Firm and supportive with extra cushioned comfort, thanks to its Euro pillowtop design, the Sealy Performance Crystal Sand with exclusive Posturepedic technology creates a restorative sleep environment ideal for quality rest. Sealy's exclusive Posturepedic technology provides zoned support where you need it most: in your core and lumbar regions. Featuring quality Sealy Response Coils, offering deep down support where you need it most, this mattress has a cushioned firm feel. Directly above the innerspring system is a layer of SealySupport Firm Foam, while SealyCushion Extra Soft Foam in the pillowtop layer provides addition cushioned support. Meanwhile, SealyCushion Air Foam and SealyCool Gel Foam at the mattress surface conform to your body, relieving pressure points and dissipating excess heat for a cool, refreshing feel. The SolidEdge HD System reinforces the mattress perimeter, offering more usable sleep space and an easier transition in and out of bed. 10 Year Non-Prorated Warranty.
