An armrest assembly for attachment to a chair includes a base plate. The base plate can be secured, in a chair of the type including a (i) seat bottom cushion on which a person can sit, (ii) a pedestal assembly supporting the seat bottom cushion, and (iii) a plurality of fasteners securing the pedestal assembly to the underside of the seat bottom cushion, between the seat bottom cushion and the pedestal. The base plate has a plurality of fastener openings equal in number to the number of fasteners in the chair to which the armrest assembly is to be attached. The fastener openings are arranged in the same pattern as the fasteners in the chair to which the armrest assembly is to be attached. The base plate can have at least two sets of fastener openings arranged in different patterns, whereby the base plate can selectively be secured intermediate the pedestal assembly and the seat bottom cushion of at least two different chairs having different fastener patterns. The armrest slides relative to the armrest support, allowing the armrest to be moved laterally, rather than only arcuately, compensating for the arcuate motion provided by a pivot joint. The armrest assembly is responsive to downward force on the armrest from the person\s arm to restrict movement of the armrest relative to said base. Pressure (i.e., weight of the arm or gravity) locks the armrest into a given position, providing a more stable working platform.

An armrest assembly for use with a chair having a seat with a lower side and an upper side which is engaged by a person sitting on the seat, said armrest assembly comprising an arm disposed beneath the seat and having a first end portion pivotally connected with the lower side of the seat at a location spaced from edge portions of the seat by a distance which is at least substantially as great as the length of said arm, said arm being pivotal about a first axis which extends transversely to a central axis of said arm to move said arm along the lower side of the seat, said arm having a second end portion which is disposed adjacent to one of the edge portions of the seat, a support member connected with and extending upward from said second end portion of said arm, an armrest connected with said support member, said support member being pivotal relative to said arm about a second axis which extends transversely to the central axis of said arm to enable said armrest to be pivoted about the first and second axes, and a slide assembly connected with said armrest and said support member, said slide assembly including a flat side surface, said armrest being movable relative to said support member in any direction parallel to said flat side surface.
