On the occasion of the use

Anti-static chairs discharge the electro-static charge of the human body by a safe speed, through the dissipative resistance, though static charge is generated by friction between clothes or body and back or seat, or by contact between human body and chair if it is located on the conductive floor. If floor is isolated from ground, it does not work. Please use on the conductive floor.
