Abstract
A tilt mechanism for an office chair includes a spring tension control that incorporates a wedge arrangement including a moveable wedge component that is displaceable laterally by turning a control knob below the seat of the chair, to force fixed wedge components apart and increase the spring tension. Turning the knob in the opposite direction reduces spring tension.
