Designed for all hard floor surfaces and particularly effective on highly polished floors, the Cleartex Ultimat Anti-Slip Rectangular chairmat features a low-tack backing to prevent the mat from sliding across the floor without marking the surface. This water-based, nontoxic coating keeps hardwood, tile, laminate and linoleum floors from being gouged, scuffed and experiencing excessive wear and tear. Totally clear design lets the beauty of your floor show through. Extremely durable, polycarbonate material won't cup, curl, crack, discolor or smell. Mat is free of phthalates, PVC, tin, lead and cadmium.
