The Cocoon Chill Hybrid Mattress is a hybrid model that combines a foam comfort system with a pocketed coil support core. It has a medium firm feel, rating around 6 out of 10, which is in the average range most sleepers tend to prefer.
Four distinct layers make up the mattress. The comfort layer uses 1 inch of Perfect Fit memory foam, and the transition layer uses 2.25 more inches of the same material. This premium foam adapts to the sleeper’s shape to cushion the body, relieve pressure, and support the spine.
The support system uses 8 inches of coils that add bounce and breathability. Each spring is individually wrapped in fabric to reduce the spread of motion and allow them to move independently for targeted support. The perimeter is lined with narrower coils to give the edge a sturdy feel. A final .75-inch layer of polyfoam rests at the base for durable, resilient structural support.
Proprietary phase change material in the stretch knit mattress cover is engineered to absorb and redistribute heat to prevent dips and spikes in your overnight temperature while remaining cool to the touch.
The Cocoon Chill Hybrid Mattress uses four layers encased in a phase change material cover. Both the comfort and transition layers are made up of Perfect Fit Memory Foam, and the core consists of pocketed coils with a reinforced perimeter. A final base layer of polyfoam supports the coil system.

The Cocoon Chill Hybrid Mattress is less than the average price of a quality hybrid model. Since it includes similar cooling components to many higher-priced options, it’s a good value for those looking for strong temperature regulation without a steep price-point. This model is available in the six standard mattress sizes.

Side sleeping often leads to pressure buildup around the hips and shoulders due to the width of these critical areas. A mattress that molds to the sleeper’s body can help spread out their weight to relieve pressure. Thanks to its two layers of memory foam, the Cocoon Chill Hybrid shapes to a side sleeper’s curves for balanced support and conforming.
With its medium firm feel, the Cocoon Chill Hybrid should be exceptionally comfortable for side sleepers who weigh below 230 pounds since they should sink in the right amount for pressure relief and spinal support. This model should also relieve pressure points for those who weigh more than 230 pounds, though some in this weight group may struggle to keep their spines well aligned.
Sleeping on the back is usually conducive to good spinal alignment as long as the mattress lets the hips sink in just a little without sagging. The Cocoon Chill Hybrid’s memory foam comfort and transition layers combine contouring and support, which should gently cradle a back sleeper’s hips while preventing excessive sinkage. The supportive coil layer further limits sagging.
As a medium firm model, the Cocoon Chill should easily adjust to the shape of a back sleeper who weighs under 230 pounds to support proper spinal alignment. The hips of some back sleepers who weigh more than 230 pounds could sink in farther than ideal and put some pressure on the lower back.
Most people carry much of their body weight around their hips and bellies. When sleeping on the stomach, this weight often pulls the middle of the body too deeply into the mattress, putting pressure on the lumbar area. The Cocoon Chill Hybrid’s memory foam comfort and transition layers soften the feel of the sleep surface while providing support, making the bed comfortable for many stomach sleepers.
Those who weigh below 230 pounds will likely experience the best mixture of cushioning and support. Stomach sleepers who weigh under 130 pounds shouldn’t struggle to keep their spines well aligned, but the medium firm feel could seem a bit too sturdy to them. Individuals who weigh over 230 pounds may have more difficulty keeping their spines well aligned due to sinkage around their hips and stomachs.

While many Sealy products are available through third-party retailers, including furniture, mattress, and department stores, the Cocoon Chill Hybrid Mattress is currently sold exclusively through the Cocoon by Sealy website. It is available within the United States.
Sealy typically processes orders within 48 hours on business days. Mattresses are delivered via UPS and typically arrive in 5 to 7 days. Standard ground shipping is free within the United States, and expedited shipping may be available for an additional fee. Customers receive a tracking number so that they can anticipate the date of arrival.
The mattress arrives at the owner’s home compressed, wrapped in plastic, and encased in a box. The delivery team leaves the package at the door or wherever you receive large items, and the customer usually does not need to be home for delivery. It is the owner’s responsibility to move the package into their room of choice and set it up. To unpack the bed, slide the compressed mattress out of the box, place it on the foundation, remove the tape to separate the wrapper, and let the mattress expand.
Sealy does not currently offer White Glove delivery or old mattress removal with the Cocoon Chill Hybrid Mattress.
The company recommends trying the bed for at least 30 nights to adjust. If you’re not satisfied with the mattress, Sealy will try to resolve any issues. If you’re still unsatisfied during the first 100 days, you can return the mattress for a full refund of the purchase price. Sealy will arrange for its pickup and donation.
Owners who bought their Cocoon Chill Hybrid from Sealy or an authorized retailer are eligible for a 10-year limited warranty. This policy covers faulty workmanship and materials, including visible indentations greater than 1 inch and physical flaws that cause the mattress cover to tear.
Should Sealy determine there is an eligible defect, it will elect to either repair or replace the mattress. The purchaser is responsible for transportation costs.
