Motion Isolation 3 – Customers note that Sleep Number Classic Series mattresses can absorb and minimize motion transfer to a significant extent.
Off-gassing 5 – Airbeds tend to produce less odor than other mattress types – and according to owners, Sleep Number Classic airbeds are no exception.
Conforming 3 – Conforming ability varies for airbeds in the Sleep Number Classic Series, but most owners say pain and pressure relief is fair or better.
Sex 2 – Sleep Number Classic airbeds feature a small trench between the air chambers that runs down the middle of the mattress, creating an uneven surface that can negatively affect sex.
Temperature Neutrality 2 – Sleep Number Classic airbed owners claim that their mattress sleeps fairly cool.
Edge Support 2 – Sleep Number Classic airbeds offer some edge support, giving them a slight advantage over memory foam and latex models, but sinkage, where people sit, has been reported.
Noise 2 – Sleep Number Classic owners claim that the Firmness Control system produces a fair amount of noise when air pressure levels are adjusted, but the mattress itself is fairly quiet.

Bed Buddy Report | Findings |

All Sleep Number mattresses offer customizable firmness ranges, and these ranges vary by model. Please note that most Sleep Number models share the same support core construction, which features two air chambers that can be adjusted using the Firmness Control function. The only exception is the IT bed, which features six individual air chambers. A breakdown of firmness options, layer dimensions, and components for all current Sleep Number mattresses is included in the table above.

The line of Sleep Number mattresses are all high quality selections, with the main components being air chambers which can customize the bed to be more plush or more firm based on the body composition and sleep preferences of the sleeper.  Many of the models also have sleep tracking abilities built in as well

The Sleep Number Classic line is offered in two models, the c2 as well as the c4.  The c2 is designed with a 2” polyfoam comfort layer while the c4 is equipped with a 3” polyfoam comfort layer.  Our tests found that that the entry level line performs quite well for someone looking for that firmness customization at their fingertips.


What Type of Sleeper Is Best Suited for a Sleep Number Mattress? 

Based on my customer feedback, the Sleep Number mattresses have received the following grades among sleepers of different weights and preferred sleep positions. Please note that these ratings are subjective, and that everyone has varying experiences on different mattresses. Sleeper comfort and spinal support are the most important factors when it comes to selecting a mattress.

As you can see, the Sleep Number line of mattresses are great for just about any sleep position your ability to dial in the firmness. When dealing with the technology involved with a performance mattress such as Sleep Number, it could be prone to issues


My testing process found the Sleep Number line should also be great for you if…

  • You’re interested in numerous options from one brand
  • You want the ability to customize every aspect of the mattress
  • You aren’t afraid to spend above industry average

We’re your Bed Buddy!!

Our mission is a simple one: We want to help you get incredible sleep, like a good sleep buddy should. And how you might ask? By not only conducting extensive research into the subject itself, but by personally testing out the thousands of mattresses on the market that claim to improve the quality of your slumber.

We really sleep on our mattress research by testing each for at least a hundred sleeps! We do not just compare features like review blogs, nor collate others’ online reviews, nor do a brief test of one to seven nights. No, our research includes a one hundred consecutive sleep test, so we can say, ‘Yup, this is what we found, because we really slept on it!’

We have no affiliation with the companies we feature, and any advertisements that appear on this website not at our discretion. They are there to keep the slumber party going. The Bed Buddy team takes incredible pride in the work we do. We hope that the reviews, news, and sleep information can help you on your personal journey for better sleep. And the job is fun – it’s not all naps! … sometimes… We love creating content that you enjoy, whether it’s on our site, or our newsletter, which you should sign up for.
