Abstract: An article of furniture is provided which can be transformed easily from a bed to a futon or a chaise lounge. The article of furniture is formed of a stationary, generally U-shaped upright support having a head frame with opposing ends from which side frames extend in mutual parallel alignment. A base frame assembly is mounted upon wheels or other roller elements and is comprised of a plurality or articulated frames, including a seat bench frame located remote from the head frame of the stationary support, and at least an intermediate seat back frame hinged to the bench frame. Preferably, a proximal back frame is also provided which includes within its structure a backrest that may be raised or lowered when the unit is used as a chaise lounge. The article of furniture is provided with rollers on each side of the stationary support near the distal extremities thereof. Cam latches are provided on opposing sides of the seat frame in longitudinal alignment with the rollers.
