A futon frame is convertible between a bed position and a sitting position and includes a back portion and a seat portion. The back portion is oriented generally upright when the frame is in the sitting position and is oriented horizontally when the frame is in the bed position. The seat portion is hingedly attached to the back portion to permit relative movement of the back portion with respect to the seat portion. A connector releasably connects the back portion and seat portion to cause the back portion to move on movement of the seat portion in a first direction about a pivot point. A support supports the back portion with respect to a supporting surface and the back portion includes a pair of opposed outer edges. A pair of first pins are provided, each connected to one of the outer edges of the back portion and the support and a pair of first slots, each in the other of the outer edges of the back portion and the support are provided for constraining movement of the first pins within respective first slots. Each first slot includes a contact surface preventing upward movement of the pins with respect to the first slots when the frame is in the bed position and curved such that the pins are releasable from the contact surface upon movement of the back portion in a pivoted direction, when the frame is moved from its bed position to its sitting position.
