ABSTRACT:
A chair includes a tubular arm support, an armrest, a lateral adjustment mechanism and a vertical height adjustment mechanism. The lateral adjustment mechanism includes a plurality of nested slides. One slide is connected to the vertical height adjustment mechanism. An uppermost slide supports the arm rest. The slides are adjustable laterally with respect to each other to position the armrest with respect to the chair. The vertical height adjustment mechanism includes a tubular liner insertable into the arm support. The liner defines a bore and a plurality of vertically spaced notches or grooves. A latch tube telescopes within the bore of the liner. An upper end of the latch tube is connected to the lateral adjustment mechanism. The latch is pivotally positioned within the latch tube. The latch includes a latch end movable into and out of engagement with the notches. An actuator engages the latch to move it between locked and unlocked positions.
