To adjust the chair for different occupant weight the lever is respositioned automatically by first releasing the normal coupling between seat, lever, and spring; and second, the lever is positioned in accordance with occupant weight. Then the coupling between seat, lever, and spring is reestablished for normal operation. In one embodiment the lever is moved relative to its pivot to adjust for weight variations.
