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.
