep Number / Select Comfort. Replacement parts can be not only mechanical parts, such as pumps and controllers, but also non-mechanical parts such as support foam and comfort layers.

By contrast, with other types of beds, such as innerspring mattresses, if something stops working properly or deteriorates, such as the spring system or comfort layer, the bed usually needs to be entirely replaced.

Of course, at some point during Sleep Number bed ownership, it will likely become cheaper to buy a new bed than to continue buying replacement parts.

As the chart below shows, owners overall report keeping their Sleep Number bed for about nine years, considerably longer than the average mattress.

Ease / Difficulty of (Initial) Use

Conventional mattresses are easy to use in that you simply lie on them and no adjustment is involved. By contrast, airbeds in general including Sleep Number involve a learning curve in that you must find which setting is right for you personally. At least 30% of owners say that significant time and effort was required to find their optimal setting or "sleep number."

Also, your preferred setting may vary depending on your sleep position requiring you to change the setting each time you change position.

select comfort ease of use chart


Level & Flat Sleep Surface (Middle Area)

About 20% of Sleep Number bed owners report a problem with the middle of the bed where the two air chambers meet.

Some owners say there is a "valley" or "trench" in the middle, while others report a "hump." There also can be a problem with one or both sides of the bed sloping toward the middle which can cause a sleeper to roll or slide in that direction.

The middle area may be uncomfortable to lie on, and it can be less than friendly for intimate activities, including cuddling, spooning and sex.

Sleep Number customer service may have solutions to problems with the middle, such as a "lift" which is a piece of foam that is placed under the air chambers to raise the middle.

Problems with the middle of the bed tend to be reported mainly by owners who use very different firmness settings for each side of the bed, such as 90-20. It may also be a problem when both sides use a very low or very high firmness setting.

It should be noted that the Sleep Number c4 model uses a design that may minimize any problem with the middle of the bed.


Maintenance Needs

Low maintenance is not a strength of airbeds in general, including Sleep Number, for the following reasons.

select comfort maintenance


Pain Reduction / Increase

Pain Reduction

For about 25% of owners, a Sleep Number bed relieves or even eliminates pain that one may feel both in and out of bed. Relief of back pain especially is commonly noted.

As the charts below show, Sleep Number beds perform better than the average mattress in regard to pain relief. Other mattresses – namely competing airbeds and Tempur-Pedic – may equal Sleep Number's ability to reduce pain, but none likely exceed it.

Among Sleep Number bed owners, back sleepers are most likely to report pain decrease.

Chart 2. Portion of OWNERS OF THE AVERAGE MATTRESS reporting back pain decrease, back pain increase or no significant difference either way.

Average mattress pain relief

Pain Increase

At least 10% of Sleep Number bed owners say that the bed causes discomfort or pain or makes preexisting pain worse, particularly back, shoulder, hip and joint pain. The chart below shows the top reasons owners give for experiencing pain on a Sleep Number bed.

Top Reasons For Experiencing Pain

Select Comfort Complaints / Problems chart

As the chart above shows, the main cause of discomfort and pain is excessive firmness as Sleep Number beds in general are considered to be more firm than soft. The Classic models and even Performance models are too firm for some people, especially side sleepers.

To deal with this problem, about 15% of owners, especially owners of the Classic Series models, add a mattress topper to their bed to improve comfort.

Air loss and the corresponding loss of support can also cause discomfort or pain. In addition, an improper setting can cause the sleep area to bow in or bow out which can put one's spine in an unnatural and uncomfortable position especially for side and stomach sleepers.

Other main causes of discomfort / pain appear to be mostly the result of the middle problem as well as a sagging comfort layer.


Noise

While conventional mattresses are often mostly if not totally silent, airbeds in general, including Sleep Number beds, can make some noise due mainly to the fact they use electric air pumps to adjust their firmness / support level.

While air pumps have become quieter in recent years, some owners (about 5%) still report that the pumps are loud enough that they cannot be used during the night without the risk of waking a sleeping partner. Pumps that are defective in some way may be especially loud.

In addition, Sleep Number beds may also produce a rustling, crunching, or squeaking noise when moved on, say about 7% of owners.

Break-In Period

Airbeds often have a shorter break-in period than other mattress types. Thinner, less expensive Sleep Number models tend to break in faster than thicker, more expensive models.

Sleep Quality

At least 30% of owners say their Sleep Number bed allows them to sleep better with less tossing, turning and restlessness. Some owners also say they sleep more efficiently on the bed, that is, they sleep more soundly and can spend less time in bed as a result.

Initial Odor

About 7% of owners say their Sleep Number bed has a significant odor when new. It is often described as a rubber or chemical-like smell. The problem tends to diminish within a week for most owners but can last longer in some cases.

Motion Isolation

While not a major strength, the Sleep Number bed (two air-chamber models) is for most owners at least moderately effective at localizing motion. In other words, movement made by a person on one side of the bed does not fully transfer across the bed to disturb another person on the bed. About 5% of owners, however, say their Sleep Number bed has poor motion isolation.

In addition, Sleep Number has made the following statement about motion isolation.

