Caster: Multi-Surface Caster with Quiet Roll - Designed to be used on hard surfaces such as wood, ceramic tile, vinyl tile, or carpeted floors, this 2.5-inch diameter caster features a subtle braking feature that prevents chairs from rolling away when they are not occupied. Casters are made of durable black nylon, with a soft tread that gives the chair better traction and reduces noise on hard surfaces. Quiet Roll Technology controls vibration of casters within the base when the chair rolls.
