ABSTRACT OF THE DISCLOSURE A combined chair and bed which can be utilized selectively as a chair and a bed comprises a frame assembly, a seat assembly including a back rest, a leg support and a seat hinged at one side edge to the back rest and at the oppo- site side edge to the leg support, and at least one link mechanism operable to set the combined chair and bed in selec- tive one of chair and bed modes. While the seat assembly is mounted on the frame assembly through the link mechanism the link mechanism comprises a fulcrum about which the back rest pivots accompanied by an angular movement of the hinge between the back rest and the seat about the same fulcrum, thereby shifting the seat selectively upwardly and downwardly depending upon the direction of the pivotal movement of the back rest and a pair of links which, when the back rest is moved to the laid-down position, are erected to support the seat in flush with any one of the back rest and the leg sup- port. A transmission system for transmitting the movement of the back rest to the leg support is also included. -19-
