With its unique five zones of contouring support, innovative comfort adjustments, and advanced Sleep IQ Technology, this mattress ranks with a 77% owner satisfaction rating as revealed in our research.

What type of Mattress is the Sleep Number P5?

the sleep number p5 mattress in a nice roomThe Sleep Number P5 is an airbed/foam mattress developed and manufactured with a 2” PlushFit foam layer, five zones of contouring support and soft, breathable knit fabric that keeps the mattress feeling and looking like new, year after year.

The Sleep Number P5 provides instant firmness adjustment, typical of all airbeds, an 11” profile, and delivers a true balance of softness and pressure point relief which contributes to the owners restful night’s sleep.

How Firm is it?

Unlike typical foam mattresses and other mattresses available on the market today, the Sleep Number P5 mattress is equipped with instant firmness adjustment and individual Sleep Number Settings that allow sleepers to select and set their own levels of firmness or softness.

Each partner can choose their required levels of firmness and softness, as well as comfort and support, and can change their settings at any time they choose, even in the middle of the night.

The individual settings allow sleepers to enjoy a comfortable, supportive and restorative night’s sleep.

In addition, the adjustable firmness results in better comfort for sleepers as well as reduced pain and pressure point relief.

With independent air chambers on each side of the bed, two people with different preferences for firmness can still sleep comfortably and peacefully together all night long.

Our data revealed that nearly 45% of all Sleep Number bed owners favor the adjustable firmness feature, but admit that finding the perfect ‘Sleep Number’ is not only challenging but quite frustrating and takes a great deal of time and patience.

One important note of concern, according to our data, is that at least 12% of Sleep Number bed owners reported that their beds lose air because of faulty air pumps, malfunctioning controllers, leaks or loose connections.

This has proven to be quite an issue with the Sleep Number P5 model as well.

With the air loss, consumers complain of reduced comfort and minimized support, and even increased pain resulting in a very restless and uncomfortable night’s sleep.

How many Layers does it have?

The 2” PlushFit foam layer offers a consistent comfort to sleepers of all weights and sizes.

The instant firmness adjustment has fast become one of the most recognized and valued features of the Sleep Number P5 and other Sleep Number models as well.

The ability to select, adjust and set your own levels of firmness or softness, along with individual levels of comfort and support set the Sleep Number beds apart from those of their competitors.

How is Motion Transfer and Sinkage?

The Sleep Number P5, like many other air beds, absorbs motion, but is not a major strength of Sleep Number beds.

Movement made by one partner on one side of the bed will not cause disruption on the other side of the bed nor interfere with your partner’s sleeping.

However, our data did reveal that about 5% of Sleep Number bed owners said their beds had poor motion isolation and poor motion transfer issues.

Does it Sleep Hot?

Like many memory foam mattresses, the Sleep Number P5 tends to sleep a bit warm, especially in the warmer summer months.

Our research revealed that approximately 6% of Sleep Number P5 owners reported significant heat retention, especially in the summertime and reported their bed sleeping cold in the brisk winter months.

The data also indicated that the potential for heat retention varies from Sleep Number model to model.

Does it have any Smell?

The Sleep Number P5 does have a noticeable rubber-like, even chemical-like odor when new. The odor tends to diminish after a couple of weeks.

However, our research revealed that some owners indicated that after extended periods of time the odor was still ever present.

Does it Require a Foundation?

The Sleep Number P5 is specially designed to be used with a solid base in order to ensure adequate support.

Base options for your Sleep Number P5 mattress include platform beds, a Sleep Number Modular Base, or a Sleep Number FlexFit Adjustable Base.

When choosing your base option the company highly recommends you do not use a traditional box spring base or a bed frame designed with slats since neither will provide sleepers with adequate support and comfort.

What type of Cover does it have?

a corner of the P% mattressThe Sleep Number P5 comes with a plush, breathable knit fabric cover that is simple to clean and maintain.

When washing your cover or attempting to remove stains, simply use a mild detergent and sparkling water.

Rub the fabric gently with slight circular motions from the outside, inward. Never use any type of bleach or chemicals on your P5 cover.

What is the Best Way to Care for the Sleep Number P5 Mattress?

