* The Memory Foam series models currently have a small, statistically insignificant sample size due mainly to the fact that they are fairly new to the market. Ratings are based on this limited sample as well as the estimate of the Sleep Like The Dead editor.


Owner Satisfaction

Sleep Number beds as a group have 78% owner satisfaction (78 out of 100 based on 1652 reviews). The Innovation series models tend to rate slightly higher than the Classic, Performance and Memory Foam series models.

By comparison, all mattresses overall as a group (innerspring, air, memory foam, latex, water, futon) have 72% owner satisfaction.

Durability and Longevity

With most mattresses, durability and longevity mean basically the same thing. But with the Sleep Number bed (and permanent-use air beds in general), durability and longevity can and 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 all mattresses overall. This is largely because the bed, unlike other mattress types, is mechanical in some ways 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 of some kind – such as a leaking air chamber, broken pump, or malfunctioning controller.

The Select Comfort Mattress durability chart

Longevity

Longevity refers to the lifespan of a mattress. The Sleep Number bed has better longevity than most mattresses in part because any problem the bed develops 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.

Another reason the Sleep Number bed has above average longevity is due to the fact that it uses air to support the sleeper. Air, unlike springs or foam, cannot compress and breakdown with age and wear.

Ownership length

The ability to replace any part of the Sleep Number bed, and the relative ease by which it can be done, can result in significant length of ownership. Owner experience data, in fact, shows the bed to have one of the longest life spans of any mattress.

The graph below shows that owners on average report keeping their Sleep Number bed for about ten years. Some owners keep the bed for considerably longer than ten years and some for considerably less time.

Sleep Number Bed Complaints / Problems

Below are the main disadvantages and problems of the Sleep Number bed as reported by actual owners.

sleep number bed complaints
                                                  Percent of owners reporting problem

Complaint #1: The Middle

The c3 and c4 models now use an "edge-to-edge" design, one similar to that used by many Sleep Number competitors. This design likely reduces or even eliminates any problem with the middle of the bed.

Other Sleep Number models may in the future receive this new design as well. Until then, however, the following applies to the other models.

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 Sleep Number bed tend to be reported mainly by owners who use very different firmness settings for each side of the bed, such as 80-20. By contrast, owners who use more similar settings for each side tend to not report the middle as a significant problem.

Complaint #2: Price and Value

At least 18% of owners, especially owners of more expensive models, complain about the price they paid. Indeed, prices for the top-of-the-line Sleep Number models are about twice that of the average mattress.

sleep number price comparison

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 with relatively simple materials. This causes a significant number of owners to question the high price and overall value of their bed; the term "glorified air mattress" is often used by these owners to describe the bed. In fact, Sleep Number bed owners question the value of their bed more often than owners of any other mattress.

Complaint #3: Air Loss (Or Gain)

At least 12% of Sleep Number bed owners report that their bed loses air, sometimes slowly and sometimes quickly. Faulty air pumps, loose connections, malfunctioning controllers and air bladder leaks are the most common causes of 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.

Complaint #4: Causes Discomfort / Pain

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 less expensive Classic Series models, especially c2 and c3, are firmest due to their minimal padding.

About 10% of Sleep Number bed owners, especially owners of the Classic Series models, report adding a topper to their bed, usually a memory foam topper, to improve comfort. Most of these owners report success.

Another cause of discomfort / pain may also be the use of a firmness setting that is not well suited for one's sleeping position. For example, while a softer setting may be appropriate for back sleep, such a setting may be inappropriate for side and stomach sleep as it may cause a person's midsection to bow in, resulting in unnatural spinal alignment.

Complaint #5: Compression & Flattening of Top

Around 10% of Sleep Number bed owners report that the foam around the edges of the bed and or the pillow top sags, compresses or develops body impressions. This can cause discomfort and undermine sleep quality, say owners. (This is likely not a problem with the current c3 and c4 models as they use a design which eliminates edge foam.)

Some methods can be effective in rejuvenating a Sleep Number bed pillow top such as using a vacuum hose to puff it up, taking the top off the bed and shaking it, or putting the top in a large dryer.

