The Sleep Number 360 Smart Bed Classic Series
The under-$1,500 Classic Series is Sleep Numbers entry-level offering, and the mattresses in this line sure feel like it. The 8-inch c2 reminds me of a dormitory bednot surprising, since it contains only 2 inches of foam the rest of the mattress is made up of air encased in the bladder. The c4 has an inch more foam, for a total of 9 inches, and feels only slightly less institutional theres nothing cuddly about it. Unless youre used to sleeping on a mat or you plan on springing for a good mattress topper, we dont recommend this series.
In 2020, Sleep Number updated its 360 Smart Beds, adding temperature-balancing featuresincluding high air-flow fabrics and gel materialsmeant to make the mattresses feel cooler and more breathable.
Making Sense Of Sleep Number
Sleep Number offers two lines of mattresses: the Sleep Number 360 Smart Bed line and the Sleep Number Value Bed line.
The Sleep Number 360 Smart Bed line consists of four series, most of which include several models:
From a design standpoint, Sleep Number 360 Smart Beds and Value Beds are similar to any other mattresses: Each contains an upper comfort portion made of foam layers and a lower support portion. Instead of the foam or springs found in the lower support portion of conventional mattresses, in Sleep Number mattresses, that support portion consists of an adjustable air chamber and a support pad. These air chambers make it possible for couples to independently adjust firmness levels to their own liking. Theres also a sleep tracker inside the bed.
Heres how the key components work:
The air chamber allows you to adjust the firmness level of the mattressyour sleep settingsby filling the chamber with more or less air. The settings range from 5 to 100 you can adjust them in increments of 5 using the SleepIQ app on your phone or tablet, or with a remote . With the 360 Smart Beds, the tissue-boxsized pump is incorporated into a base , which pairs with the mattress. If you dont purchase the base, the pump will sit on the floor.
The Sleep Number Innovation Series
The Innovation Series is Sleep Numbers highest-end, plushest line. Although these mattresses arguably dont feel as plush as most foam or innerspring mattresses of similar price, the beds in this line actually feel like nice mattresses. If I were set on a Sleep Number mattress and could afford to do so, Id spend more for the Innovation lines added cushioning. But for someone like my husband, who just wants something adjustable and comfortable enough to sleep on, a less-expensive p6 would do just fine.
The i8 comes with 6 inches of foam and a temperature-balancing surface , and it felt pleasantly pillowy. The i10, with its additional inch of foam, was just a tad fluffier. Like the pSE from the companys Performance line, the iLE is not a typical fixture in-store, and it, too, has the ClimaTemp foam, described by the company as softer and more cooling.

Delivery Warranty And Returns
The Value Bed line ships free via UPS. Other lines can be delivered in-person for $200. You can pick a day and time window based on availability, and, if all works well, Sleep Numbers Comfort Service Home Delivery service team stops by with your mattress, configures the air pumps and app, and shows you how everything works. However, the delivery team missed my window twice because of New York City traffic . I received my bed on the third try, only to find out that I had been given a one-chamber instead of a two-chamber mattress, as requested. For my re-order, with the help of the Sleep Number public relations team, I was able to confirm a morning delivery and received the correct mattress without a hitch. To be fair, despite my experience, customer service wasnt a big pain point among the user reviews we analyzed.
Theres a 100-night free trial for all new Sleep Number mattresses, but you need to sleep on one for 30 nights before filing for a return. Plus, if you decide to return the mattress, theres at least a $200 fee to cover transportation costs. If you ordered an adjustable base with your mattress, that base cannot be returned.
What To Look Forward To
In 2022, Sleep Number is releasing its Climate 360 Smart Bed, which is said to be responsive to both temperature and firmness preferences. The company says the bed will have sensors to measure sleep-tracking data like your heart, heart-rate variability, and breathing rate. Among other features, the mattress will automatically adjust firmness in response to your movements, and warm or cool the bed based on your body temperature. Sleep Number also now offers a kids bed.

The Sleep Number Cooling Memory Foam
The m7 is the only Sleep Number bed that offers the hugging sensation of memory foam. If you and your sleep partner prefer a light memory-foam cradling, and if you cant agree on a firmness level, then the m7 may be a worthwhile, albeit expensive, option. However, the company doesnt divulge what, exactly, is in that foamy comfort portion, so we dont know how dense, and therefore durable, it is. The sinky-ness of the m7 is comparable to that of most online foam mattresses . It has a slight sinking sensation, but not the more-assertive curve-conforming feel of something like the Tempur-Adapt.
The Sleep Number 360 Smart Bed Performance Series
The Performance Series is slightly plusher than the Classic Series. The p5 and cooling pSE each have 4 inches of cushioning, for a total height of 10 inches. The p6, the companys most popular mattress, has an additional inch of cushioning, for an overall thickness of 11 inches.
Compared with the beds in the Classic line and the Performance lines p5, the p6 felt like a real mattress, the kind with a surface thats adequately cushioned for people who are not particularly high-maintenance. But when I tried the p6 at home, I couldnt shake the feeling that I was sleeping on a rubber raft. The 5 inches of foam wasnt enough for me to nestle into, even with a softer air-bladder setting. Letting out air offered more give, but then the bed didnt feel as supportive, and it still didnt feel fluffy, per se.
I was left feeling adrift, but my husband, by contrast, loved sleeping on the p6. For once, instead of compromising on my medium-soft-mattress preferences, he could sleep on a firm mattress next to me. It was a sad day for him when we returned this mattress.
The pSE wasnt available to try at the store when I visited, but Sleep Numbers publicist said it has proprietary ClimaTemp foam that is softer and more plush than whats typically used on the p series. Unfortunately, were not sure exactly how this technology works because Sleep Number doesnt share details about its foam.

