A chair bed for supporting an invalid, wheelchair-bound or non-ambulatory person, which includes a seat portion and a hinged backrest attached to the seat portion for adjusting the reclining angle of the occupant, with conventional main wheels, optional rear wheels and 350 degree pivotable front wheels for rolling operation and directional control. The arm rests of the chair bed are pivotally adjustable in two sections and in a preferred embodiment, the seat portion of the chair bed is fitted with a frontal circular recess. A latch element is also provided in the chair bed frame for engaging and locking the chair bed to a receiver mechanism located in close proximity to a conventional or specially designed commode, in order to facilitate movement by the non-ambulatory chair bed occupant to and from the commode.
