Bed Frame Boxspring Adjustable Bases Double/Full Sealy® 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.

Sealy is a pioneering mattress brand known for its science-backed support and comfort, with over a century of quality craftsmanship behind it.

Shop Sealy across the Essentials, Cocoon™, Posturepedic®, Posturepedic® Plus, Posturepedic® Luxury and Posturepedic® Natural Origins collections, in single/twin through king. Every Sealy we carry is made in Canada with a 5- or 10-year manufacturer warranty, plus our 365-night sleep trial and price-match guarantee.
