Sleep Number C2 Review (2021) – Best/Worst Qualities

The material: The mattress itself is made from a blend of Rayon and polypropylene fabrics, and is eight inches thick.

    • The cover: Part of the reason c2 is more basic than other Sleep Numbers is because there is no foam mattress pad on top of the air chamber. (All other Sleep Number mattresses come with a Comfort Foam layer.) Instead, the c2 has a soft fiberfill sewn into a thin layer right above the air chambers. This top layer of the mattress has a zipper, so technically is removable, though it’s not recommended you wash it (this will result in shrinking and permanently damaging your cover.) Instead, try spot cleaning any stains with a mild detergent.
    • Air chambers: Every Sleep Number mattress comes with one or two air chambers depending on what size you have. Beds starting at a Double size have two chambers. This is where the magic happens! These air chambers connect to a pump that can inflate or deflate your mattress, depending on your Sleep Number setting. Sleep Number calls this their “DualAir technology.” The hose to pump air into the chamber is four feet in length and is cleverly hidden inside the bed. Just unzip the removable cover to access it. The air chambers themselves are made of 24 gauge vulcanized rubber with a cotton fabric adhered to the exterior through a heat treating process. However, a handful of reviews complained of a rubber smell from the air chamber. According to Sleep Number, the odor is non-toxic and will quickly fade; one way to help is unzipping the mattress cover so the air chamber can air out for a few hours.
    • The technology: Since this isn’t your average mattress, be prepared to juggle a few accessories in order to use this bed properly. The first one is Sleep Number’s Firmness Control™ System, which encompasses the remote, air pump, and hose(s). (Make sure there’s an electric power source nearby to operate your Firmness Control™ system.) The remote should come with a 9 volt battery; there is a simple up and down arrow for you to click to adjust your Sleep Number setting. If you have a dual chamber bed, there will be two hoses that you will need to pass through the opening of the mattress cover to connect the hose to the air chamber. Each hose will either say L or R (left or right) to indicate which hose is for which side of the bed. (Right is indicated as though you are lying on your back on the bed, looking toward the foot of the bed.)
    • Sizes: The c2 mattress comes in 10 sizes, ranging from Twin to Flextop California King. Continue reading to see all of the sizes and subsequent prices.

Sleep Number is a bedding company that sells bed, mattresses, and various bedding products. However, the company is best known for its signature product, the Sleep Number bed, which comes with an adjustable air mattress and various add-ons like a smart system, adjustable bases, and different types of comfort foam mattress pads.

Sleep Number c2 Mattress Feel

The c2 mattress is on the firm end of the Sleep Number spectrum, mainly because it does not come with a Comfort Foam cover. Another way to understand firmness level is by looking at the model number. The higher the number, the more more cushion/thicker layer each mattress will have. (So, c2 is the firmest and the 1-10 model has the most cushion, with a 4” layer of foam atop the mattress. The c4 version will be the bed closest in firmness and feel to the c2.)

However, reviewers and testers have noted if you like things on the softer end, you can might consider buying a separate mattress pad to add some additional cushioning if you prefer a softer or more plush sleeping surface.

If you share the bed or just find yourself rolling over to the edge, the c2 ensures you’ll be supported well and won’t feel like you’re about to fall off. That’s because the c2 is also known for having great edge support due to four foam border walls that are part of the bed. (Yes, there is some assembly required with these foam pieces if you decide to set up your bed yourself.) Typically, Sleep Number and air beds are known for having better edge support versus memory foam and latex mattresses because of these foam walls.

A handful of customers also spoke about c2’s motion transfer. They said the bed does a good job at feeling sturdy and stable—aka it has little motion transfer—so you’re less likely to be bothered if your partner tends to toss and turn at night. For some comparison, memory foam mattresses also do a great job of transferring little motion, while beds that have flexible coil springs in their box spring are the most known for having motion transfer issues.

Sleep Number c2 Mattresses Vs. Others

Speaking of, how does a the Sleep Number c2 compare to other types of beds? What is it really like to sleep on air rather than metal coils, foam, or springs?

Perhaps the biggest perk and differentiator of the c2 is you can easily adjust the support level, thanks to the air chamber within your mattress. Still, even with a lower Sleep Number, this specific model will be super firm because there is no foam cover. Expect a dense feel with little bounce and motion transfer that will keep your body in place.

This will feel different from mattress like Casper, that has a medium-firmness and a decent amount of bounce due to its springy comfort layer, or a Tempurpedic bed, that provides great pressure support due to the qualities of memory foam. Note: Sleep Number beds feel very different from memory foam (which are softer and naturally made to adjust to the contours of your body) so if you know you love memory foam, consider buying a memory foam topper for the air bed.

Also, don’t forget that the Sleep Number comes with some assembly, and there is always a risk for tech issues or air loss (sudden changes in external air pressure, like temperature or high altitudes, can soften the bed). If you don’t want to walk into or worry about any complications in the bedroom, Sleep Number might not be a great choice.

Sleep Number: What’s Yours?

When I chatted with a Sleep Number employee online to ask her a few questions, she introduced herself with her name and her Sleep Number. (32, if you were wondering.) And that’s one thing that no other type of mattress will come with: a personal number.

The “Sleep Number” refers to the level of firmness your bed will be, depending on your sleep preference. This number will range from 0-100; the higher the number, the more air you’re pumping into the air chamber, which will make your bed more firm. Most people have a Sleep Number in the 30-60 range. And fun fact: Sleep Number’s CEO, has a Sleep Number of 40.

If you head to a Sleep Number store, you can test out the mattress yourself until you find “your” number. You can always adjust the number once you’re home. To find it yourself, begin by lying on your mattress in your preferred sleeping position (which is typically the position you wake up in). Then, press any button on the remote to activate it. It will shut itself off automatically after a few minutes. If you’re in a dual-chamber bed (remember: full size or larger) press the “L” or “R” button on the remote control to activate the pump from the left or right side of the bed. Use the up and down arrow buttons to increase or decrease air pressure on each side of the bed.

So…How Likely Is It My Sleep Number Will Deflate?

This brings us to the question you might have been wondering about for awhile: Will my Sleep Number bed deflate like other air mattresses often do?

The answer, if you ask Sleep Number, is no, usually not. There’s an entire page on Sleep Number’s website devoted to air loss issues, along with two helpful videos if anything were to go aray. However, the company says air loss is “very rare,” and there are luckily a lot of ways to troubleshoot the issue before needing to bring a technician in.

Still, it’s hard to ignore many of the reviews that spoke about a hose issue fitting into the chamber or a remote saying ER (error). It’s impossible to know what causes each complaint, but either way, any tech issue will most likely need troubleshooting, repairs, or maybe even a replacement, depending on the severity of the problem.
