Does the Sealy Essentials work on an adjustable base?

Yes. The Essentials Tight Top is rated for adjustable bases. Its 600 pocketed coils and 2.5 inches of comfort foam flex at the head and foot rather than fighting the frame, so raising your head or legs works smoothly. It also sits well on a platform bed, a slatted base with gaps under 3 inches, or a solid foundation. Firm, even support underneath keeps the coil system performing.
