How Mattresses Are Made

This content was created by the National Sleep Foundation

Mattress construction from the inside-out

If reading about mattress construction sounds like a real, ahem, snooze, know this: The way a mattress is made determines how it feels. And how a mattress feels may be the difference between a fitful night and peaceful slumber!

The Big Picture

Two basic types of mattress make up the vast majority of the market: They’re called innerspring and memory foam. Made of steel coils, innerspring is, by far, the most common type. Memory foam, on the other hand, is made from polyurethane or latex foam, and is very dense foam. Memory foam is usually more expensive than innerspring.

Inside an Innerspring Mattress

Coils determine how much support (suspension versus springiness) the mattress will give. Manufacturers may use different types of coil shapes and structures, as well as different amounts of spacing and patterns to affect comfort. The next layer, top padding, isusually made from polyurethane foam. The outer layer (or ticking) is the material bound to the top padding with stitching. The way that ticking and top padding are attached influences the mattress’s overall feel. Large, wide patterns will create a cushioned feel, which smaller patterns feel tighter and firmer. Generally, the more coils an innerspring mattress contains, the more comfortable it’s bound to be—but if the number of coils is over 390, then you’re not likely to notice the difference, so don’t bother paying extra.

Inside a Memory Foam Mattress

Especially attractive to people with chronic pain conditions, memory foam mattresses consist of, essentially, very dense foam. When you lie on a foam mattress, your body heat softens the material, allowing it to “mold” to your body. One big advantage: In bigger beds, a memory foam mattress won’t shift as much as an innerspring when one partner turns or moves. So if you’re often disturbed by your partner’s tossing and turning in the middle of the night, it might be time to invest in a memory foam mattress. But one con: Because these mattresses mold to your body, they can absorb a lot of heat and make you feel hotter while you sleep. Some people also complain that they have a chemical smell.

Sleep Number Bed Review (2020) – The Complete Guide

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 coverevery detailabout 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 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?

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 will 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:

The Classic series models arethe 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 instandard 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 someunique 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:

  • 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.)
  • Timer feature changes the raised part of the bed at a certain time in an effort to shift the sleeper into a different position at a designated time.
FlexFit 3:

Includes all of the features in FlexFit 2and the following features:

  • Turn on a soft light under the bed and control the nightstand lamps with one button
  • Massage soothes tired muscles and leaves the sleeper feeling rejuvenated

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 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.

***From Sleep Number:The FlexFit™ adjustable base is not covered under our 100-Night In-Home Trial and is non-returnable.Delivery and set up outside the standard Comfort Service. When purchasing online, one must select the Home Delivery option. Standard UPS shipping is not available for adjustable bases.***

SleepIQ Technology

SleepIQ Technology senses how a person sleeps and provides data that lets him or her make modifications to optimize his or her night’s sleep. It can let someone know what that person’s best sleep hours are and help him or her find the best Sleep Number setting.

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

  • Fitbit
  • MapMyFitness
  • Apple Health
  • Microsoft Health
  • Nest

*This list was provided by a Customer Service representative and is subject to change.

Only some models come with SleepIQ Technology included in the mattress, but the technology is available to be added to any Sleep Number bed.

How To Choose The Right Model

There are several resources and ways to decide which mattress (and/or base) is the best match.

Online:

Sleep Number’s website offers details, photos, FAQ’s, and images of each Sleep Number bed.They let potential customers compare models across series and have a Live Chat feature that should answer virtually any question. People can also get a quote or make a purchase online and through the Live Chat feature.

In-Store:

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 anyone who walks in find their Sleep Number and guide them towards the right model. They have a variety of beds out and available for testing if a person wants to feel one before he or she makes a purchase.

Beds come with a 30 or 100 night trial period plus a 25-year limited warranty.

Who Might Want A Sleep Number?

  • People who like air beds-First and foremost, the core of the Sleep Number bed is theadjustable 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.

  • 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.
  • 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.

