Caster Guide
How do I choose replacement caster parts for my desk or office chair?
Casters (chair wheels) usually come in sets of 5 to fit your base. All casters should be replaced at the same time for safe, smooth rolling. Determine correct stem diameter by removing a caster from the leg of your chair base. As long as your existing casters have 7/16” (11mm) diameter stem, you’ll be able to use our casters as replacements. Things to keep in mind when shopping for a wheel are the color, wheel diameters, stem diameter, and the stem length. We've placed them below in a charts so you can quickly identify your needs.
Are you still having trouble deciding on a chair base? If you know the flooring surface where you will be using the chair you can help decide in the caster details. Often the description will indicate where the wheels are recommended for best use.
