ABSTRACT:
A multiple position, reclining and stretching chair includes a base structure having side walls with corral openings into which the ends of an axle extend. The axle is rotatably secured to a lumbar platform that is a part of a multi-panel body support platform assembly. The body support platform assembly is positioned above an arcuate, adjustable, lockable, contact support structure that pivots forward and rearward about one or more pivot members either or both of which that may be substantially attached to the base structure. The contact support structure may also comprise two sets of independently acting contact support members that allow the front roller to move independently of the rear roller. Also disclosed is an embodiment wherein the arcuate roller assembly rocks back and forth about the surface of a horizontal cross support member of the base structure.
