The Serta Sequoia mattress is designed to provide a cool, supportive, and pressure-relieving sleep experience. CoolFeel™ Tencel Fabric and gel-infused foams help wick away heat and moisture while maintaining a comfortably balanced sleep temperature. GelPlus® memory foam gently contours to the body for enhanced pressure relief and long-lasting comfort, while the 3-zone pocket coil system with reinforced lumbar support promotes proper spinal alignment and minimizes motion transfer. Best Edge® Foam Encasement adds edge-to-edge stability and maximizes the usable sleep surface for lasting comfort and support.