If such methods are ineffective, however, the pillow top will need to be replaced. Some owners purchase a new top from Sleep Number, while others replace their top with a mattress topper purchased from an independent retailer, often at a lower price.

The Innovation Series models with their thick pillow tops have the most complaints regarding compression / body impression development; the Performance series models with their moderately thick tops have fewer complaints; and the no-pillow top Classic Series models have the fewest complaints.

Complaint #6: Noise

While most mattresses are generally silent, air beds in general, including Sleep Number beds, can make significant noise because they use electric air pumps to adjust the firmness level.

Even though the air pumps are touted to be "whisper quiet," as many as 10% of owners 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.

Sleep Number Bed Advantages / Benefits

Below are the main advantages and benefits of the Sleep Number bed according to owners.

sleep number bed complaints
                                         Percent of owners reporting advantage / benefit

Advantage / Benefit #1: Adjustable Firmness

Air beds, such as the Sleep Number bed, are the only type of bed that provide instant firmness adjustment. At least 30% of Sleep Number bed owners praise the 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 should be noted that about 10% 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. These owners say that a lower number does not feel softer, just flatter.

Advantage / Benefit #2: Improves Restful Sleep

At least 20% of owners say their Sleep Number bed allows them to sleep better with less tossing, turning and restlessness. They often say that a lack of significant pressure points is the main reason for their improved sleep. 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.

Advantage / Benefit #3: Pain Reduction

For at least 20% of owners, a Sleep Number bed relieves or even eliminates pain that one may feel both in and out of bed. Relief of back, shoulder, hip and joint pain are commonly noted.

As the charts below show, Sleep Number beds perform better than the average mattress in regard to pain relief. Other mattresses, such as Tempur-Pedic, may equal a Sleep Number bed's ability to reduce pain, but none exceed it.

Chart 1. Portion of Sleep Number bed owners reporting pain decrease, pain increase or no significant difference either way.

Advantage / Benefit #4: Motion Isolation

For most owners, especially those who previously owned an innerspring mattress, the Sleep Number bed does a fair to good job in 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. These owners are almost always people who previously owned memory foam or latex mattresses which have superior motion isolation. Consistent with this fact, the Memory Foam series models likely have somewhat better motion isolation than the other Sleep Number bed models.

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'."

Advantage / Benefit #5: Pregnant Friendly

Pregnant women as a group rate Sleep Number beds higher than other beds. They say the beds' adjustable firmness and good supportiveness generally help to relieve some of the difficulties that come with pregnancy.

Love Making 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 not good for sex overall because most models have a trench or intrusion in the middle where the two air chambers meet.

This, 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 each side of the bed set with the same firmness level.

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

For more information see the mattress and sex comparison.

Assembly

Sleep Number beds, unlike most other beds, 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.

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 1,650 owners.

Weight

Sleep Number mattresses weigh 37-90 pounds making them no heavier than many conventional mattresses. Their limited weight is due mostly to the fact that they consist of air to a significant extent. As a result, the beds can be relatively easy to move, transport, handle and lift. Their weight, however, causes some people, namely those who associate lower weight with low cost, to question the above-average price of the beds and their value.

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 compression 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 10-15 years.

For more 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.

Return Policy and Trial Period

Sleep Number's return policy consists of a 100-day trial period in which if you do not like the product you can send it back for an exchange or 100% refund minus initial shipping and any setup fees. (There are no returns or exchanges for adjustable bases, closeout or demo bed models.)

Sleep Number bed owners overall give the return policy fair-to-poor ratings. Owners like the trial period but do not like that they must pay return shipping if they send it back. Competitor air bed brands usually have less costly return policies. (For more information, see returning a mattress: what you should know.)

* Firmness. 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. In addition, keep in mind that medium to firm tends to be suitable for back sleepers; medium for stomach sleepers; medium to soft for side sleepers. Also, the firmness descriptions above indicate what tends to be true for most owners; your individual evaluation may differ.
