Sleep Number may be best known for its adjustable air beds, which are built in a way that allows you to change the firmness and support of the bed with the touch of a button. The beds tend to be popular with couples because they can be made with dual air chambers, so each person can adjust to their preferred setting without compromising.
What else do you need to know about Sleep Number beds and how will you pick the best one for you? Don’t worry, we’ve got you covered with everything you need to know about Sleep Number, including who makes the beds, what special sizes, features, and options they offer. Don’t forget that in-home trial period and warranty, too.
Select Comfort was founded by Robert Walker and JoAnn Walker in 1987. Today, the company has around 3,700+ employees and was listed as the 87th best Small Company in America by Forbes.
Select Comfort has two manufacturing plants – one in Irmo, South Carolina and the other in Salt Lake City, Utah – which distribute products in the United States and Canada.
Sleep Number is all about beds, but in case it wasn’t obvious, they’re also all about numbers.
Your Sleep Number number (also called your Sleep Number setting) corresponds to your ideal firmness and support. Numbers range from 0 to 100 and the higher your number, the more air/firmer your Sleep Number bed will be.
Likewise, the lower your Sleep Number, the less air will be in your air chamber and the softer your bed will be.
Sleep Numbers are super personal and can change. If you determine what you think your setting is in the store and go home and don’t like it, there is no reason you can’t adjust your number till you find what suits you best.
The most popular Sleep Number is in the 35-40 range. When I asked a representative why this is range is so popular, I was told: Sleep Number is really based on personal preference and what is most comfortable for each person, the 35-45 range gives great support and pressure relief for most.
Your Sleep Number can be determined either before or after purchasing a Sleep Number bed. It will really all come down to what feels “right” to you.
If you want to know your number before purchasing a mattress, you can visit your closest Sleep Number store and have a sales representative walk you through the process. At the store, you will rest on a Sleep Number bed and they will inflate/deflate the floor model till you find a comfortable spot.
After you purchase your Sleep Number bed and it’s delivered and set up, you can use the remote it comes with to start finding your Sleep Number. Instructions are provided Sleep Number’s website; some of the steps include asking you to lie in your “waking up” sleep position and letting the mattress to go from soft to firm and back from firm to soft. This way can identify which firmness level is best for you.

Enough about numbers, let’s talk about what’s actually in a Sleep Number bed.
All Sleep Number mattresses come with one or two air chambers. These air chamber(s) use a pump to bring in air that will inflate or deflate the chamber based on your Sleep Number setting. Sleep Number calls this feature “DualAir technology.”
The higher the number (it goes up to 100) the firmer your mattress will be. When you have two air chambers, each person can adjust the amount of air in their air chamber based on their personal preference.
Almost every model comes with one remote that allows you to program your Sleep Number. The I-10 model is the only one that comes with two remotes and is only available with dual air chambers.
Air chambers make up the base of all Sleep Number models except for the Innovation Series beds, that feature 1” or 2” foam base pads. These pads are used to add height and support, according to Sleep Number Customer Service representatives.
Except for the C-2 Classic Series model, all Sleep Number mattresses come with at least one layer of comfort foam that rests above the air chamber(s) and below the mattress top.
Sleep Number offers a variety of different comfort foam layers in a range of densities and thicknesses from 1.5” inches thick to 4” inches thick.
The higher the series, the more cushion/thicker layer each mattress will have. For example, the C-2 model will be the firmest (with no foam layer) while the I-10 model will have the most cushion (4” layer).
Some mattresses offer PlushFit foam or enhanced foam while others will have Memory Foam layers.
Just like comfort layers, Sleep Number beds come in a range of mattress tops. Pillowtop mattresses start with the Performance Series models and expand from there.
In some cases, mattress tops can be accessed by a separate zipper on the mattress. The I-8 and I-10 models offer a Duvet-style mattress top, the most luxurious, and can be accessed by a second zipper on the mattress.
Aside from these two models, all other mattresses have one zipper in which you can reach all of the layers and the air chamber(s) at once.
Sleep Number offers several models broken organized into four categories: Classic, Performance, Memory Foam and Innovation.
Each series essentially builds off the other. The Classic Series beds, the C-2, C-4 and CSE, offer the most standard options while the Innovation Series have the largest, thickest layers and most added features.
The Classic series models are the most basic mattresses. They will have the firmest feel to them because there is the least amount of layers between the air chamber and your mattress top.

