Firmness info	The Cocoon Chill is a medium firmness, about a 6 on the firmness scale. We've found that most sleepers prefer a mattress that's fully supportive but not too firm, so we created a mattress with our Perfect Fit memory foam that adapts to your unique body size, shape and sleep position.	We consider our mattress a 6 on a scale of 1-10 with 10 being the firmest.

Construction & materials

	Cocoon by Sealy Chill	PerformaSleep
Layers	Perfect Fit Memory Foam, Personalized Comfort Layer, Support Foam.	2" CopperCool Gel Foam, 2" Enersorb Foam, 7" Thick High-Density PerformaBase Foam.
Cover	Our premium stretch-knit cover is infused with a proprietary "Phase Change Material" that absorbs and dissipates heat for a refreshing, cool to the touch surface.	A luxurious cover made with TENCEL. Cellulose fibers in TENCEL fiber fabric wick moisture away while staying impeccably soft.
Machine-washable cover	No	No
Ergonomic handles	No	No
Comfort	A top layer of memory foam helps reduce the amount of movement from your sleep partner. The Soft model reduces a bit more motion transfer than the Firm model. Phase Change Material (PCM) absorbs your body heat leaving you with a cool to the touch mattress experience.	The PerformaSleep mattress was specifically designed for people with an active lifestyle that need to recover fast. The CopperCool Technology infused into the top layer of the mattress help dissipate excess body heat, give a variable support, and eliminate any moisture. Athletes tend to be denser, therefore they need more support. They also tend to be hot-natured, and need a cooler mattress. In the PerformaSleep mattress, we give our athletes just that. The unique construction and technology of the mattress allows you to sleep cooler and better by elevating any pressure points in the mattress. This in return gives you a better night's sleep which in result will allow you to do better in your everyday activities. The CopperCool technology in the mattress wicks away excess body heat allowing you to sleep cooler throughout the night. When you are laying on your mattress your body will naturally compress the foam and in result the copper and gel particles infused throughout the top layer of the mattress start to coalesce together allowing for the heat to travel away from the body, from particle to particle. Our foam components also have higher airflows than most mattresses on the market today allowing for better heat dissipation.
Support	Our high-quality memory foam adapts to your body size, shape and sleep position to ensure a great sleep no matter which feel is right for you. Support Foam base layer engineered to be highly durable and resilient. We've tested it, and we know it bounces back every time.	The PerformaSleep Enersorb material also gives you that bounce you need to help you move freely throughout the bed and not feel like you are stuck in a hole as with traditional memory foam mattresses. The Enersorb material gives you the same comfort, conformity, and pressure relief as memory foam but without the slow recovery. This is what gives you that bounce and allows you to move freely throughout the bed. Our Enersorb material is also more breathable than memory foam or latex allowing for better heat dissipation.
