How do I replace the casters on an office chair?

Office chair casters use a standard grip ring stem (usually 7/16" diameter) that presses into the base socket. To remove: grip the caster and pull firmly straight down — they often release with a sharp tug or may need a flat screwdriver to pry the grip ring. To install: press the new caster straight up into the socket until you hear a click. The entire process takes under 5 minutes for all five casters. When upgrading to PU rollerblade casters, verify stem diameter matches before ordering. FindOfficeFurniture.com can help you select chairs with upgrade-friendly caster systems — call 888-719-4960.
