Some furniture works a double shift, and this twin metal daybed does it with a little romance. Rounded arch detailing sweeps across the curved backrest and both armrests, three sides of picket-style arches that read more like a vintage garden gate than a plain guest bed. In its black finish, the 76.5 x 41 x 40 in frame settles into a living room as a slim sofa, armrests standing 29 in tall to prop a pillow for reading, chatting, or an afternoon of Tv across the 75 x 40.5 in deck.Come nightfall, the frame turns practical. Two sets of 13 heavy-duty metal slats carry a 3 to 5 in twin mattress, sold separately, with no box spring required, supporting up to 440 lbs on the daybed. Below, a 73 x 40 x 4 in trundle rides on four lockable casters: pull it out and a second bed rated for 330 lbs appears for sleepovers, lock the wheels and it stays put until morning, slide it back and the room returns to normal. A middle support leg secured by a hook-and-loop fastener braces the center of the daybed and folds away so the trundle glides freely past. For apartments, guest rooms, and any bedroom that moonlights as a lounge, it offers two sleeping spots in the footprint of one.
