Continuous Coil Foam Core All
Continuous coil mattresses use coils that are linked together, either formed from one length of wire per row or joined with connecting wires, as in Bonnell and offset coil systems. Because the coils move as one unit, the bed has a classic bouncy feel, a firm and even surface, and holds up well over time. A dependable choice for back and stomach sleepers.
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.
