ABSTRACT:
Disclosed is a pedestal base for furniture, such a chair. The pedestal base is comprised of a plurality of radially oriented leg members which converge on a central hub, the hub and all of the leg members being formed as an integral piece of molded plastic. The central hub has an upper portion which is adapted to receive a plastic bushing and a lower molded portion which in combination with the bushing holds a chair seat height adjustment mechanism, such as a pneumatic cylinder. The chair base is lightweight and less expensive to manufacture than prior metal and wood chair bases.
