Electrostatic discharge (ESD) and cleanroom chairs provide total body support for prolonged sitting while helping protect workers from static discharge and environmental pollutants. They are commonly used in the semiconductor, bioscience, pharmaceutical, computer, and medical equipment industries. Also called task chairs, they have pneumatic seats that adjust to an optimal working height. ESD chairs are made of nonconductive materials, static-free fabric, and static-free slides or casters. Cleanroom chairs have durable seats and backs that resist punctures and damage from water, oils, and most chemicals.
