Abstract: The embodiments relate to a geometric under structure, central and outer hub for a GFN plastic chair base. The geometric shape and dimensions are critical components to the overall strength of the chair base hub and arms when either vertical or rotational forces are applied at the central hub. The central hub is of sufficient thickness to maintain dimensional stability when the forces are applied. The overall geometry and material composition enable the hub area to be constructed with minimal plastic wall thickness while optimizing the physical strength of the article and facilitating high production rate.

Abstract: A stacking ring for a chair base may be disposable between a first and second chair base such that the stacking ring generally prevents lateral movement of the first chair base relative to the second chair base. The stacking ring may be integrally formed to the chair base, or separate and disposable between at least two chair bases. The stacking ring may substantially prevent rotation of a first chair base relative to a second chair base.
