TITLE OF THE INVENTION: ECCENTRICALLY ROTATABLE CHAIR ABSTRACT OF THE DISCLOSURE: A chair for business or home use comprises a rotatable seat supported on a single leg at the bottom of which is a ball bearing caster. The leg is connected by a telescopically exten- sible arm to a pivot post which projects upwardly from the center of a circular base plate on which the ball bearing caster is adapted to roll as the chair swings around the pivot post. The chair may also have a back rest which is mounted for universal movement on a back support which extends rearwardly from an upper portion of the chair leg and then upwardly. The ball bearing caster comprises a larger ball retained in a socket and resting on a circle of smaller bearing balls so that the larger ball can rotate freely in all directions. Alternatively the ball bearing caster comprises a plurality of balls in a retainer.
