Choosing office chair caster sets

Load: divide the loaded weight by three for a four-caster cart [S2]. Divide each set rating by the number of casters in the set to get the per-caster rating.
Stem: the most common stem on office chair caster sets is 7/16 x 7/8 in; check the old stem with calipers before ordering.
Floor: on office chair caster sets, polyurethane and rubber are kinder to tile and finished floors; nylon rolls easier under heavy loads on smooth concrete.
Rig: swivel office chair caster sets are listed, with side lock brake options.
