Sealy Adjustable Base Compatible Grey All Mattresses

Sealy mattresses are engineered for dependable, body-aligning support — many featuring Posturepedic Technology that reinforces the centre third where you need it most. Compare every option below by feel, size, and price.
These mattresses are built to flex with adjustable bed bases — bending smoothly at the head and foot without damage — so you can raise, recline, and find your ideal position. Compare every adjustable-base-compatible option below by brand, type, and feel.

Shop 200+ mattresses from Serta, Beautyrest, Sealy, Tempur-Pedic, Springwall, and Stearns & Foster at National Mattress — available in Single/Twin through King sizes from $99 to $6,640. Choose from innerspring, euro-top, memory foam, hybrid, and latex constructions in four firmness levels from extra firm to plush.