  • 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 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– 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 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.

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

  • 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.

100 Night In-Home Trial Period

Sleep Number allows customers to take their 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 toread Sleep Number’s policy in full on their website

  • Sleep Number® beds and DualTemp™ layers are covered by an In-Home Trial Period that begins the day your new Sleep Number bed or layer arrives.

Curious to know more about Sleep Number beds and how they work? Take a look at our full breakdown of the beds and available models below. Or check out our full Sleep Number review.

Components

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 your Sleep Number setting.

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 remotethat 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.

Comfort Foam

Except for the C-2 Classic Series model, all Sleep Number mattresses come withat least one layer of comfort foamthat rests above the air chamber(s) and below the mattress top.

Sleep Number offers a variety ofdifferent comfort foam layers in a range of densities and thicknessesfrom 1.5” inches thick (Value Beds) to 4” inches thick (360® Smart Beds).

The higher the series, the more cushion/thicker layer each mattress will have. For example, the C-2 model will be the firmest 360® Smart Beds, while the I-10 model will have the most cushion (4” layer).

Some mattresses offerPlushFit foam or enhanced foamwhile others will have Memory Foam layers.

Mattress Tops

Just like comfort layers, Sleep Number beds come ina 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 zipperin which you can reach all of the layers and the air chamber(s) at once.

Available Models

360® Smart Beds

  • Classic Series: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.

You can read full reviews of the C-2, C-4 and CSE models here (may not currently be available).

  • Performance Series:These models are the P-5, P-SE (Special Edition) and the P-6 models. The Performance series offer pillowtop style mattresses and have thicker comfort layers to be more pressure relieving.

You can read full reviews of the P-5, and P-6 models here.

  • Innovation Series:Innovation series the top of the line set of mattresses with duvet-style pillow tops and In-Balance temperature balancing material built into the covers.

You can read full reviews of the I-7, I-8, I-10, and I-LE models here.

Value Beds

  • S1 and S3 models are considered Sleep Number’s “Value Beds”.This means that they don’t have sensors built in to automatically adjust to help you sleep. Instead, they’re more like the older models that let you manually control the comfort and firmness (and your Sleep Number setting) with a remote.
  • They have 1.5″ of comfort layers and 5-zoned areas of support.

Sleep IQ Technology

Sleep IQ Technology is a proprietary program that works with Sleep Number beds to track your sleep each night and help you find your optimal Sleep Number setting.

According to Sleep Number, it can tell you your best sleep hours and connect to your health and wellness apps to provide even more insight into your quality of sleep.

It requires a specific type of pump for your bed. You can add on the Sleep IQ Technology by switching out this pump if you decide you want it after your mattress purchase.

Sleep IQ Technology isincluded in the Memory Foam and Innovation Series models.You can add it on to any Classic or Performance Series model for an additional $199.

Modular & Adjustable Bases

Not included in the price of your Sleep Number mattress butavailable for purchaseare modular bases and a series of adjustable bases.

Whileyou don’t have to use Sleep Number’s modular basefor your mattress, it does replace a traditional box spring and is available for $299 for a Queen.

There are three levels of FlexFit adjustable bases that will essentially enhance your Sleep Number experience.

  • FlexFit 1:Raises the head of your bed

Testing Sleep Number’s It Bed Claims

CR finds the new adjustable air bed falls short of its brandmates

Sleep Number’s adjustable air beds have been a hit with Consumer Reports’ readers and have done well in our tests for the past few years. In our surveys, readers tell us that adjustable air beds help them sleep, especially if they have aches and pains. And in our mattress tests, Sleep Number beds have earned consistently high marks for support and durability. Then along comes the It Bed by Sleep Number, which the company claims is "smarter than the average bed." We don’t test for that, but we can tell you whether it will help you sleep.

