This 3″ dual wheel carpet caster is a direct replacement for worn out or broken casters on Herman Miller® Aeron® and Mirra® office chairs.  This caster is made in the USA from quality materials in accordance with Herman Miller@ specifications.  Our casters are constructed with durable nylon wheels and yoke and have a steel B type (7/16″x 7/8″) stem.

Choose a hard wheel caster for use on carpeting to provide smooth rolling and a soft wheel caster for use on chair mats and other hard floor surfaces including wood, tile and linoleum to prevent damage.
