Sleep Number Bed Basics – 10 Simple Things You Should Know About Sleep Number Mattresses Before You Start Shopping

  1. High-tech air beds – Sleep Number mattresses are basically air mattresses. Not just any air bed, but the most advanced air mattresses on planet earth! They are not innerspring, memory foam or latex mattresses!
  2. Firmness is adjustable – Because they’re air beds, the firmness of the mattress can be increased or decreased by pumping air in or out. The technology is known as Sleep Number’s Firmness Control™ System. This is THE MAJOR UNIQUE feature of Sleep Number beds. The softness or firmness is given a number from 1 to 100; you can pick the number that suits you best; that’s your Sleep Number. My Sleep Number is 42. Yours may be 35 or 55!!
  3. There are NINE different models
    1. Classic Series – c2 and c4
    2. Performance Series – p5, p6, pSE
    3. Innovation Series – i7, i8, i10, iLE
  4. From $600 – $5000 upwards – The most basic (and cheapest) bed type is the Classic Series while the most advanced (and priciest) type is the Innovation Series
  5. Smarter than your spouse? The Classic Series is ‘dumb’ while the Performance and Innovation Series are ‘smart’. There are two aspects to this smartness: (i) Responsive Air™ technology: the firmness will sense your sleeping position and movements and automatically adjust its firmness supporting your body while you’re asleep, and (ii) SleepIQ Technology: sleep tracking technology tracks your heart rate, your movements and how well (or not) you sleep and gives you a ‘Sleep Score’.
  6. Each mattress has 3 major components
    1. The bottom air chamber
    2. The middle comfort layer
    3. The top mattress cover
  7. 8″ – 13″ thick – The air chamber and mattress cover are approximately the same across all Sleep Number Beds. It’s the thickness of the middle comfort layer that differs among the different models.
  8. Soft, Medium-Soft, Medium-Firm or Firm? The comfort layer is thinnest on the Sleep Number c2 bed. Therefore, the c2 is the firmest mattress. The comfort layer is thickest on the Sleep Number i10 bed. Therefore, the i10 is the softest mattress out of the lot. For now, you can remember the Firmest to Softest Sleep Number beds as c2, c4, pSE, p5, p6, iLE, i7, i8, and i10 in the descending order of firmness
  9. Twin, Queen, King sizes? All models (c2 – i10) are available in Queen, King, and California King sizes; but not all models are available in Twin, Twin XL, and Full sizes.
  10. Air Leaks !!! This is the MAJOR COMPLAINT against Sleep Number beds by consumers. It won’t happen immediately and it won’t happen to all mattresses… may be it’s your luck… or may be it’s just unavoidable with air mattresses

Sleep Number Reviews

This section of our Sleep Number reviews is dedicated to discussing the pros and cons of Sleep Number beds as a whole. You can find individual bed reviews at the end of this section.

Major Pros of Sleep Number Beds (Benefits)

  1. Adjustable Firmness – You can adjust the mattress firmness as and when you wish. If you buy a memory foam, inner spring or latex mattress, its firmness is fixed; if you feel you need a softer or firmer mattress, your only option is to ditch the existing mattress and buy yourself a new mattress. But with Sleep Number beds, you can fine-tune mattress firmness within a certain range.
  2. One-Touch Sleep Number Recall – You can recall your favorite firmness with the press of a single button. Might be especially useful if you have different Sleep Numbers for daytime naps, nighttime sleep, watching TV or for romantic activities 😉
  3. Partner Independence – Each partner can choose their preferred firmness independent of the other (for Queen or larger sizes as they come with two independent air chambers)
  4. Responsive Air™ Technology – When you twist and turn in your sleep, the Performance and Innovation series Sleep Number beds are able to automagically adjust firmness according to your movements. How cool is that? Built-in pressure sensors on air chambers detect your body position and make adjustments accordingly. That is as advanced as sleeping technology can get in 2018! These models are known as the Sleep Number 360® series beds.
  5. Conform to your body – Similar to a memory foam mattress, Sleep Number air beds can conform around your body
  6. USA product – Most parts are made in the USA
  7. No off gassing – especially on memory foam mattresses, there can be a slight rubber-like/chemical smell during the first couple of days, but not on Sleep Number mattresses
  8. Ready to be used – No need to let the mattresses ‘decompress’ to their original thickness once delivered to your home (unlike with memory foam mattresses). You can sleep on it as soon as it is assembled
  9. Light weight – Sleep Number air mattresses are ‘feather weight’ compared to most latex, memory foam and spring mattresses
  10. Decent motion isolation – motions/waves created by your partner’s twisting and turning won’t reach you. The bed kinda ‘absorbs’ the shocks! Not the best motion isolation in the industry, but pretty good.
  11. Good therapeutic support – great for those with back pain
  12. After sales service – Good customer service, parts readily available and easily repaired. Therefore good longevity

Major Cons of Sleep Number Beds

  1. EXPENSIVE – goes all the way up to and beyond $10,000 (for a Sleep Number 360® Split California King i10 Smart Bed on a FlexFit™ 3 adjustable base). As all online Sleep Number reviews will agree, this brand of beds are more expensive than most mattresses in the market.

