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.

1. A method for stacking chair bases, the method comprising: positioning a first chair base adjacent a second chair base, wherein the first chair base and the second chair base are separate chair bases to be stacked upon one another, and wherein each chair base comprises: a hub; anda plurality of legs extending radially from the hub;the hub, comprising: a top end with a top planar surface and an inner diameter; anda bottom end with a bottom planar surface and an inner diameter, and wherein the bottom end is configured to be disposable within at least a part of the inner diameter of the top end of a separate chair base;the bottom end further comprising: an annular ridge disposed on the bottom planar surface; andan annular ring extending axially and downwardly away from the annular ridge, the annular ring having an outer diameter less than the inner diameter of the top end; andengaging the bottom end of a first chair base hub with the top end of a second chair base hub in order to couple the first chair base to the second chair base, such that the annular ring of the bottom end of the first chair base hub is disposed within at least a part of the inner diameter of the top end of the second chair base hub, the outer diameter of the first chair base ring engaging the inner diameter of the top end of the second chair base to prevent lateral displacement of the first chair base relative to the second chair base. 2. The method of claim 1, wherein the annular ridge and the annular ring of each chair base hub are formed integrally with the chair base hub. 3. The method of claim 2, wherein the annular ring further comprises a rotation engagement feature configured to substantially prevent any engaged chair base hubs from rotating relative to one another. 4. The method of claim 3, wherein the rotation engagement feature comprises a protrusion, and wherein the top end of each chair base hub further comprises a recess configured to engage the protrusion in a separate chair base hub to substantially prevent any engaged chair base hubs from rotating relative to one another. 5. The method of claim 4, wherein the method further comprises: rotating the first chair base hub relative to the second chair base hub so that the recess of the first chair base hub is radially aligned with the protrusion of the second chair base hub; andengaging the recess of the first chair base hub with the protrusion of the second chair base hub. 6. The method of claim 1, wherein the annular ridge and the annular ring are formed on a separate stacking ring disposed between the first and second chair bases. 7. The method of claim 1, wherein the method further comprises transporting the engaged first chair base and second chair base on a pallet. 8. The method of claim 1, wherein the method further comprises preventing the first chair base hub and the second chair base hub from substantially rotating with respect to each other by wrapping the legs of the first chair base and the legs of the second chair base in plastic. 9. A chair base system for stacking, the chair base system comprising: a first chair base, wherein the first chair base comprises: a hub; anda plurality of legs extending radially from the hub;the hub, comprising: a top end with a top surface and an inner diameter; anda bottom end with a bottom surface and an inner diameter;the bottom end further comprising: an annular transition portion disposed on the bottom surface; andan annular ring coupled to the annular transition portion, the annular ring having an outer diameter less than the inner diameter of the bottom end of the hub, anda second chair base, wherein the second chair base comprises: a hub; anda plurality of legs extending radially from the hub;the hub, comprising: a top end with a top surface and an inner diameter; anda bottom end with a bottom surface and an inner diameter;the bottom end further comprising: an annular transition portion disposed on the bottom surface; andan annular ring coupled to the annular transition portion, the annular ring having an outer diameter less than the inner diameter of the bottom end of the hub,wherein the bottom end of the first chair base hub is configured to engage with the top end of the second chair base hub in order to couple the first chair base to the second chair base, such that the annular ring of the bottom end of the first chair base hub is disposed within at least a part of the inner diameter of the top end of the second chair base hub, the outer diameter of the first chair base ring engaging the inner diameter of the top end of the second chair base to prevent lateral displacement of the first chair base relative to the second chair base. 10. The chair base system of claim 9, wherein the annular transition portion and the annular ring of each chair base hub are formed integrally with the chair base hub. 11. The chair base system of claim 9, wherein the annular transition portion and the annular ring are formed on a separate stacking ring disposed between the first and second chair bases. 12. The chair base system of claim 9, wherein the engaged first chair base and second chair base are transported on a pallet. 13. The chair base system of claim 9, wherein the bottom surface of each chair base hub is flush with a location in which the plurality of legs are attached to the bottom end of the chair base hub. 14. The chair base system of claim 9, wherein the bottom surface of each chair base hub extends below a location in which the plurality of legs are attached to the chair base hub. 15. A set of stacking chair bases comprising: a first chair base;a second chair base adjacent to the first chair base, wherein the first chair base and the second chair base are separate chair bases to be stacked upon one another, and wherein each chair base comprises: a hub; anda plurality of legs extending radially from the hub;the hub, comprising: a top end with a top planar surface and an inner diameter; anda bottom end with a bottom planar surface and an inner diameter, and wherein the bottom end is configured to be disposable within at least a part of the inner diameter of the top end of a separate chair base;the bottom end further comprising: an annular ridge disposed on the bottom planar surface; andan annular ring extending axially and downwardly away from the annular ridge, the annular ring having an outer diameter less than the inner diameter of the top end; andwherein the bottom end of a first chair base hub is engaged with the top end of a second chair base hub in order to couple the first chair base to the second chair base, such that the annular ring of the bottom end of the first chair base hub is disposed within at least a part of the inner diameter of the top end of the second chair base hub, the outer diameter of the first chair base ring engaging the inner diameter of the top end of the second chair base to prevent lateral displacement of the first chair base relative to the second chair base. 16.
