Product information
Product details
Enjoy balanced quilted comfort with gel swirl memory foam and wrapped-coil support underneath. Best for sleepers who prefer a medium mattress with a cushioned top and a coil-spring system. This 12-inch mattress features cooling fabric, a Hyper-Cool layer, gel swirl memory foam, and high-density comfort foams. A DynamicEdge wrapped-coil system supports the comfort section, so the construction is coil-supported rather than entirely foam. Cooling materials are designed to help manage warmth near the surface. Available in Twin, Twin XL, Full, Queen, King, and California King. Its medium comfort build offers a middle-ground option between the firm and plush versions of the quilted Grace mattress.
