Our electro-static dissipating (ESD) seating neutralizes static generating processes by providing proper grounding, conductive, and dissipative static control materials. The result is a safer work environment and the reduction or elimination of static discharges that can damage sensitive equipment. Meets stringent class 100 cleanroom and ESD standards. We’ve seen other chairs fall apart almost out of the box. Bad welds, cheap casters, poor cylinders – they’ll do your chair in quickly. That’s why we place so much importance on build quality. This model employs reinforced steel to make sure you can trust your stool for many years to come. We promise to offer the very best quality and craftsmanship.
