ABSTRACT:
An adjustable armrest attachment for a secretarial chair has left and right elbow rests with depending posts independently selectively positionable within vertical channels formed in turned back outer ends of respective left and right, oppositely laterally extending bracket members. Superposed inner ends of the bracket members are attached to the chair by fasteners which pass through lateral slots to permit opposite lateral movement of the members to selectively vary the lateral spacing of the rests. In one embodiment the inner ends are attached by a bracket plate to a column that elevates a backrest at the rear of a seat. In another embodiment, the inner ends are attached by a knurled, manually manipulable knob to the underside of the seat. The rests are located to give the reduce antigravity stresses when the chair is pulled under a desk or table for raised hand operations, like typing.
