Does the Sealy Cocoon work on an adjustable base?

Yes. This all-foam memory-foam bed is rated for adjustable bases and flexes easily at the head and foot, since it has no coils or rigid edge. Its slim 8-inch build articulates smoothly. It also sits flat on a platform bed, a slatted base with gaps under 3 inches, or a solid foundation. Any firm, continuous surface supports it; the foam just needs even backing underneath.
