From their television commercials to their brick-and-mortar stores, Sleep Number is well-known in the mattress world. The company offers five mattress lines, as well as RV and kids mattresses, and they’re generally considered a stand-out in the adjustable air bed category.

We took a close look at their technology, company reputation, and customer feedback to bring you this comprehensive Sleep Number review.

In a sense, Sleep Number mattresses are just like any other: The top section is the comfort layer, while the bottom section provides support.

But instead of using layers of supportive foam or an innerspring system, the bottom portion of a Sleep Number mattress features an adjustable air chamber. It can be inflated or deflated to your preferred level of firmness.

Unfortunately, Sleep Number doesn’t disclose what the comfort layer is made of. Reviewers describe it as cushiony but not necessarily plush. Some Sleep Number mattresses have thicker comfort layers.

Sleep Number mattresses fall into the luxury mattress category. Website pricing for queen mattresses is $899 to $4,299, depending on the model. These prices don’t include optional upgrades, like regular or adjustable bases.

Sleep Number mattresses are generally comparable to other luxury mattresses. A queen-size Sleep Number 360 pSE Smart Bed with an adjustable base, under-bed lighting, and a foot-warming feature is $5,198 before tax and shipping. That’s about the same price as a Tempur-Pedic mattress with similar options and upgrades.

Pricing guide

Prices in this review are based on queen-size mattresses without optional upgrades or features.

  • $ = under $1,000
  • $$ = $1,000–$2,500
  • $$$ = over $2,500

The four Sleep Number mattress lines have a few different options. The more expensive option in each line features extra inches in the comfort layer and a higher overall mattress height. For this review, we looked at the less expensive option in each category.

All Sleep Number mattresses feature an air pump and a remote control to customize comfort by adding or releasing air. The firmness can be adjusted from 0 to 100 in increments of five.

There are optional upgrades, including a base that elevates the head and foot position on either side, a foot-warming feature, and under-bed lighting.

Sleep Number mattresses are available for purchase at any of the Sleep Number stores in the United States. You can also buy them on the company’s website.

These mattresses can’t be purchased at third-party mattress or furniture stores.

Height, comfort layer thickness, and cooling features are the biggest differences among the Sleep Number models. When choosing a mattress, think about how plush you like your mattress and if you’re looking for upgrades.

Sleep Number offers a sleep quiz to help you narrow your options. Nine questions cover the following:

  • who is using the mattress
  • your preferred mattress size
  • your ideal price range
  • your current quality of sleep
  • your preferred firmness level
  • if you sleep hot
  • how much you toss and turn
  • if you experience common sleep issues, like cold feet, trouble falling asleep, and snoring
  • if you read or watch television in bed

Based on your answers, the company offers several mattress recommendations that might suit your needs.

Visiting a Sleep Number store and speaking directly with a salesperson can also help you decide which mattress might work. You’ll also have an opportunity to try out the bells and whistles in person.

If you decide to shop on the company website, Sleep Number offers a 100-night trial so you can try your mattress at home.

Delivery and setup of most Sleep Number mattresses aren’t free, and additional fees may apply outside the company’s standard delivery area.

The company’s home delivery service costs $199 and is required on certain models. This service gives you the option of choosing a delivery date so your new mattress (and base, if you upgrade) can be fully assembled. Plus, they’ll remove your old mattress.

You may want to review Sleep Number’s delivery checklist before getting your new mattress delivered.

If you’re unhappy with your mattress and decide to return it, note that shipping and delivery fees are nonrefundable.

In general, Sleep Number has a positive reputation. The company is accredited with the Better Business Bureau and has an A+ rating.

Founded in 1987, the company’s mattresses are made in the United States, at manufacturing plants in South Carolina and Utah.

Sleep Number hasn’t been involved in any recent lawsuits related to consumer safety. However, in 2017, the company did recall the foot-warming accessory on certain models due to concerns of overheating.

Because Sleep Number mattresses can only be purchased through their stores and website, the company has a lot of control over published reviews. That’s worth keeping in mind when you browse the thousands of positive reviews on their website.

On Trustpilot, a third-party review site, Sleep Number has an average rating of 1.6 out of 5 stars based on over 35 reviews. The company hasn’t claimed their profile on this website, and reviewers don’t clarify which mattress they own.

Many of the 1-star reviews on Trustpilot relate to poor sleep and negative customer service experiences, while the 5-star reviews praise the comfort and quality of Sleep Number mattresses.

Sleep Number offers a 100-night trial that begins the day your new mattress arrives. The company asks that you give yourself 30 nights to adjust to your new mattress.

If you’re not happy after 30 nights and before the 100-night trial ends, you can contact the company to arrange a return or exchange. This is a necessary step, as Sleep Number must authorize all returns. Some accessories, including bases, can’t be returned.

Shipping and delivery fees apply for any permitted returns. In some cases, the only available return shipping option may mean the product is picked up by Sleep Number at your cost. Returns can’t be processed in retail stores.

Sleep Number mattresses have a 15-year limited warranty against defects in material and workmanship under normal use. If you have a claim during the first warranty year, you don’t have to pay for repairs, but you may be responsible for shipping fees.

Costs go up significantly after the first year. Through year 11, you’re responsible for paying 30 percent plus 5 percent for each year from the date of purchase if you have a claim. From year 11 to year 15, you’ll pay 85 percent of the costs if you have a claim.

Warranties vary for Sleep Number accessories.

What makes a Sleep Number mattress different?

Sleep Number mattresses are air adjustable. That means they have air chambers inside the mattress that you can inflate or deflate on command. Each side can be adjusted separately, so if you sleep with a partner, each of you can customize your side with your preferred firmness level.

Is a Sleep Number mattress worth the price?

Sleep Number mattresses are pricier than many nonadjustable mattresses. You’ll pay about $899 to $4,299 for a queen-size mattress.

Still, many reviewers seem to feel that they’re worth the price. Happy customers report that they love being able to adjust the feel of the mattress just to their liking.

Can a Sleep Number mattress help with back pain?

Many reviewers say that their Sleep Number mattress helped alleviate back pain. Additionally, research from 2015 suggests that a medium-firm, self-adjusted mattress provides the best comfort, sleep quality, and spinal alignment.

How long do Sleep Number mattresses last?

According to Sleep Number, the mattresses should last at least 15 years. However, your mileage may vary. Some reviewers say the mattress lasted them about 10 years, while others say they’ve had their Sleep Number for 20 years. Other reviewers report that the mattress didn’t last them very long at all and that they experienced sagging issues.

Sleep Number is a well-known mattress company in the adjustable air mattress category. It may be ideal if you share your bed with a partner and you both have different comfort and firmness preferences.

Thousands of reviewers share glowing feedback about Sleep Number mattresses, but many of these customers opted for upgrades that vastly increased the cost of the mattress.

If you’re curious about what an adjustable air mattress feels like, Sleep Number has hundreds of stores across the United States.

The company also offers a 100-night sleep trial if you decide to buy online. But keep in mind that you’ll likely need to pay return shipping fees if you decide Sleep Number isn’t for you.
