ABSTRACT:
A chair having height-adjustable arm assemblies mounted adjacent opposite sides of the seat. Each arm assembly includes a horizontally elongated armrest which adjacent one end is connected to an upper end of a support column. The support column is axially slidably supported within an elongate support tube which projects downwardly adjacent a side of the chair seat. The support column and support tube have a cooperating linear anti-friction bearing arrangement therebetween, the latter incorporating a resilient support track to eliminate circumferential clearance. A latch mechanism includes a movable latch member carried on the column and cooperating with a plurality of latch-receiving slots formed in the support tube. The latch member is activated by a push rod which projects upwardly through the support column, and at its upper end is activated by an actuating lever which is pivoted on and projects lengthwise of the armrest and terminates in an actuating button disposed under the front end of the armrest.
