A three cushion convertible seat-bed is disclosed. First and second panels (12,14) are pivotally coupled to each other and are supported by a base (10) to form a seat bottom and a seat back in the seat orientation and to form side-by-side bed panels in a bed orientation. A third panel (16) is pivotally coupled with the second panel and forms a third bed panel in the bed orientation. A latch D secures the third panel relative to the base. A manual operating lever (22) operates the latch and the pull member (76) is adapted for manual actuation for folding the panels from the bed orientation to the seat orientation. The third panel includes a leg (20) for carrying the rear edge of the panel between the bed and seat orientation. An energy storage spring (224) is actuated to store energy by movement of the panels from the bed orientation to the seat orientation. An actuating lever (212) is coupled with the spring through an overcenter linkage (218) and is actuable for pushing the third panel toward the bed orientation upon unlatching of the latch.
