What size casters do executive chairs have?

Standard executive chairs come with 2"–2.5" diameter casters. Larger casters (3") roll more easily over carpet and provide better floor clearance, and are common on heavy-duty or big and tall models. The caster stem is almost universally 7/16" diameter x 7/8" length (the industry standard grip ring stem), making them interchangeable across most office chairs. Hard-floor casters and carpet casters are sold as matched sets. OfficeFurniture2go.com can confirm caster size and type for any model — call 1-800-460-0858.
