An adjustable articulated bed which may be disassembled for easy shipping in a small container and which is constructed from a minimum number of components is shown. The bed includes a frame, power drive module which nests within the frame and an articulated mattress. In one embodiment, the power drive module includes all necessary moving parts to form the articulated bed so that any frame may be used. In another embodiment, the power module includes all moving parts but for a pivotal linkage which mounts between the lower leg section of the articulated mattress and the frame. In either embodiment, the power module includes a pair of central support members which are separated by a lateral support. The lateral support is provided with a square cross section that aligns the central support members and drive motors mounted thereon. The pivot points are arranged in the two planes formed by the central support members for increased strength.
