ABSTRACT OF THE DISCLOSURE A bunk assembly for supporting a mattress above the floor of a sleeping compartment of a truck has a lower frame the longitudinal axis of which extends transversely of the corresponding axis of the truck. Corner supports attach the lower frame to the compartment floor and allow the frame to reciprocate to a limited or controlled extent in direc- tions towards the front and rear of the vehicle. An upper frame for supporting the mattress is secured to the lower frame by corner springs which absorb vertically imposed shock loads. Opposite ends of the lower and upper frames are interconnected by hinges which allow the latter frame to move only longitudinally of the former frame. Resilient braces also interconnect the two frames to further limit the folding action provided by the hinges which is resisted by the springs.
