Cocoon Mattress Review
This Cocoon mattress review gives our opinion of this affordable online memory foam mattress introduced by industry leader Sealy. Sealy, also known officially as Tempur Sealy, is probably the most well known mattress company and is behind the most recognized brands Tempur-Pedic and Sealy that are sold in stores.
The Cocoon is the industry giant’s response to the Bed-in-A-Box industry that has emerged recently.

The Cocoon mattress is a memory foam mattress that is much more affordable than the more expensive Tempur Pedic brands sold in stores, and comes in two different models, the Cocoon Classic, and Cocoon Chill.
Check out our review of the Cocoon Chill and see what we think about this recent entry from the mattress industry powerhouse Tempur Sealy! Last updated
Construction and Materials
We received a Cocoon Chill in their soft firmness model. The Cocoon Chill mattress measures 10″ and uses a combination of 3 layers of memory foam poly foam and support foam.
- 2″ Top comfort layer – The top layer is made of 2″ of perfect fit memory foam, designed to provide the initial comfort to the mattress when lying down as well as hug and contour.
- 2″ Middle layer – This layer is made up of 2″ of poly foam and is designed to support the body and provide pressure relief and spinal alignment as well as transition between the top comfort layer and lower support layer.
- 6″ Bottom layer – This foundation layer is made of dense support foam. This provides the foundation for the mattress that is designed to work with the top layers to create great support.
The Cocoon Chill has a extremely soft cover that works to provide a cool surface and comfort as well. The cover is made of polyester and cotton and uses phase change material which aids in temperature regulation. The goal of phase change material is to provide cooling when you are hot, and heat when it is cool.
Firmness & Support
The Cocoon Chill comes in two firmness options, the soft and the firm. We tested the soft model, and felt that it comes in around a 5/6 out of 10 on the firmness scale (10 being firmness.)
As always, firmness is largely weight dependent, as I compressed the top layers more than Kaye did since I weigh considerably more than she does (230lbs vs. 115).
She felt it was a little softer than I did, as my weight tends to compress through the top comfort layers and rest on the underlying support layers which are much denser.
I personally didn’t feel that the Cocoon provided much support to me when sleeping, as my heavier weight caused me to compress through the upper layers quite a bit.
My weight was fairly distributed, but when I sat up in the bed, I sunk through the mattress and “bottomed” out when sitting up. The foam layers do a decent job of providing support during sleeping, but the layers seemed to compress quite a bit making the mattress feel a lot thinner than it appears.
The Cocoon Chill soft mattress is more on the medium to soft side for us. The layers of memory foam provide a bit of responsiveness and bounce without causing too much sinkage down into the memory foam as expected, but much more so than a mattress containing latex or other responsive materials.
The all foam construction provided a good degree of body hug and contour, which we personally are fans of given we like memory foam mattresses, without making us feel “trapped in the mattress” which is not good.
The softness of the cover combined with the initial soft response from the memory foam layers did make for a comfortable nights sleep, and this was shared by both of us.
As we are primarily side sleepers, the softer model of the Cocoon Chill felt great on our sides, and did not result in any hip or shoulder pain which some softer mattresses often cause.
The Cocoon Chill does a fair job of sleeping cool from the thin cover and presence of the phase change material designed to provide cooling.
Strangely, however, upon initially laying down on it the material in the top cover felt a little sticky and seemed to retain heat. When we put sheets on the bed, however, we did not feel any discomfort or stickiness that is often the case with all memory foam mattresses, and the Cocoon did a fair job in this respect.
We would rate the Cocoon mattress as about average in terms of not sleeping hot, not necessarily better than most memory foam mattresses in this regard, even for the “Chill” model.
Sinkage and Motion Transfer
In terms of sinkage and motion transfer, again with many of these mattresses it is highly dependent on sleeper weight. As I weigh considerably more than Kaye, around 230 lbs, I tend to sink a lot more into the mattress when sitting up or on the edge.
This was particularly true of the Cocoon. When sitting on it, I compressed almost all the way through the mattress.
Kaye did not experience this amount of sinkage as she weighs half of what I do. Nor did we experience the common phenomenon of her “sinking in a hole” or rolling towards me from the unequal weight difference on the mattress.
Overall, we felt that there was more sinkage than we would have liked with the mattress. My heavier weight sunk through quite a bit when sitting and at times lying down.
Edge support was minimal when my weight compressed the bed. Lying flat seemed to disperse the weight but at times when rolling over in the night I would feel the harder support layer through the compressed thinner comfort layer.
There was a decent amount of motion transfer when I adjusted positions during the night which again is to be expected from the weight differential. This is often a trade-off for us with a less firm mattress, as the firm ones are better at motion transfer but not as comfortable.
Smell / Off-Gassing
There was a small degree of off-gassing / smell but nothing overpowering compared to some other mattresses we have reviewed. We give the Cocoon Chill above-average marks in this category.
The Cocoon mattress is pretty standard when it comes to their warranty and support offerings. Most mattresses in this category share about the same offerings in terms of sleep trials and warranty, and Leesa is no exception here.

The Cocoon Chill Soft mattress introduced by Tempur Sealy does a good job of appealing to a wide variety of sleepers with a medium feel on average depending on sleeper weight.
The all memory foam construction does a good job of providing balance and pressure relieving support as well as a comfortable nights sleep. The mattress sleeps comfortable especially for side sleepers, however stomach or back sleepers may want to choose the Firm model.
It sleeps fairly cool due to the phase change material used in the cover compared to many other memory foam mattresses and is a decent choice for couples that may have different firmness preferences.
We did feel there was a degree of motion transfer and sinkage, especially for heavier couples or those with a significant weight difference.
All things considered, the Cocoon Chill is a good value in a mattress from the makers of Tempur Pedic at a fraction of the price of one of those in-store models. We hope that our Cocoon mattress review helped you in your next purchase decision!
