Bed Buddy Reporting On: Cocoon Chill by Sealy Mattress

Our research includes a 100 consecutive sleep test, so we can say, ‘YUP, this is what we found, because we really slept on it!’

All the details


6 (Firm)

WARRANTY 10 Year Limited
Durability 2 – Durability appears to be average for both Cocoon mattress models, but Cocoon by Sealy launched in March 2016 and the overall lifespan for these mattresses has not been fully assessed.
Motion Isolation 4 – According to owners, the Cocoon Chill absorbs and isolates motion transfer to a significant extent.
Off-gassing 2 – Like most memory foam models, Cocoon mattresses produce some off-gassing odors when unpackaged — but the smells will usually dissipate within one or two days.
Conforming 4 – Owners report that Cocoon mattresses conform very closely and relieve a fair amount of pressure; two available firmness ratings accommodate sleepers with different contouring preferences.
Sex 2 – Owners with ‘Firm’ Cocoon mattresses say they are somewhat responsive and bouncy, but the ‘Soft’ mattresses are not responsive enough for most couples.
Temperature Neutrality 3 – Despite the claims, owner experiences show the cocoon chill mattress doesn’t regulate temperature better than other all foam models.
Edge Support 1 – Cocoon by Sealy mattresses offer little to no edge support, and premature sinkage has been reported along the edges where people tend to sit.
Noise 5 – The Cocoon Chill is virtually silent when bearing weight.

Bed Buddy Report | Findings |

Cocoon by Sealy offers two different mattress models.  The Cocoon Classic and Cocoon Chill are constructed with a comfort layer of memory foam and a support layer of polyfoam, and are available in two firmness options.  The difference between the two models is the cover.  The Classic’s cover is constructed with a blend of polyester and cotton, while the Chill is equipped with a polyester-cotton stretch-knit cover containing phase-change material (PCM) to be cool to the touch.

In my review of the Cocoon mattresses, I found that motion was really well isolated while someone was moving around on the mattress. The Phase Change Material was definitely cool to the touch which is a nice change of pace from other heat trapping foam mattresses.

Cocoon by Sealy mattresses are available in two different firmness ratings: ‘Soft,’ which corresponds to a 4 (or ‘Medium Soft’) on my 1-10 Firmness Scale; and ‘Firm,’ which corresponds to a 6 (or ‘Medium Firm’). The Cocoon Classic and Cocoon Chill share the same construction, but both models have different covers. A full breakdown of mattress layers and measurements is found in the table below.

I know everyone sleeps differently, but I recommend big sleepers going with the ‘firm’ model for the needed support while lighter sleepers go with the ‘soft’ option.

What Type of Sleeper Is Best Suited for a Cocoon Mattress?

Based on a bunch of feedback from customers of different weights and preferred sleeping positions, I’ve gathered some ratings for the Cocoon Mattress. Keep in mind they’re all subjective and their experiences won’t be the same as anyone else’s. The most important things to think about when buying a mattress is comfort and back support.

The Cocoon is clearly a good choice for side sleepers at any bigness based on both firmness options and is especially great for back sleepers. I don’t want to recommend the Cocoon’s soft option to big sleepers because the support won’t be good enough, but the firm one should be great. The Phase Change Material is cool to the touch but if the mattress is fitted with a protector and sheets, you won’t actually be able to take advantage of it.

My testing process found the Cocoon should also be great for you if…

  • You’re looking for an affordable memory foam mattress.
  • You love the feel of memory foam – sleeping more “in” than “on” a bed.
  • You tend to sleep hot and want to take advantage of phase change material
  • You sleep with a partner and want to limit the movement you feel on the bed.

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?

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.