Going with the C2 and adding my own bells and whistles
Very grateful for Candid Reviewer’s advice. We were interested in the C2 after seeing the excellent rating it received from Consumer Reports, with high marks for durability, side and back sleeping. We went to the sleep number store, stuck to our plan and avoided being up- sold, and bought both the recommended fiber topper and a gel topper to experiment with once the C2 arrives. We also are using our old metal frame with a queen-size bunkie board , for a nice savings compared to the $300 foundation from sleep number. More $ for new sheets and bedding!
Not perfect but best mattress I’ve had in….well ever.
I will not buy any other bed again.
Best bed I ever had. I’m a big person 300 Plus pounds…At year 10 the pump went out and I called…they still had my info and sold me a new pump at 1/2 price. It’s went through 2 moves and is still great! My husband is also big so it stands up to heavy folks. Folks on the phone were friendly and helpful. I’m looking now to buy my son one.
So far, So Good!

Sleep Number Mattresses: An Honest Assessment
Weve updated this guide with information on new temperature-balancing features in Sleep Numbers 360 Smart Bed line and the forthcoming Climate 360 Smart Bed.
Spending thousands of dollars on a mattress that, by volume, is mostly air may sound as ridiculous as paying inflated prices for bottled water. But with some marketing magic and a few enticing extras, real or imagined, anything can happen. Sleep Number, the most successful brand in the adjustable air-bed category, offers 11 models with varying levels of cushioning, all of which can be puffed up to your desired firmness level with just the touch of a button. If you sleep alone and have a consistent firmness preference, Sleep Number is an overpriced option. But for couples with vastly different tastes in mattress firmness, those adjustable, air-filled chambers could be worth it.
How Sleep Number Mattresses Compare
The low end of each price range refers to the size noted in the chart. The high end refers to a split or flextop California king bed, unless noted. Split and flextop mattresses are the same pricea split mattress works for a base that adjusts only the upper body a flextop works for one that adjusts to both upper and lower bodyand theyre around $200 to $600 more expensive than a regular mattress of the same size.

The Sleep Number Value Beds
The Value Bed line is Sleep Numbers bed in a box option. The company is planning to discontinue it in the near future, but for now, given the current coronavirus crisis, it has gained in popularity because of its contact-free delivery. The Value lines s1 and the s3 mattresses cost about the same as the beds in the Classic line, but they have a quilted cushion layer . That quilted layer is zoned to cater to various pressure points there are five different cushioned areas in the s1 and seven in the s3. The company doesnt divulge details about its foam, so were not sure how the zones differ. But we do know that this comfort portion isnt thicker than the 2 inches we found wanting in the Classic lines entry-level c2, and the air pump sits on the floor, as opposed to being integrated into the mattress itself, like with the other lines. And although the Value line comes with SleepIQ technology, the Value Beds dont have the smart feature that allows them to conform to your body as you shift positions. We havent tried this line, but given how spartan the c line felt, we cant imagine that any amount of quilting or zoning would compensate for the thin comfort layer.
Is Sleep Number The Best Mattress
Sleep Number is one of the most well known mattress brands and has good scores from customers on initial comfort with its number firmness technology. However, there are some complaints about durability on the electronics, pumps, and air technology, which cause customers concern about value over time.

What We Think About Sleep Number Mattresses
In general, we think you can get a more comfortable mattress for a lot less. But if you insist on Sleep Numbers adjustability because you and your partner cant compromise on a firmness level, and you have a flexible budget, we think only the Performance Series and Innovation Series mattresses and the Cooling Memory Foam mattress are worth considering. The less expensive Classic Series mattresses and the Value Bed lines are just too thin for most people. If you like a plush mattress with good support, then you should spend more for the Innovation Series beds, which have thicker cushioning.
Beyond SleepIQ, Sleep Numbers marketing also touts technology that claims to help you fall asleep faster with a foot-warming feature. You can also theoretically control your partners snoring by raising the upper portion of their side of the bed. However, these features are available only with the companys adjustable bases , which cost between $1,200 and $2,400 for a queen.
Heres how the mattresses themselves compare to one another:
Owner Review Feedback For Sleep Number Mattresses
Sleep Number mattresses are typically purchased directly from Sleep Number, so thats where we found the majority of the online reviews. Out of the 34 good-quality negative user reviews we collected about the Classic Series , 10 contained complaints about issues related to a lack of cushioning. This included reviewers describing the mattress as too firm, too thin, bottoming out, or having poor pressure relief. Several reviewers pointed out that the c series is especially problematic for heavier-weight sleepers, and others noted the support felt better once they added a mattress topper.
For negative feedback on the Performance Series, we found far fewer complaints related specifically to the mattress thinness . But four out of 26 good-quality negative Innovation Series reviews noted that the mattresses were too firm or offered poor pressure relief. Perhaps this is to be expected, given that these users paid much more for their mattresses and therefore expected more. Three out of the six Cooling Memory Foam owners complained that their mattresses were either too thin, too firm, or lacked pressure relief.
