1. An adjustable bed having a longitudinal and transverse axis comprising:
- an undercarriage;
two pivot support plates connected to said undercarriage;
a first and a second frame nested in said undercarriage;
pivot means connecting said first frame to said second frame and further to said support plates;
said pivot means defining a longitudinal axis;
a plurality of first and second frame support elements connected to said first frame and said second frame, respectively;
a first and second frame rotation means located at said transverse axis connected to one of said first frame support elements and one of said second frame support elements, respectively;
rotational control means connected to said first and second frame rotation means, respectively; and
said rotational control means comprising a limit switch mounted on one of said first and second frames, whereby an angle formed between said first and second frames is constrained to be at least ninety degrees and whereby said first and second frames are rotatable about said bed longitudinal axis relative to each other when said rotational control means is not actuated.

Abstract
An adjustable bed is provided with two frames which rotate about the longitudinal axis of the bed. The rotation is facilitated by a plurality of motors mounted on an undercarriage in which the two frames nest. The motors are controlled by a control unit, which when actuated causes raising or lowering of the nested frames relative to the undercarriage. One or both frames may be raised or lowered at the same time. A limit switch is placed on the frames which prevents the angle formed by the two frames from becoming less than ninety degrees.
