This upgraded hybrid mattress features Sealy's highest coil count and a thick layer of premium, pressure relieving memory foam. The SealyCool™ gel foam promotes a cooling environment and helps cushion, delivering comfort and support with a firm feel, while the densely packed coil system reinforces the center third of the mattress, delivering trusted, targeted support where you need it most—your back and core. The DURAFLEX™ pro coil edge system consists of densely packed coils surrounding the edge of this mattress for added durability, more sleeping area, a solid seating surface and better flexibility when paired with an adjustable base. Plus, the cool to the touch version of Sealy's stretch knit cover features cooling fibers for comfort and Surface-Guard Technology™ which protects the mattress surface from odors and stains caused by bacteria and common allergens.
