ABSTRACT:
A chair intended for therapeutic use has integral seat, back and leg support zones mounted for rocking movement between limiting positions defined by the surface on which the chair stands. The back support zone is formed with a hump positioned to project the lumbar region of the user upwardly relatively to the rest of his spinal column. The back zone terminates in a head portion that is adapted to position the head of the user correspondingly to the pattern of his projected lumbar position. The distance from the seat zone center of the seat portion to the end of the head portion is approximately 900 mm and to the center of the lumbar support zone approximately 600 mm. The leg and back zones are inclined to each other at about 150.degree..
