“Great Mattress"
This is our second Cocoon mattress. Great mattress for the value. Fast shipping & just unwrap it & it's ready. My kids are hot sleepers like me so love the cooling feature.

What's Compatible?
Cocoon™ by Sealy mattresses need a solid, elevated surface to deliver comfort you can count on.
Pair your mattress with a power base for a personalized sleep experience. Plus, nearly unlimited head and foot positions to customize your relaxation routine.
Designed to remain solid and supportive, our foundations are made from high-grade wood, with a supportive structure constructed from high-gauge steel wire to give your mattress the flat, sturdy base it needs. Learn More.
Slatted foundations and platform beds can support a Cocoon™ by Sealy mattress. We require that the slats be at least 3" wide and no more than 4" apart.
Box springs are not compatible with Cocoon™ by Sealy mattresses as they need a solid base. Box springs are designed to "give" so a traditional mattress can support your weight. Learn More.
We do not suggest placing your mattress on the floor. Doing so may trap moisture underneath the mattress, damage, or invalidate your warranty.
