The Sealy Posturepedic Foam Lacey is a 13-inch firm mattress built from gel memory foam and sold in a California King size (84 by 80 inches). It is designed to work on an adjustable bed base, so the foam flexes with the frame. The gel layer is meant to pull heat away from the body while the firm core keeps the spine supported. As of November 4, 2026, the best new price is $1,459 at bigsonline.com, the only store listing it new.
