​​Sleep Number Bed Reviews

Sleep Number Beds Reviews

​​Sleep Number adjustable beds are a must have for some of ​us; but not for others

​Sleep Number Basics

​1. Sleep Number beds are Air Beds

Sleep Number Bed Reviews

​Sleep Number beds are NOT:

  • Memory Foam Mattresses
  • Latex Mattresses
  • Innerspring Mattresses
  • Water Beds

Instead, they’re simply air beds; not just any air bed, they’re the most advanced type of air beds on planet earth… keep reading to find out ​what’s so special about them….


​2. Adjustable Firmness

Adjustable Firmness of each bed

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. ​Four Series, ​11​ ​Models

9 mattress models

  1. Value/Legacy Series​ – S1 and S3
  2. Classic Series – c2 and c4
  3. Performance Series – p5, p6, pSE
  4. Innovation Series – i7, i8, i10, iLE

​4. ​Smarter than your spouse?

Sleep Number 360 Smart Review

There are two aspects to this smartness:

​While the Legacy/​Value-bed Series is ‘dumb’, ​Classic, Performance and Innovation Series are ‘smart’ ​(​back in the day, even the classic series was ‘dumb’; but over the years, has evolved to become ‘smart’, like you and I :)).

  1. Responsive Air™ technology: the firmness will sense your sleeping position and movements and automatically adjust its firmness supporting your body while you’re asleep 
  2. SleepIQ™ Technology: sleep tracking technology tracks your heart rate, your movements and how well (or not) you sleep and gives you a ‘Sleep Score’.

This split-king type bed is also smart, but in a different way to Sleep Number.

​5. ​Made of 3 major ​’layers’

3 layer mattress

​Each type of mattress ​is made of 3 major components

  1. The bottom air chamber
  2. The middle comfort layer
  3. The top mattress cover

​6. Choose between ​8″​ – 13″ thickness ​

Sleep Number Bed Thickness

​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.

​7. ​​Choose between Soft, Medium-Soft, Medium-Firm or Firm

Sleep Number Bed Firmness

The comfort layer is thinnest on the Sleep Number c2 bed. ​That’s why the c2 is the firmest mattress among its siblings. The comfort layer is thickest on the Sleep Number i10 bed; ​that’s why 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, i8, i7, and i10 in the descending order of firmness

​8. ​From ​$600 – $5000 upwards

Sleep Number Mattress Prices

​The most basic (and cheapest) bed type is the Classic Series while the most advanced (and priciest) type is the Innovation Series

​9. ​​Comes in Twin, Queen, King sizes

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 !!!

air leaks on sleep number beds

​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.

Unfortunately, ​out of 100s of Sleep Number bed reviews we analyzed, ​as much as 10% of customers complain of air leaks of some nature!

​Sleep Number ​Pros and Cons

​​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 Sleep Number bed reviews at the end of this section.

4 Major CONS (​complaints) of Sleep Number Beds

1. ​Air Leaks

Sleep Number Air Leaks

​​​Based on online Sleep Number Bed Reviews left by ​Sleep Number consumers, more than 10% of the users complain of air leaks. The most popular causes of air leaks in Sleep Number mattresses are faulty air pumps, malfunctioning controllers, leaks on the air bladders, leaky hoses or loose connections. ​

​The whole concept of adjustable firmness depends on ​control of air pressure. If air leaks out, that whole concept becomes an utter disaster.

2. Trench ​Effect​

Trench in mattress

Queen and King-size Sleep Number beds ​have two independent chambers ​allowing the two partners to have two different firmness levels on their respective sides. 

The downside of this is that a ‘trench’ can form between these two air chambers which is NOT ​helpful ​towards cuddling, spooning, or other intimate activities ;(

​3. ​​Hammock Effect

Hammock effect sleep number sagging

​This happens if you try to make the bed very soft. For example, a Sleep Number of 40 would be very deflated and therefore, ‘soft’. When you ​climb on to such a bed, you automatically roll to the middle and ‘sink’ while ​the air shifts to the periphery of the mattress. This gives rise to a hammock or sagging effect.

​You can avoid this to a certain degree by purchasing a Sleep Number bed on the soft side of the spectrum like an i7, i8 or i10. This hammock effect is more likely to happen if you buy a firm mattress like the c2 or c4 and then deflate it to get a soft setting.

​4. ​Expensive​

Sleep Number Adjustable Bed Pricing

​Sleep Number bed prices ​can go above 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 ​is more expensive than most mattresses in the market.

5 Major Pros (Benefits) of Sleep Number Beds

adjust firmness softness

1. Adjustable ​Firmness

​With a memory foam, inner spring or latex mattress, its firmness stays fixed. Such a mattress does NOT let you increase or decrease the firmness of the bed; your only option is to ditch your current mattress and buy yourself a new mattress.

But with Sleep Number air beds, you can fine-tune the firmness of your mattress ​​by inflating it or deflating it, within a certain range. ​

Responsive Air Technology of Sleepnumber Beds

2. Responsive Air™ Technology

​When you twist and turn in your sleep, the Classic, Performance and Innovation series Sleep Number beds ​can automagically adjust firmness according to your movements. ​Built-in pressure sensors on air chambers detect your body ​movements and make adjustments accordingly. That is as advanced as sleeping technology can get in 201​9! These models are known as the Sleep Number 360® series ‘smart’ beds.

split king adjustable beds

​​3. ​Dual Air™ Technology

Each partner can choose ​his or her preferred firmness independent of the other (for Queen or larger sizes​ that come with two independent air chambers). So for example, the wife can have a firmer setting and the husband can have a softer setting on the same mattress!!

