Construction & materials

	Cocoon by Sealy	Polysleep
Layers	Perfect Fit Memory Foam, Personalized Comfort, Essential Support Foam	Viscoelastic Hybrid Foam, Support Foam, High-Density Support Foam, Proprietary Support Frame, Liquid repellent cover.
Cover	Our premium stretch-knit fabric cover with spun poly fibers that’s breathable and durable with a soft feel.	The cover gives you a delicate, soft feel to lie on. It is also liquid repellent to avoid any accidents. The sides are made of mesh, which allows the mattress to be more breathable.
Machine-washable cover	No	Yes
Ergonomic handles	No	No
Comfort	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.	The ventilated viscoelastic hybrid foam is anti-microbial and prevents any moisture from accumulating. The top layer allows air to circulate, keeping you cool while adapting to your body. It identifies the pressure points, reduces the temperature and the firmness of these points in seconds only.
Support	Choose our soft layer for a cozier, more "in-the-bed" feel. Choose our firm layer for a sturdier, "on-the-bed" feel. Engineered to be highly durable and resilient. We’ve tested it, and we know it bounces back every time.	An element that makes this mattress truly unique is the proprietary support frame. This keeps the mattress from flattening out when you sit along any of the edges and helps to reinforce the structure. The support layer serves as a transition between the top layer and the base. It is designed for your comfort and provides full body support to ensure a better sleep. The first layer, or base, of the ultimate mattress is built with high-density foam and acts as a boxspring, while providing unparalleled reinforcement. It adds durability, strength and comfort without feeling too firm.