"Under certain circumstances, there might be motion detected (up/down) on one side of the bed if someone gets out. There is some lateral pressure exerted on the air chambers against each other where they meet. If someone gets out of bed, the occupied chamber now has more 'room' and will slightly expand to the center and cause a 'drop' for the sleeper. When the other person gets back in bed, it may cause that chamber to expand and press back against the other, causing a 'rise'."

Select comfort motion isolation


Sex Suitability

About half of the owners included in our research who commented on the issue say their Sleep Number bed is suitable for sex, or at least no less suitable than other beds. The other half say the Sleep Number bed is generally not good for sex because most models have a trench or intrusion in the bed's middle where the two air chambers meet. The c4's design, however, likely reduces this problem.

This trench or intrusion, they say, makes being in the middle of the bed uncomfortable and causes them to have sex on one side of the bed or the other which does not leave enough room. However, owner experience data suggests that the trench / intrusion in the middle can be minimized by having both sides of the bed set at a moderate firmness level such as 50.

Owners also report that the trench / intrusion in the middle may not allow them to spoon or cuddle with their partner comfortably.

Other airbed brands tend to not have this degree of middle problem.

Sleep Temperature

About 6% of owners overall report significant and bothersome heat retention, especially in summer months. Heat retention potential can vary by model.

By contrast, about 5% of owners report their bed sleeping cold, especially in winter months.

Sleep Number offers DualTemp – a layer designed to heat or cool each side of the bed – as well as a variety of temperature-regulating toppers and pads. Owner experience data on the effectiveness of these product is mixed. Learn about other temperature-control products.


Mold

No more than 3% of owners report finding mold in their Sleep Number bed, usually between the foam and air chambers. A small number of these owners report feeling ill because of the mold. Mold / mildew problems in a Sleep Number bed is a well publicized and discussed issue. However, the number of owners who have a mold problem – or at least are aware of having such a problem – is small based on our collected data involving over 1,700 owners.


Assembly

Sleep Number beds, like airbeds in general, require assembly. Most owners, but not all, say that assembly is easy and takes about 40-90 minutes depending on whether one or two people are involved.

Care should be taken with assembly as owner experience data suggests that poor assembly can cause the bed to not function properly and / or be uncomfortable. In fact, improper assembly may be a significant cause of owner dissatisfaction.

Upon delivery, for an additional fee, the bed can be assembled by professionals.


Weight and Ease of Transport

Sleep Number mattresses weigh 37-120 pounds depending on model and size making them less heavy than many conventional mattresses. Their relatively low weight is due mostly to the fact that they consist of air to a significant extent.

Their below-average weight, however, causes some people – namely those who associate low weight with cheapness – to question Sleep Number's mostly above-average price.

sleep number weight chart

The relatively low weight of the beds combined with the fact that they can be disassembled and broken down into individual components make them relatively easy to handle, lift, move, or transport.

select comfort ease of transport


Warranty

Sleep Number beds have a 25-year limited warranty.

Sleep Number bed owners overall give the warranty a below-average rating mainly because non-prorated coverage ends after just the second year of ownership. (Non-prorated coverage means that the customer pays nothing for repairs / replacement, while prorated means the customer pays partial cost.) Owners also tend to be disappointed that the warranty does not cover comfort layer deterioration and flattening – a somewhat common problem.

By comparison, other air bed brands often provide at least a slightly longer non-prorated period. And the brands of most other mattress types, such as innerspring and memory foam, often provide non-prorated warranty coverage for 10 years.

select comfort customer service

For more general information, see mattress warranties: what you should know.

Sleep Number Bed Warranty Terms

0-2 years after purchase No cost to owner for repair
3-20 years after purchase Owner pays 20% of repair costs plus 4% of repair cost for each year from original purchase date 
21-25 years after purchase Owner pays 96% of repair cost.

For the 3-20 year portion of the warranty, here is an example. You have a problem that costs $200 to repair and you've had the Sleep Number Bed for 10 years. You will pay 20% of the cost ($200 x 20% = $40) plus 4% of the cost times 10 years (4% x $200 x 10 = $80). So you will owe $120 ($40+$80) of the $200 repair cost and Sleep Number will pay the rest.

In addition, after the first two years you are responsible for all shipping costs related to any repaired or replaced product.


Adjustable Bases: FlexFit 1, 2 & 3

Sleep Number sells (non-returnable) FlexFit adjustable bed bases priced $1000-$4800. These bases can raise a person's lower and / or upper body making them generally effective at providing various health, comfort and convenience benefits. Sleep Number beds can be placed on most brands of adjustable bed bases, not only FlexFit.

The value of the FlexFit models are questionable given that less expensive adjustable beds with similar or better features are available. Learn how FlexFit models compare to the competition: adjustable bed base ratings.

* Sleep Position Rating indicates what tends to be true for owners; your personal evaluation may differ.

**
While firmness / comfort can be adjusted by adding or removing air, the general firmness of the bed is largely determined by the thickness and composition of the comfort layer which varies by model. A thicker comfort layer tends to be softer, a thinner one tends to be firmer.
