A body weight chair control in which the chair back and chair seat may be adjusted independently of each other. The chair occupant's body weight is the source of energy in moving both the back and seat. The chair control includes a front link and a rear link, each pivotally mounted on a base link. An intermediate link is pivotally mounted on the rear link, and a seat link is mounted on and between the intermediate link and the front link. A releasable locking mechanism is provided to lock two non-connected links in fixed relation, whereby all five links are locked in fixed relation.
