What are the main types of casters available on drafting chairs?

Drafting chair casters come in several types: (1) Hard-floor casters — soft rubber or polyurethane wheels designed for hardwood, tile, and laminate. (2) Carpet casters — harder nylon or plastic wheels that roll more easily on carpet. (3) Locking casters — include a brake that activates when weight is removed from the seat. (4) Heavy-duty casters — larger diameter wheels rated for heavier loads. (5) ESD casters — conductive or dissipative casters for electronics environments. Most chairs ship with carpet casters as default since many offices have carpet. If you have hard floors, request hard-floor casters or purchase them separately.
