A control mechanism for a chair that enables a plurality of adjustments to be made to the chair by a seated occupant in a cost effective and reliable manner is described. The control mechanism includes a plurality of motor-gear groups and at least one control switch. The control switch is coupled to each motor-gear group, a rechargeable battery, and to a limit switch that limits an amount of height adjustment of the chair seat with respect to the chair base. Each motor-gear group is coupled to a drive shaft. As a result, a seated occupant may engage the control switch to selectively electrically raise or lower the chair seat relative to the chair base, tilt the chair seat relative to the control mechanism, tilt the chair back relative to the chair seat, adjust the height of the chair seat relative to the control mechanism, and adjust the chair seat depth relative to the chair back.
