Abstract: A foot and/or leg support device for a chair, the chair including a central post having a base, a seat supported by the central post, and a plurality of support legs which branch from the base of the central post. In an example, the support device includes: a connector for attachment to the central post of the chair, wherein the connector comprises a circular interior having a radius of curvature substantially equal to a radius of the central post of the chair; a cantilever arm which extends from the connector; a pivot which connects the cantilever arm to the connector, the pivot being configured for vertical pivoting; and a support frame located at a distal end of the cantilever arm for supporting a foot and/or leg of a user.

Abstract: A foot and/or leg support device for a chair. The chair includes a central post having a base, a seat supported by the central post and having a front seat edge, and a plurality of support legs which branch from the base of the central post. The support device includes a clamp for attachment to the central post of the chair, mountable to different diameters of the central post, a cantilever arm which extends from the clamp, and a support frame located at a distal end of the cantilever arm for supporting a foot and/or leg of a user, the cantilever arm being a length wherein at least part of the support frame extends past a vertical plane of the front seat edge of the chair. In an example, the support frame can be installed onto the central post without disassembling the chair.
