Black poly plastic stool without arms. Almost every BodyBilt chair can be made into a clean room chair, or even an ESD. Our clean room and ESD chair still have all the ergonomic benefits of a BodyBilt Chair. Depending on the fabric used, we can build a chair to meet the strict requirements for cleanroom Class 1, 10, and 100 ESDSTM 12.1-1997 standards. We have also tested certain fabrics for use in dental and medical environments, to where caustic cleaners such as bier can be used daily to clean the chairs. For ESD environments, we start with electric dissipating fabric, and then ground the entire chair through to casters (wheels). We use a resistor in cylinder and also use special ESD caster. In fact, on the ESD chair two 2.0 megohm, 2 watt resistor are used to provide efficient static dissipation with the necessary margin of safety. When we are done, each ESD chair is tested and approved for use in ESD environments.
