ABSTRACT:
Optimal body weight distribution and excellent sacro-lumbar support is provided by a chair which changes configuration automatically to support the body in any sitting posture. The chair seat is mounted on a pair of laterally spaced-apart, elongated, substantially parallel seat supports disposed lengthwise of the chair, and the seat has sleeves that are received telescopically on the seat supports for sliding movement such that the seat slides forward and backward, relative to the chair back. The back tilts independently of the seat to conform to the sitting posture of a person sitting in the chair.
