A folding sofa bed includes a back, a seat and a forward extension moveable between a generally horizontal, planar array when in the bed configuration and a sofa configuration, wherein the seat and back are generally transverse and in generally horizontal and vertical orientations, respectively, and the forward extension is disposed below a forward edge of the seat portion in a retracted position. Pivoting linkage couples the back and seat as well as the seat and the forward extension, with locking linkage and stops provided for (1) maintaining the extension in the extended, upraised position; (2) maintaining the seat and back in the horizontal, planar configuration; and (3) maintaining the seat and back in fixed relative orientation when in the sofa configuration. The folding sofa bed is easily moveable between the two configurations by merely grasping and moving a forward edge of the seat in an upward, forward direction for the bed configuration or in a upward, rearward direction for the sofa configuration, with the forward extension also easily moveable between the two configurations. A pair of legs automatically deploy when the sofa bed is folded to the bed configuration to provide support for a forward portion of the seat as well as for the forward extension.
