Folded down to 16-in thick, this rollaway slides behind a door or into a closet gap that a bulkier guest bed will not clear, and a fixing strap holds it shut while it is stored. The 5-in mattress layers gel memory foam over high-density sponge, which is closer to a real bed than the thin pads shipped with most folding frames. Reinforced crossbars bring the rated load to 485-lb Four universal wheels move the bed, and retainers hold the mattress on the 75-in x 38-in deck.
