Abstract: A bed assembly is disclosed for use within a moving vehicle which vehicle includes a base support floor and a plurality of side wall members. The bed assembly includes a frame adapted to support a mattress and which has a generally rectangular perimeter. A plurality of attachment members are secured to the vehicle and are spaced about the perimeter of the frame. A plurality of tension elements interconnect the frame and the attachment members. Finally, a plurality of adjustable shock absorbing and dampening devices interconnect the frame and the vehicle base support floor to provide vertical support to the frame. The shock absorbing and dampening devices are aligned angularly relative to the frame to cooperate with the tension elements to dampen the fore-and-aft, lateral and vertical motion of the frame relative to the vehicle base support floor and side wall members during movement of the vehicle.
