Double/Full mattresses measure 54" × 75" — fifteen inches wider than a twin, giving a single sleeper plenty of room to spread out. They suit teens, single adults, and smaller bedrooms or guest rooms, and work for couples who prefer a cozier fit. Compare every double/full option below by brand, feel, and price.
Clearance is where you'll find our deepest mattress discounts — open-box, floor-model and last-unit beds from premium brands like Sealy, Serta, Beautyrest, Simmons, Tempur-Pedic and iComfort, marked down well below regular price to clear space for new stock. Because these are one-of and limited-quantity items, the sizes and models change constantly and the best deals sell fast — when it's gone, it's gone. If you're hunting for a premium mattress at a bargain price and don't mind a floor model or an opened package, this is the place to start.