While sizes vary depending on the model, most Sleep Number beds come in standard sizes that will fit most traditional frames and box springs:
|Twin||38” x 75"|
|Twin Long||38” x 80”|
|Full||54” x 75”|
|Double||54” x 75” (same as Full)|
|Queen||60” x 80”|
|King||76” x 80”|
|California King||72” x 84”|
Sleep Number beds also come in some unique and specialized sizes: Split King and FlexTop King (and Cal King)
|Split King||76” x 80”||split all the way to the foot of the bed|
|FlexTop King||76” x 80”||split only at the head of the bed|
|FlexTop California King||72” x 84”||split only at the head of the bed|
The Split and FlexTop mattresses are best paired with a FlexFit Adjustable Base. For example, with a Split King you can raise/lower just the head and feet of your side of the bed. If your partner is snoring, you could raise the head of just their side with a FlexTop.
Since Sleep Number is all about individualized comfort, it is not surprising that they also make different types of bases for your mattress.
Sleep Number makes one modular base and three different adjustable bases for their mattresses: FlexFit 1, FlexFit 2 and FlexFit 3.
Note: You do not have to use Sleep Number’s modular or adjustable bases with your Sleep Number mattress. You need to have a flat and sturdy surface for your mattress or you may potentially void your warranty.
This modular bed base is a standard base that is designed to be both sturdy and durable. Sleep Number says it will last 20 years or more and prevent sagging in your mattress. It is also easy to get through narrow spaces and set up in smaller rooms so it could be ideal for apartment living.
Raises the head of your bed; one remote will let you elevate the bed and adjust your Sleep Number in the same device.
The most popular FlexFit Base. It raises the head of your bed like the FlexFit 1 and offers the following additional features:
Includes all of the features in FlexFit 2 and the following features:
The FlexFit bases also come in two types: Silhouette and Traditional. Here is the description I got from a representative: The silhouette is an optional upholstered surround for our FlexFit adjustable bases. The Traditional option does not include the upholstered frame, and you will be able to see the legs underneath like a regular frame. If you choose the Traditional option, we recommend purchasing our Smart™ Skirt Bed Skirt.
***From Sleep Number: The FlexFit™ adjustable base is not covered under our 100-Night In-Home Trial and is non-returnable. Delivery and setup outside the standard Comfort Service. When purchasing online, you must select the Home Delivery option. Standard UPS shipping is not available for adjustable bases.***
SleepIQ Technology senses how you sleep and provides data that lets you make modifications to optimize your night’s sleep. It can let you know what your best sleep hours are and help you find your Sleep Number setting.

Sleep Number sells their beds in Sleep Number stores nationwide. Sleep Number Customer Service was unable to tell me exactly how many stores there are but estimated somewhere near 400.
Sleep Number stores can be found across the country, including Alaska and Hawaii. There are no international stores at the moment.
A sales representative at the store can help you find your Sleep Number and guide you towards the right model for you. They have a variety of beds out and available for testing if you want to feel one before you make a purchase.
Beds come with a 30 or 100 night trial period plus a 25-year limited warranty.
Sleep Number allows you take your Sleep Number mattress home to try it out for a certain period of time and under certain conditions. This is sometimes referred to as the “100- Night In-Home Trial” or the “In-Home Trial Policy.”
Here are the basic conditions of the trial period. Be sure to read Sleep Number’s policy in full on their website.
Sleep Number beds (from their Core Line of mattresses: C-2, C-4, CSE, P-5, P-6, I-7, I-8, I-10, and I-LE.) and their modular bases are covered in the 25-year limited warranty. This excludes the it™ bed.
It is highly recommended that you read the full warranty policy on the website. There are some important insights and we’ve listed a couple here:
