While it may appear the casters are “shredding”, in actuality, dirt has built up on the surface of the caster over time and is now flaking off. Most often this situation is the result of using a “hard” caster on a hard surface (wood floor, tile, chair mat).
•    First, thoroughly clean the flooring area where the chair will be used and the casters to remove any built up dirt. Periodically clean the work area to remove the surface dirt and eliminate the build up.
•    Consider switching to a “soft” caster if the chair you currently have has hard casters. Soft casters are available for purchase from The HON Company. To ensure you are ordering the correct caster for your chair, please locate the serial number on the sticker located on the underside of the seat and contact the original purchasing dealer..
