We receive free products to review and participate in affiliate programs. See our disclosure page for more information.

Sleep Number may be best known for its adjustable air beds, which are built in a way that either automatically adjusts to meet the sleeper’s needs (360®  Smart Beds) or allows the sleeper to change the firmness and support of the bed with the touch of a button (Value Beds).

The Sleep Number 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 is there to know about Sleep Number beds and can a person find the best match among all the options available? In this Sleep Number Bed review, we cover every detail about Sleep Number beds, plus factors to consider before making a purchasing decision, including who manufactures the beds, what special sizes options are available, features, and more. Don’t forget that in-home trial period and warranty, too.

Who Makes Sleep Number Beds?

Sleep Number beds are made by Select Comfort Corporation (Select Comfort), which is a public company. They design, manufacture, market, and distribute beds, proprietary beds, and other sleep-related accessory products and are headquartered in Minneapolis, Minnesota.

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.

What The Numbers Mean

sleep number bed app with sleep iq technologySleep Number is all about beds, but in case it wasn’t obvious, they’re also all about numbers.

A person’s Sleep Number number (also called a Sleep Number setting) corresponds to the individual’s ideal firmness and support. Numbers range from 0 to 100 and the higher the number, the more air/firmer the feel of the Sleep Number bed will be.

Likewise, the lower the Sleep Number, the less air will be in the air chamber and the softer the bed will be.

Sleep Numbers are super personal and can change. If an individual determines what he or she thinks his or her setting is in the store and go home and don’t like it, there is no reason the person can’t adjust the number till he or she finds a good fit.

The Most Popular Sleep Number?

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.

Sleep Number also told us that, in terms of models, some common options are the C2 for the price point, P5 for the best value, and I8 for best comfort and the added cooling.

How Do I Find My Sleep Number?sleep number bed remote control

A 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 the individual.

Those who want to know their number before purchasing a mattress, they can visit their closest Sleep Number store and have a sales representative walk them through the process. At the store, the person will rest on a Sleep Number bed and they will inflate/deflate the floor model till they find a comfortable spot.

After purchasing a Sleep Number bed and having it delivered and (potentially) set up, individuals can use the remote it comes with to start determining their Sleep Number. Instructions are provided Sleep Number’s website; some of the steps include asking the sleeper to lie in their “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.

Bed Construction

Enough about numbers, let’s talk about what’s actually in a Sleep Number bed.

Air Chambers

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 the individual’s Sleep Number setting. Sleep Number calls this feature “DualAir technology.”

The higher the number (it goes up to 100) the firmer the mattress will be. When there are two air chambers, each person can adjust the amount of air in their air chamber based on their personal preference.

The S1 and S3 value beds will come with a single remote and the 360 smart beds (the rest of the options) will just adjust to the person’s needs automatically and do not come with remotes.

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.

Comfort Foam

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 2” inches thick to 7” inches thick.

The higher the series, the more cushion/thicker layer each mattress will have. For example, the C2 model will be the firmest (with a 2″ foam layer) while the I-10 model wilsleep number models - comfort layersl have the most cushion (7” layer).

360®  Smart Beds – Responsive Air Technology

These beds have technology built into the mattress construction that senses the sleeper’s every moment, from heart rate and breathing and then automatically changes the firmness, comfort, and support using the brand’s “responsive air technology” feature.

Sleep Number Series/Model Breakdown

Sleep Number offers two types of beds:

  • 360®  Smart Beds
  • Value Beds

The 360®  Smart Beds are organized into three categories: Classic, Performance, and Innovation.

Each series essentially builds off the other. The Classic Series beds, the C2, and C4 offer the most standard options while the Innovation Series has the largest, thickest layers and most added features.

Classic Series:

Sleep Number Mattress Classic Series c2 and c4The 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 the top of the mattress.

Sizing

While sizes vary depending on the model, most Sleep Number beds come in standard sizes that will fit most traditional frames and box springs:

Dimension
Twin38” x 75"
Twin Long38” x 80”
Full54” x 75”
Double54” x 75” (same as Full)
Queen60” x 80”
King76” x 80”
California King72” x 84”

Sleep Number beds also come in some unique and specialized sizes: Split King and FlexTop King (and Cal King)

DimensionDescription
Split King76” x 80”split all the way to the foot of the bed
FlexTop King76” x 80”split only at the head of the bed
FlexTop California King72” 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, the sleeper can raise/lower just the head and feet of his or her side of the bed. If the person’s partner is snoring, he or she could raise the head of just their side with a FlexTop.

Modular & Adjustable Bases

Since Sleep Number is all about individualized comfort, it is not surprising that they also make different types of bases for the mattress.

Sleep Number makes one modular base and three different adjustable bases for their mattresses: FlexFit 1, FlexFit 2 and FlexFit 3.

Note: A Sleep Number’s modular or adjustable base is not the only base that works with a Sleep Number mattress. All one needs to have is a flat and sturdy surface for the mattress or the individual may potentially void his or her warranty.

Modular & Adjustable Base Descriptions

Modular Base:

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 the mattress. It is also easy to get through narrow spaces and set up in smaller rooms so it could be ideal for apartment living.

