Hosting is simpler when the spare bed lives in a closet. This folding guest bed opens to a 75 x 38 x 16 in twin frame and collapses to just 38 x 15 x 41.5 in, small enough to stand behind a door or slide beside a wardrobe between visits, then roll back out when family arrives for the holidays.The included mattress measures 75.5 x 39 x 4 in and layers gel memory foam over a supportive base foam, so a guest gets real cushioning instead of a thin pad. Mattress retainers and a non-slip base keep it from shifting overnight, while the heavy-duty metal frame, metal slat support, and triangular bracing carry up to 485 lbs without creaking. Four universal casters make the 46.5 lb bed easy to roll across a room, and two of them lock so the bed stays where it is placed. The elevated frame allows air to circulate beneath the mattress and leaves the floor clear for cleaning. It suits apartments, guest rooms, dorms, and home offices that occasionally double as a bedroom. Assembly is needed.
