Uniting cooling gel foam and a body-contouring innerspring unit, the Kingsdown Inspiration Firm mattress offers a restorative sleep experience with firm support. Offering maximum 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 a thick layer of gel infused memory foam combined with high loft fiber, delivering enhanced support while absorbing heat for cool cushioning at the surface that helps maintain a deeper sleep. A high-density foam encasement provides superior edge support for a complete edge-to-edge sleeping surface. 10 Year Non-Prorated Warranty.