In other words, two people ​sleeping on the same bed ​can have very different firmness settings. The only way to do this with a conventional mattress is if you owned a split-king bed like this one.

Sleep Number Remote

4. One-Touch Sleep Number Recall

​You can ​give your favorite firmness a ‘Sleep Number’ and recall it instantly with ​the touch ​of a ​button. This is ​especially useful if you ​want to have ​different ​firmness levels for daytime naps, nighttime sleep, watching TV or for romantic activities 😉

Sleep Tracking SleepIQ Technology

5. ​​SleepIQ™ Technology 

​A state of the art sleep tracking technology that tracks your heart rate, ​hours of sleep you get, how much you move, how much you sleep walk (just kidding) etc. and ​computes a ‘Sleep Score’ accordingly. This feature, seen on Sleep Number 360 smart beds, is mediated via built in biometric sensors.

​We hope you found our Sleep Number Pros and Cons useful and it helped you ​decide if Sleep Number is right for you or not. If you decided in favor of purchasing a Sleep Number bed, your next step should be to narrow down on the exact model of Sleep Number bed that would suit you the best. We hope the following section on individual Sleep Number bed reviews will help you doing just that!

​Sleep Number Beds Overall Review and Comparison

​Before we get into details on the ​four types of Sleep Number series, let us give you an overview of the ​11 different mattresses. The ​11 mattresses have ​different thicknesses, ​different firmness levels and different ​comfort layer thicknesses. We have ​illustrated all of that data for you on ​the following two graphics.

The first graphic below shows the different thicknesses of the comfort layer and the entire mattress of the different types of Sleep Number beds ​starting ​from the thinnest C2 to the thickest i10.

Comparison ​of Comfort Layer Thickness

Comparison of Firmness Levels of Different Sleep Number Beds

​The second graphic below shows the different firmness levels of the different beds ranging from the soft i7 to firm c2. Notice that these beds have a range of firmness unlike a regular spring, foam or latex mattress. As an example, depending on how much you inflate or deflate the p​6, its firmness can be decreased to ​a minimum ​4 or increased to a maximum of ​6. You can’t make it a 3 however much you deflate it or you can’t make it a 7 however much you inflate it! ​

Sleep Number Mattress Firmness Scale

​Now that we have given you a broad idea about the differences on each mattress, we will go on to review each of the ​4 different ​categories of mattresses, namely, the Legacy Series, the Classic Series, the Performance Series and the Innovation Series.

Sleep Number ​S1 and S3 Value Bed Series Review

The ​Value-bed Series also known as the Legacy series consists of the s1 and s3 beds. This is the only ‘dumb’ series of beds. This doesn’t get categorized under the Sleep Number 360 ​Smart Beds. Nevertheless, s1 and s3 are kind of semi-smart because they still have Dual Air and SleepIQ technologies. The only smart technology that it lacks is the Responsive Air technology.

​1. ​Sleep Number s1 Bed Review

Sleep Number s1 Review

​​Major Features of the ​s1 bed

  • This is the most basic, entry-level Sleep Number bed
  • Thickness: it is ​10″ thick; that’s 2″ ​thicker than the 8″ c2 mattress
  • Firmness: it is one of the firmest ​with a 6-7 reading on the firmness scale​. This is the same firmness as the Sleep Number c2
  • Comfort layer: it is 1.5″ ​thick ​and is the thinnest out of all Sleep Number beds. ​The ​5-zoned comfort layer is designed to ​contour around the body and to ​reduce ​stress on pressure points on the 5 zones (i) head, (ii) neck, (iii) lumbar area, (iv) hips, and (v) feet
  • Price: ​​$999 for a queen size bed
  • ​Smart technologies: The s1 is a semi-smart bed – ​it has the SleepIQ technology that measures your heart rate, how long you slept etc. But it doesn’t have the ​Responsive ​Air ​technology that is responsible for automatically changing firmness
  • ​Dual Air technology: yes, the two partners can have their own independent firmnesses/Sleep Numbers on queen and king sized models. However, you get only 1 remote controller for ​the whole bed.

  • ​Dual Air and ​SleepIQ technologies: ​all that is similar to the s1

​​1. Conforms to your body

​Similar to a memory foam mattress, Sleep Number air beds can conform around your body if you don’t set it to too firm a setting

2. Light weight

Sleep Number ​AIR mattresses are ‘feather weight’ compared to most latex, memory foam and spring mattresses

3. 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

​4. 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

5. Great after-sales service

Good customer service, parts readily available and easily repaired. ​However, it is not uncommon to see people complaining about long waiting times with Sleep Number ​support.

​6. 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.

7. USA Product

Most parts are made in the USA

8. Good therapeutic support

Great for those with back pain

Frequently Asked Questions

Is Sleep Number Really That Good?

If you sleep alone and have a consistent firmness preference, Sleep Number is an overpriced option. However for couples with vastly different tastes in mattress firmness, those adjustable air-filled chambers could be worth it!

What Is The Lifespan Of A Sleep Number Bed?

The average mattress lifespan is 6-8 years, but the expected lifespan of a Performance series airbed from Sleep Number is about seven to eight years.

Can A Sleep Number Bed Sit On The Floor?

If your existing headboard doesn’t have a bed frame, you can set it up directly on the floor with Sleep Number’s sturdy plastic modular bases.