  2. Malfunctions are not uncommon – there may be no rocket science behind Sleep Number technology; nevertheless, they are pretty complicated beds compared to most other adjustable beds. This ‘complexity’ makes them a little vulnerable. As a result, it’s not uncommon to see Sleep Number bed reviewers complaining about a few malfunctions. But like we mentioned earlier, their customer support is good and most of these issues can be fixed. The two major malfunctions reported are (i) air leaks and (ii) tech problems.
  3. Complicated initial use – finding that perfect Sleep Number of yours may not be as easy as it sounds. It’s not uncommon to see Sleep Number bed reviews complaining about this initial, difficult period of adapting to it
  4. Noisy – some people simply hate the sound of the air pump operating
  5. Sex-unfriendly – this is not the best mattress for sex. It’s not Sleep Number’s fault. Generally, all air mattresses get an average rating for sex-friendliness. If you have not inflated them much, you tend to sink in it. If you’ve inflated the mattress too much, then it’s too hard and bumpy. Neither one of them is a winner, from a sex point-of-view. Ideally, sex-friendly mattresses should have good bounce and good edge-support. You don’t want to roll off the edge in case you try to get adventurous. Sleep Number air mattresses aren’t generally that great on bounce and responsiveness.
  6. Online availability – Online availability is limited to non-existent 🙁 This brand of beds is not available on 3rd party e-commerce platforms like Amazon, Walmart, Overstock etc. Availability on those marketplaces would have potentially brought the Sleep Number bed prices down. Buying at your local mattress store is probably the most expensive option; but that is also the only option available to you and I 🙁

Hope this section helped you understand how Sleep Number beds differ from the rest. Like we mentioned earlier, there are several different models of Sleep Number beds. The next section is all about these different models.

What’s Unique About Sleep Number beds?

Adjustable beds

Generally, when we refer to adjustable beds, we refer to a bed whose frame/base/foundation is adjustable. i.e. you can raise the head, feet or both in various positions.

Sleep Number adjustable beds

When people refer to a Sleep Number adjustable bed, they’re referring to the adjustable firmness of the mattress, not the bed base. You have the option of either increasing or decreasing the firmness of Sleep Number mattresses, as and when you wish. You can’t do this with a typical spring, memory foam or latex mattress. This is THE UNIQUE FEATURE of Sleep Number beds.

Sure, you can put an adjustable Sleep Number mattress on an adjustable base; however, the majority of Americans use Sleep Number mattresses on non-adjustable bases like platform beds. Even then, they’re still considered ‘adjustable’. Hope we haven’t confused you too much 🙂

Sleep Number mattresses have adjustable firmness

You can adjust (increase or decrease) mattress firmness as and when you wish. Your partner can even have a different firmness setting according to his/her individual preference. And the two partners can live happily ever after enjoying their own preferred firmness.

Sleep Number beds are air mattresses

Sleep Number adjustable beds alter their firmness by increasing or decreasing air pressure inside the mattress. Yes, Sleep Number mattresses are essentially air mattresses. Each mattress has two air chambers within them. When you increase or decrease firmness, you are essentially further inflating or deflating these air chambers. An electrically operated air pump connected to the mattresses does all the pumping in/out of air to inflate/deflate.

A ‘Sleep Number’ for your favorite firmness

You can assign a number to your favorite firmness. You can simply type in that number and instantly recall that particular firmness. Let’s say you like watching TV at 50 and you like sleeping at 70. When you switch from TV watching to sleeping, simply punch in 70 and your bed will magically transform to your ‘Sleep Number’ within a few seconds.

Manufacturer of Sleep Number Beds

Select Comfort company logo
A picture is worth a thousand words. Logo belongs to Sleep Number

Select Comfort, the Minnesota-based company founded in 1987, is the creator of Sleep Number beds. However, in November, 2017, they changed their name to – no prizes for the correct guess – Sleep Number Corporation. No surprises there! Currently, they have two manufacturing plants in South Carolina and Salt Lake City (Utah).

Now that the major features of the brand have been discussed, let’s get to the meat and bones of our Sleep Number Review.

Sleep Number Bed Reviews

Here we review each of the Sleep Number beds/mattresses. Sleep Number beds come in three different product series. They are:

  1. Classic Series
  2. Performance Series
  3. Innovation Series

Sleep Number Classic Series Bed Reviews

This is the ‘entry-level’ series of Sleep Number beds. It is available as three models: the C2, and the C4.

Sleep Number C-2 Review

The Sleep Number C2 is a plush-type 8 inch air bed. One of it’s major features is its dual air adjustability. In other words, you can have two different comfort settings for the two partners. It is also Sleep IQ-ready; so if you want to make use of the one-of-a-kind sleep IQ technology (costs ~an extra $150), remember that the C-2 is compatible with it. Note that the C2 is also FlexFit adjustable bed-friendly.

If you’re really interested on the C2, we have you covered! Check out our detailed Sleep Number C2 Review for up-to-date information.

Sleep Number C4 Review

The Sleep Number C4 is a 10 inch air bed with zoned cushioning comfort. This is a high-end feature rarely found on mattresses. 1 1/2 of the 10 inches is a soothing foam comfort layer. Similar to the C2, the C4 also has dual air adjustability. Like the C2, the Sleep Number C4 is compatible with the Sleep IQ-technology and adjustable bases.