The Sleep Number P5 is a no flip mattress.

Rotating and flipping the comfort layer and the foam components of the P5 multiple times per year is typically required to prevent it from sagging and to maintain and maximize its long life span. 

As for typical cleaning of the mattress, using cool sparkling water and a mild soft detergent is all that is required, as well as a gentle rubbing and circular motions.

Do not machine wash or dry clean the cover since this will cause shrinking and damage.

In addition, do not saturate the cover or mattress or use any type of a stain guard which will result in heavy discoloring.

What about Durability?

The Sleep Number P5 mattress is manufactured right here in the USA.

Data available to us during our review revealed that the Sleep Number P5 performs only slightly above average or even worse when compared to mattresses overall.

Unlike most other mattress types, Sleep Number Beds, including the Sleep Number P5 airbed/foam mattress is constructed with mechanical components, including an air chamber, air pump, and controller that can either break down, leak, or malfunction thereby minimizing the durability of the mattress.

Our research revealed that at minimum, 20% of owners reported having at least one major durability issue throughout ownership resulting in discomfort, lack of support, and poor sleeping results. 

Size and Shipping

The Sleep Number P5 mattress comes in a wide range of sizes, including Twin, Twin Long, Full, Double, Queen, King, California King, Split King, FlexTop King, and FlexTop California King.

Easy to lift and maneuver, the weight of the mattress is dependent upon the model and size, but will weigh in between 37 and 120 pounds.

Sleep Number stores offer free shipping for all their Sleep Number beds and, upon delivery, for an additional charge, your Sleep Number P5 can be assembled by the professionals.

100 Night Risk-Free Sleep Trial and Guarantee

If within the 100-day trial period you find you are not satisfied with the mattress you can return the mattress for a full refund. However, customers must pay the return shipping charges.

This 100 night risk-free trial affords consumers ample time to try out and experience the mattress.

If you discover you are not completely satisfied with your Sleep Number P5, give a call out to the company and they will make return shipping arrangements with a cost incurred to the customer.


The Sleep Number P5 presents with a 25-year limited warranty.

However, our research revealed that P5 owners give the warranty a below-average rating primarily because the non-prorated coverage ends after two years of ownership which tends to be the case with all the Sleep Number beds.

With that said consumers are giving the Sleep Number P5 warranty a below-average rating overall. 

How much does the Sleep Number P5 Mattress Cost?

The Sleep Number P5 ranges in prices from $1,699.98 to $4,999.98 depending upon the size of the mattress.

Additional charges apply if you choose to order one of the specialized bases made specifically for the Sleep Number beds.

  • Twin mattress $1,699.98
  • Twin XL $1,899.98
  • Full/Double $2,199.98
  • Queen $2,299.98
  • King $2,899.98
  • California King $2,899.98
  • Split King $4,999.98
  • FlexTop King $4,999.98
  • FlexTop California King $4,999.98

This mattress does not fare very well in comparison to other memory foam mattresses and other mattresses overall, especially in light of the high cost.

Overall, not a very good buy for the money. Currently there is a $400 discount coupon available for purchase of any size Sleep Number P5 mattress.

Sleep Number P5 Airbed/Foam Mattress Review – Our Verdict

Sleep Number P5, though rated as the ‘best bed for couples’ by a consumer magazine, offers a relatively average product for a high cost.

the sleep number p5 in a bedroomThough it is equipped with five zones of contouring support, a unique air chamber design, and both Sleep Number settings and a unique Sleep IQ Technology, the Sleep Number P5, like most Sleep Number mattresses, has been the target of many consumer complaints.

A sagging middle area of the bed and varied component breakdowns and malfunctions being the most common complaints, as well as the difficulty in actually finding your optimal ‘sleep number’ setting, all contribute to a fair price/fair value mattress rating by many consumers.

In addition, our research revealed that the Sleep Number P5, as well as other Sleep Number models allow mold and mildew to form on the convoluted foam topper and even on the air mattresses making the product quite unhealthy for people who suffer from mold/mildew allergies.

Overall, we think the Sleep Number P5 airbed/foam mattress is, as consumers suggest, a fair value, fair price mattress.