FlexFit 1:

Raises the head of the bed; one remote will control the elevation of the bed and adjust the Sleep Number in the same device.

FlexFit 2:

The most popular FlexFit Base. It raises the head of the bed like the FlexFit 1 and offers the following additional features:sleep number flexfit base features

  • A “Zero Gravity” option that raises the head and foot in a way that leaves the sleeper feeling weightless
  • Partner Snore™ technology allows one partner to raise the other partner’s head (Available with Split King, Split California King and FlexTop® King beds.)

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 customers will be able to see the legs underneath like a regular frame. If a person chooses the Traditional option, we recommend purchasing our Smart™ Skirt Bed Skirt.

When purchasing online, one must select the Home Delivery option. Standard UPS shipping is not available for adjustable bases.***

It also connects to a number of health and wellness apps*, including:

Who Might Want A Sleep Number?

  • People who like air beds- First and foremost, the core of the Sleep Number bed is the adjustable air mattress. Those who have had a positive experience with air beds, they will probably like what Sleep Number has to offer – especially with all of its adjustable features.

sleep number bed firmness adjustment

  • Couples who sleep differently– Couples who have different support level preferences may like Sleep Number beds because most beds can be made with dual air chambers that allow each person to decide how firm their side of the bed will be. Some models – like the I-10 – even have comfort layers that can be adjusted on each side.sleep number is good for people with injuries
  • People with physical injuries or medical conditions– Whether it’s a bad back, occasional heartburn or recovery from an accident, Sleep Number’s adjustable mattress, and FlexFit bases allow people to get comfortable easily and then re-adjust when they’re back to normal.

mattress firmness flexibility

  • People who want options and flexibility– Individualized comfort is the name of Sleep Number’s game, so it’s no surprise that people who want to be able to change things up on a nightly basis will like these models. Sleepers can adjust the firmness, pick a model whose layers fit their needs – some can even help to sleep cool – and they can add a FlexFit base for even more sleeping options.

Who Might Not Want A Sleep Number?

people who like memory foam might not like sleep number bed

  • People who love memory foam– Depending on what is available, there are one – possibly two – Sleep Number models that offer a comfort layer made with memory foam. Those who love the feel of classic memory foam will be limited on Sleep Number beds, which are – at their core – adjustable air beds.

couples who like to sleep close together might not like sleep number bed

  • Couples who like to sleep close together– One of the biggest complaints from couples is that a sagging/division is created in between the dual air chambers on the bed. Couples who like to sleep close or cuddle in the center of the bed feel as those they are sinking into the middle of the bed.

people who don't want to deal with technology might not like sleep number bed

  • People who do not want to deal with technology– People who prefer a simpler tech-free bed, Sleep Number may not be the best fit. Sleep Number’s 360 Smart Beds will adjust to the sleeper’s needs automatically and the Value Beds will need a remote for adjustments. The remote will signal a pump to inflate/deflate air into the air chamber(s) in the mattress to adjust firmness. Sleepers who want insight into their sleep habits will need to utilize the SleepIQ technology, which can be connected to other apps on a person’s smartphone.
  • People on a tight budget– Of the 10 models currently available at Sleep Number, only two are available for under $1,000 at a Queen size (at full price). This is the C-2 360 Smart Bed and the S-1 Value Bed. Those wanting additional comfort layers, cooling features and maybe a specialized FlexFit base will need to be ready to spend upwards of $5,000 for a Queen bed with added comfort features.

Ratings and Reviews – Common Praise

sleep number common praise

  • Couples love being able to personalize the firmness of their side of the bed. The dual air chambers available on most models (and depending on size) means that someone who prefers a firmer bed doesn’t have to compromise with a partner who likes more cushion.  If one person likes to sleep on their side and another doesn’t, they have a great solution here.
  • People with back problems or medical issues that require them to sit up at different points love the flexibility of Sleep Number beds. They can adjust the firmness of their bed for a couple of nights if needed and can raise/lower the head of their bed with a FlexFit Adjustable Base depending on their current needs.
  • There was heavy praise for the longevity and durability of the Sleep Number bed. People came back to Sleep Number’s site to say they’ve had their bed for 10+ years and they are still comfortable. Of course, not everyone was able to stay comfortable in their bed for a decade without experiencing issues, but people tended to have their Sleep Number bed for a long time.

Common Complaints

common complaints for sleep number beds

  • As with all products, some people just did not find their Sleep Number bed comfortable. These types of reviews are common and typically all come down to personal preference. Those who are unsure about investing in a Sleep Number bed, go to a store and try one in person to see what they think.
  • People reported being frustrated with the limitations attached to Sleep Number’s 100 Night Trial Policy and their 25 Year Limited Warranty. People complained that they purchased an adjustable base without knowing that it wasn’t a part of the trial and couldn’t be returned. People were also upset that they had to pay a portion of the cost to fix their Sleep Number bed after the first two years of their 25-year limited warranty. It would be worth reading both the policy and warranty in full before making a purchase.
  • One popular complaint was a sagging or slight valley created in the mattress between the two air chambers. This seemed to be a bigger complaint about models that had thicker comfort foam layers. Couples expressed disappointment in not being able to cuddle in the middle of their bed without feeling like they were falling/sliding into the center.
