This twin metal daybed works as a sofa during the day and opens into two beds at night. Rounded arch detailing runs across the backrest and both 29-in armrests, giving the black and gold frame a lighter look than a boxed sofa. Thirteen steel slats support the top deck for up to 440 lbs, and thirteen more support the pull-out trundle for up to 330 lbs. Both decks take a 3-in to 5-in twin mattress with no box spring needed. Four lockable casters let the trundle roll out and stay put, and an extra center leg secures with a hook-and-loop strap. Assembly is required.
