High-density, closed-cell nitrile rubber cushion provides excellent anti-fatigue qualities to reduce the pain and fatigue associated with standing for long periods of time. Beveled edges provide a safe transition from floor to mat and will not crack or curl. Nitrile-blended cushion is molded, not glued, to the nitrile rubber surface so it will not separate. Certified high-traction by the National Floor Safety Institute (NFSI).
