Not only does 4Sleep have 4 amazing layers (for extra comfort and support) as opposed to most having only 3, but our cover is like a performance shirt fabric, it wicks away moisture, is breathable, lightweight, and has "Cooling On Demand" technology that actually has built in gel to help keep you cool. We also offer our one of a kind “Side Edge Support” which prevents you from feeling you will roll off of your mattress. Finally, don’t listen to us, read the reviews!
