Transforming Technologies ComfortDome ESD Anti-Fatigue mat provides unparalleled comfort in areas where static control is a concern. Evenly spaced ComfortDomes on the conductive surface of the mat provides superior anti-fatigue relief because ComfortDomes get softer as compressed, not harder like products made with foam. ComfortDomes recover/rebound more rapidly than most foam resulting in an energizing responsiveness not found in other mats. Size: 3’x4′. Point to Point Resistance: 10e3 – 10e5. Meets or exceeds requirements of ANSI ESD-S20.20 and the recommendations of ESD STM7.1.
