King Split Head King Queen Split Head Full Size Limited Stock Mattresses Serta® Mattresses and Accessories
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.
These mattresses are down to their last few units — when they're gone, they're gone. Limited stock spans every brand and price point, from value foam to premium hybrids by Sealy, Serta, Beautyrest, Tempur-Pedic and our own NM line, so there are options here at every budget. The upside of limited stock is speed: because these beds are physically in our warehouse right now, they're ready to ship and can arrive fast — often as soon as the next day in many areas.
