Abstract

A bed including a frame, an articulating deck on the frame having head, seat, and foot deck sections, and a mattress on the deck. The deck foot section and mattress foot portion have a first length when the foot section is in the up position and a second length shorter than said first length when the foot section is in the down position. A first driver varies the length of the deck foot section, and a second driver moves the foot section relative to said seat section between the generally horizontal up position and the generally vertically downwardly extending down position.
