Abstract: A generally upright open framework, having patient forearm and hand supports and having a horizontal seat intermediate its height, is supported by a platform mounted on a vertically adjustable pedestal base. Back and torso support members, telescopically received by sockets on the platform, form a back rest when the frame is in cast chair position. Base supported universal joint connected foot rests support the feet and legs of a seated patient. The back and torso members are movable to a second position on the platform to form a torso and head support for a supine patient. Telescopic tube extensions are supported by other sockets on the platform and include universal joint connected feet enveloping members for supporting the feet and legs of a supine patient when the frame is in spica table position.
