Collection: Full Size Futon Mattresses

Full size futon mattresses are a versatile choice when you want one piece that can handle both daily seating and regular sleep. Sized for a standard futon mattress in full size (about 54" x 75"), these designs give adults and guests enough room to stretch out while still fitting easily in most living rooms, studios, and home offices. Whether you’re upgrading a long-term sleeping setup or creating a more comfortable futon for occasional visitors, full size strikes a smart balance between space-saving and true bed-like comfort.

On a frame in the sofa position, a full size futon becomes a supportive sofa futon during the day and a roomy sofa sleeper futon at night. Solid wood full-size frames for futons turn your mattress into a durable futon bed couch that’s much more substantial than a typical metal frame or click-clack. In living rooms and dens, many people pair a full mattress with convertible pieces from our futon couches and sofa bed collection, so the same room can function as a lounge most of the time and a comfortable guest space when needed.

Full size futon mattresses are just as at home on solid wood beds or directly on the floor. Placed on a low slatted base from our natural platform bed collection, they work like a traditional mattress with a slightly more flexible, futon-like feel. For a more grounded setup, some sleepers use a full futon on layered tatami or coir foundations from our floor bed assortment, or mix and match with thinner Japanese futon mattresses (shikibutons) when building a hybrid japanese futon bed that can be folded and aired more easily.

Depending on the model you choose, your full size futon mattress may use natural cotton, wool, latex, or blended cores, letting you tune firmness and support for nightly use or occasional sleep. Many shoppers looking for an especially comfortable futon layer a full-size core with toppers from our mattress topper collection or protect it with breathable covers from the organic mattress protector range. If you’re trying to decide between a more traditional futon feel and a thicker hybrid, you can also compare options across the broader futon mattress collection to match your frame and room.
