ABSTRACT:
A mechanism for a chair or sofa which is convertible into a bed comprises a fixed frame to which is pivotally attached an articulated movable frame made up of three sub-frames a first of which is pivotally connected at one end to the fixed frame, a second of which is suspended within the fixed frame by links and levers attached to the first sub-frame, and the third of which is pivotally attached to the first sub-frame. When the mechanism is folded up for use as a chair or sofa the second sub-frame lies below the first and within the fixed frame. When the mechanism is opened out as a bed the first sub-frame is turned to a horizontal position and the second sub-frame is raised to the same horizontal level thereas by the linkages and lever systems from which it is suspended.
