For a better night's sleep, the Kingsdown Sandsbury mattress offers a supportive solution made from quality materials. Precisely layered comfort materials in Kingsdown's Vertical Zoning design bring advanced pressure relief. Created to absorb heat, a luxurious quilt cover features high loft fiber with gel foam for soft cushioning that helps sleepers stay cool. A thick base layer cradles and reinforces the innerspring unit, consisting of individually wrapped coils that flex independently to reduce motion transfer for a deeper sleep. 10 Year Non-Prorated Warranty
