Cocoon Chill Hybrid Mattress Review: Our Unbiased Review
The Cocoon Chill Hybrid is composed of adaptive foam layers over a bed of supportive coils. This creates a soothing balance of cushioning and pushback, and motion isolation is above average compared to the competition.
- Memory foam comfort layer provides contouring and pressure relief
- Hybrid design adds bounce and stability to the foam layers
- Phase change material in the cover is designed to promote a neutral temperature
- Feels too soft for most sleepers over 230 pounds
- “New mattress smell” can persist for a few days after unboxing the mattress
Sealy is one of the best-known names in the mattress industry. The company started in 1881 and continues to be part of Tempur Sealy International, one of the largest mattress manufacturers in the world.
The Cocoon Chill Hybrid is part of a unique product line from Sealy for people who want to buy a mattress online. This 12-inch mattress feels medium firm (6) and relieves pressure thanks to a memory foam comfort layer.
Our testing team took the Cocoon Chill Hybrid for a spin to discover all of its strengths and weaknesses. We analyze its performance and also break down the materials, construction, pricing, and sizing of the Cocoon Chill Hybrid Mattress.
SMART MATCHING
Is the Cocoon Chill Hybrid Right for You?
Use the filters below to see how well the Cocoon Chill Hybrid lines up with your unique needs. We'll also give you a couple other recommendations based on your answers.
TEST LAB RATINGS
How the Cocoon Chill Hybrid Scored
Motion Isolation7.0/10
With a top layer of memory foam, the Cocoon Chill Hybrid effectively isolates most motion. Because there is some bounce from the pocketed coils, you may still notice a few vibrations. But the movement has to be pretty exaggerated for it to feel disruptive, which means most couples can share this mattress without a problem.
Colin Simpson, Product Research Manager: Some vibration carries across this mattress surface, but unless you’re a light sleeper or your bed partner plans to be jumping up and down on their side of the bed, I don’t think it’s going to interfere too much with your sleep.
Pressure Relief7.5/10
“There’s a nice balance of cushioning and pushback on this mattress. It results in above-average pressure relief for side sleepers under 230 pounds, but the spinal support may not be as great for other sleepers.” – Jeremy
Like many hybrid models that use memory foam, the Cocoon Chill Hybrid’s conforming can help ease sharp pressure points by adapting to a sleeper’s weight.
With a medium firm (6) feel, that contouring can result in quality support for a wide range of sleepers. But our testing found that the Chill Hybrid’s ability to relieve pressure was lower for many stomach sleepers and people over 230 pounds.
Temperature Control7.0/10
In our temperature tests, the Cocoon Chill Hybrid maintained a neutral temperature about as well as most other hybrid mattresses.
While its memory foam can retain heat, the cover’s phase change material is engineered to help dissipate that heat. Airflow through the coils can also prevent excessive heat buildup.
Nevertheless, hot sleepers may prefer a mattress without memory foam. People over 230 pounds may also sleep hotter on this mattress since the foam will contour more tightly against their skin.
Mary Fenton, Head of Product Content: I didn’t encounter any issues with sleeping hot on the Cocoon Chill Hybrid. Its temperature stayed pretty neutral, especially since I didn’t find myself sinking too deeply into the memory foam layer.
Edge Support7.0/10
Reinforced edges in the Cocoon Chill Hybrid’s support core add stability to the perimeter of this mattress, counteracting some of the sinkage from the top layer of memory foam.
Our team didn’t find edge support to be lacking, but they did note that the most significant complaints about the edges came from people over 230 pounds who experienced more pronounced foam compression.
Colin Simpson, Product Research Manager: Most people should be able to sleep comfortably near the edge of this mattress. When sitting on the edge, the foam compresses a bit more than you’d like, but it’s comparable to a lot of other hybrid mattresses out there.
Ease of Movement6.5/10
The Cocoon Chill Hybrid rates as average for ease of movement. On one hand, the memory foam can at times feel like it’s holding the body in place. On the other hand, the coils give the mattress bounce that facilitates movement.
Our team found that these largely cancel each other out, so movement isn’t extremely easy or extremely difficult. There may be more challenges for people with a higher body weight who sink more deeply into the foam. Combination sleepers over 230 pounds may prefer a mattress with higher scores for ease of movement.
Jeremy Klein, Product Testing Manager: I didn’t feel stuck in place, but there was a bit of resistance when I wanted to turn from one side to the other. It may be more of a problem for combination sleepers who frequently adjust their position.
Durability7.0/10
Thanks to its coil support core, the Cocoon Chill Hybrid should hold up a bit longer than the average mattress. Hybrid mattresses generally provide more longevity, as coils maintain their structure better than foam alone. That being said, the comfort layer combines memory foam and polyfoam, both of which may begin to soften or sag after seven to eight years.
HANDS-ON TESTING
Testing Team Takeaways
To test the Cocoon Chill Hybrid Mattress, we had three people on our testing team each take the bed home with them for one week. Here are their initial observations.
Jeremy Klein
Product Testing Manager · Side sleeper · 160 lbs.
Side sleeper · 160 lbs.
The Cocoon Chill Hybrid is right in the sweet spot for me. It has the right amount of cushioning for my shoulders and hips, but the coils give it enough pushback that I didn’t feel swallowed up by the memory foam.

At times, I felt the sink was a bit too much. I think that will be a problem for most sleepers with a higher body weight. In most categories, the Cocoon Chill Hybrid was fine, but there’s no standout part of its performance.
Mary Fenton

I found the mattress to be most comfortable when sleeping on my side. It was good enough when on my back or stomach, but, like Colin said, I think its firmness level may be lacking for a lot of back and stomach sleepers.
Who it Fits
Fit by Sleep Position and Body Weight
Sizes, dimensions and weights
Side Sleepers
In our Test Lab, we found that the Cocoon Chill Hybrid works best for side sleepers who weigh between 130 and 230 pounds. Its memory foam layer adapted to accommodate their hips and shoulders so that the spine stayed in a more neutral position. Side sleepers under 130 pounds also liked the feel of the mattress, but some felt it was a touch too firm.
Side sleepers over 230 pounds found that their joints pushed too far into the foam, which reduced both comfort and spinal support.
Back Sleepers
Among back sleepers, the Cocoon Chill Hybrid is best for those whose body weight is under 130 pounds. The medium firm (6) feel was enough to hold their hips in line with the rest of the body while lightly cushioning the natural curve of their lower back.
Some back sleepers between 130 and 230 pounds also complimented the balanced feel of the mattress, but many said that there was too much sinkage to have optimal support. That was also a common complaint from back sleepers over 230 pounds.
Stomach Sleepers
The Cocoon Chill Hybrid isn’t a great fit for most stomach sleepers. While our testing team found that it’s workable for those under 130 pounds, stomach sleepers generally get better support from a firmer mattress. When firmness is lacking, the hips and belly can sink into the foam, drawing the body into a U-shape that can strain muscles in the back.
