Enjoy endless possibilities for restful sleep with the Chime 12 hybrid innerspring design that brings traditional coil support together with foam comfort for everyday bedrooms, guest rooms and new apartments. If you are comparing a memory foam mattress to a coil bed, this queen mattress with memory foam delivers the cozy contour many expect from a queen memory foam mattress while adding responsive wrapped-coil lift. Sized as a queen size mattress, it arrives in a box so you can carry it to the room, remove the plastic wrap and unroll with minimal hassle. Shoppers choosing between a queen size memory foam mattress and a hybrid will appreciate the ultra plush surface and lumbar gel layer designed for comforting, restorative support
