What is a conference chair that works on both carpet and hard floors?

Dual-surface casters (also called 'all-surface' casters) are made with a soft outer wheel and a harder inner hub, rolling smoothly on both hard floors and carpet without damaging either surface. Specifying dual-surface casters eliminates the need to order different caster types for mixed-flooring conference environments.
