preparing a chair base stack having a vertical stacking direction, by
inserting a co-engagement ring of a first chair base hub into an orifice of a second chair base hub, wherein a plurality of arms extends outward, in a direction transverse to the stacking direction, from each of the first chair base hub and the second chair base hub;
placing a first chair base stack on a transportation platform; and
placing a second chair base stack on the transportation platform such that the plurality of arms extending outward from the first chair base stack and the plurality of arms extending outward from the second chair base stack are laterally interspersed.
