What is the working principle of anti-static chair?

When a person sits on an anti-static chair, the static electricity generated by the human body will be conducted through the conductive material on the of the chair. If the chair has a grounding device (such as a grounding chain or conductive casters), the static electricity will flow into the ground along these. This is like building a safe "evacuation passage" for static electricity, preventing it from accumulating between the human body and the surrounding environment, and thus avoiding occurrence of static discharge. Many anti-static chairs on the market are essentially the same as ordinary chairs. To buy one that meets the quality standards, it is best to one made by a reputable manufacturer with relevant certification qualifications.
