Offering pressure relief, it features vertical zoning with precisely layered comfort materials and individually wrapped coils that flex independently to reduce motion transfer between sleep partners. A luxurious quilt cover includes gel foam and high loft fiber to deliver enhanced support while absorbing heat for cool cushioning that helps you maintain a deeper sleep. Latex lumbar support magnifies pressure relief and maximizes supportive comfort where you need it most. 10 Year Non-Prorated Warranty.
