ABSTRACT:
A portable foldable relaxing chair orthopedically designed to reduce stress in either the supine or prone position capable of allowing one to assume an orthopedic posture of weightlessness at about 127.degree. in the supine position and significantly reducing stress to the lower back at approximately 185.degree. in the prone position while supporting the sides of the face and neck with a head piece made of two foam supports. A head and foot rest is provided which are attached through pivots capable of lengthening and shortening to suit the user's height and of angular positioning for proper support and comfort. The chair comprises a back and seat panel of any suitable fabric which is replaceable inserted into side frames attached by hinges. Arm rests are attached by fixed pivots to the back frames which pivots support front legs hinged to rear legs which are in turn attached by seat adjusting guide assembly angles along the outer seat frames. Said assemblies allow for slidably raising and lowering the legs by a knob and clamp arrangement while remaining seated.
