ABSTRACT OF THE DISCLOSURE The chair of the present invention includes a power- assisted linear actuation drive mechanism having a modified nut or "cam guide" which is linearly moveable upon rotation of the power screw for selectively actuating the lift and tilt linkage mechanism for causing forward lifting and tilting movement of the chair when the motor is operated in a first direction. Rotation of the screw shaft in a second opposite direction acts to lower the chair to the normal seating position. Continued rotation in the second direction causes sequential operative extension of the leg rest assembly followed by angular reclining movement of the chair. This sequential operation of the leg rest assembly and the reclining linkage are independent and may be easily disabled to selectively eliminate either of the features.