The It Bed by Sleep Number, $1,100, is a bit of a departure for the company in the way it’s sold and delivered. Most shoppers buy a Sleep Number bed in one of the company’s 450 stores and have it delivered and set up in their home by the company. The It Bed is a direct-to-consumer play like the trendy beds-in-a-box from Casper and Tuft & Needle. You buy it online and set it up yourself. And that’s what we did.

Our Mattress Tests

In our labs, we put the It Bed through our tests for support, durability, and motion transfer with test subjects of different sizes and in various sleeping positions. The It Bed by Sleep Number offered only mediocre support for petite, average, and large/tall sleepers who sleep on their side or back and was worse than that for large/tall back sleepers. It’s also less forgiving when one partner changes positions, meaning the other will probably be shaken or jostled.

By contrast, in our tests its two brandmates, the Sleep Number i8 Bed, $3,000, and the Sleep Number c2 Bed, $800, provide very good support for all side sleepers, and even better for some who sleep on their back. And when one partner tosses and turns, the other is less likely to be bothered.

The part that’s smart on the It Bed is the WiFi-enabled pump and the SleepIQ app, which lets you adjust the air bladders from your smartphone and track your sleeping habits. The other two beds we tested are controlled by a remote; if you already have one of them, you can add the new pump for an extra $300. The SleepIQ app is free.

Finding Your Sleep Number

Whether you buy your bed in the store or online, Sleep Number encourages you to find your sleep number by inflating the bed to 100, then slowly letting air out of the bladders until you feel comfortable in your normal sleeping position. At home you’re on your own, but in the store you have help from an apparatus that measures your pressure points as you lie on the mattress. The majority of people who own the conventional Sleep Number beds prefer settings from 35 to 50, according to a company spokesperson. By contrast, owners of the It Bed by Sleep Number prefer a setting of 80.

CR captures both preferences. In our adjustable air mattress tests we use two settings: 35 and 85. We average the two, and our experts have found that there’s little difference in support and firmness between Sleep Number’s lower and higher levels of inflation. The new It Bed scores a 3 in firmness on a scale of 1 to 10, with 10 being the firmest.

Later this year, Sleep Number is coming out with a new line of adjustable air mattresses called the Sleep Number 360 Smart Bed. They’ll have some intriguing features, including one that adjusts the bed automatically by adding or removing air as you change positions, a foot warmer that kicks in shortly before your normal bedtime, and a so-called snore detector that raises your head via the adjustable base to alleviate mild snoring. It comes with SleepIQ and can sync with your fitness tracker and other apps including the one for the Nest thermostat to adjust the temperature based on its reading of your body temperature.

Once the Sleep Number 360 mattresses hit the market, we’ll evaluate whether to buy and test one. We also plan to test adjustable air beds from other brands in addition to more innerspring and foam mattresses.

Sleep Number Product Features

Product Specs – 3.5 / 5

Sleep Number mattresses are made of a combination of contouring foam layers and a layer of air pockets that can be inflated and deflated to reach the perfect level of firmness, which is expressed in the famous "sleep number." In beds that accommodate two people, the level of firmness of each side of the mattress can be adjusted independently, allowing each sleeper to make their side of the bed as firm or soft as they find comfortable. The company fails to list the exact materials used in the manufacturing of their mattresses.

Sleep Number offers six mattress models. The core line is composed of the c2 and c4 beds, which are the most affordable ones. The c2 model lacks a comfort layer, while the c4 features SleepIQ technology, which tracks sleep habits.The 360 Smart Bed line, on the other hand, has the p5, p6, i7, i8, and i10 models. The difference between these models is the thickness of the comfort layer. Additionally, the "i" models have a "temperature balancing sleep surface," that helps owners sleep cooler at night. All 360 Smart Beds have SleepIQ technology and Responsive Air technology, which respond to the sleeper’s movements to adjust firmness automatically.

According to Sleep Number, its beds are not compatible with traditional box spring foundations, so their own base must be purchased. Customers can choose between the integrated base and a range of adjustable bases that control the position of the head and feet and may also feature foot warming and under-bed lighting.
