King Split Head Foam Core Default Category

Foam core mattresses have no springs. The support comes from a core of high-density foam, with comfort layers of memory foam, gel foam or responsive foam on top. Foam absorbs movement, so a partner turning over is hard to feel, and with no coils the bed stays quiet. Use Mattress Type to choose between Memory Foam and Foam for the feel of the layers.
