King Split Head Foam All
Foam mattresses here are all-foam beds without memory foam. They use responsive, high-resilience or gel foam layers over a high-density foam core, for a buoyant feel that is quiet, light and keeps movement to a minimum. Prefer the slow, contouring feel of memory foam? Choose Memory Foam instead.
