The thickest vinyl chair mat available at .250". This mat features a textured top surface that is scuff resistant. The exclusive AnchorBar cleat system makes chair mats less dangerous to handle. Using a series of staggered perpendicular bars, the cleat system "anchors" the mat as securely as traditional cleats yet are gentle on the carpet and fingers. This premium extra thick mat is best suited for Home & Executive offices with thick carpet & padding.
