Mechanism for shifting a bed between horizontal and upright positions includes a pair of spaced apart vertical lift means coupled to opposite sides of an adjacent end of the bed and means for fastening the mattress to the headboard. Operation of the lift means draws the bed to a fully vertical position with the bed being between the lift means and being flat against a wall. Support structure for the remote end of the bed includes rollers on pivoting legs which swing into alignment with the bed as the vertical position is approached and which swing outward as the bed is lowered. Continued lowering of the bed causes the legs to pivot past a perpendicular position whereby the legs are inclined when the bed is fully lowered and contact a stop to securely support the remote end without requiring any manual manipulations thereat.
