ABSTRACT:
An adjustable articulated bed manufactured in seven or so components for packing in three or so separate smaller boxes for easy transport. These components can be snap-fit together for easy assembly (and disassembly). The bed includes a bed frame, a power module or carriage and a bedding foundation. The foundation in turn includes a head portion and a body portion both of which are snap-fit securable in position to the power carriage. Pins releasably hold the roller assemblies of the power carriage to side rails of the frame for rolling moving of the carriage on the frame. A motor of the power carriage controllably moves the foundation head portion with respect to the frame and body portion. A drag link pivotally connects the head portion to the head rail of the frame. The drag link can be releasably connected at either end thereof or in the middle, snapping the two parts of the drag link together. The lateral rails, longitudinal rails and corner posts can be disassembled into four pieces with wedge-cup arrangements or rotatable camming locks.
