A sofa bed is provided with a backrest and a bed/seating portion supported by a frame. The frame has a back member with inverted "L" slotted posts, the slots receiving pins on connection member's ends that are pivotally connected to the backrest. Manipulation of the backrest causes the pins to rest in a horizontal slot portion, the connection members then causing the backrest top to be spaced from the frame back member into a forward position in which it is oriented to serve as a seat back for an occupant seated on the bed member. Positioning members brace the backrest bottom against the frame. Further manipulation causes the pins to descend into a vertical slot portion allowing the connection members to pivot such that the backrest is in a substantially flush position against the frame back. Lid members and permanent and removable side portions are provided, with attachable cushioned armrests.
