Abstract: A collapsible chair adapted to be carried by a user wherein the chair comprises a seat which is pivotally attached to a support post which, in turn, is pivotally attached to a disk-shaped base such that the seat and base may be pivoted with respect to the post from an open, usable position to a collapsed position. The post includes a first threaded member rotatably received within a threaded bore of a second member such that the height of the seat may be adjusted with respect to the base as well as permit the user, while seated on the chair, to rotate with respect to the base. Locking pins are provided to facilitate the secure engagement of the seat and base, respectively, with the opposite ends of the support post during use and when the chair is in a collapsed position.
