The Revolutionmat Chairmat provides high-quality floor protection and ergonomic performance combined with excellent value. Its strong surface protects your flooring from damage caused by office chair casters, general wear, scuffs and spills. Rigid top surface with low-roll resistance allows your chair to glide easily. Durable design will not crack, chip, break or shatter under normal use and correct application. Polypropylene construction is free of phthalates, tin, lead, cadmium and BPA for peace of mind when used around children or pets. The natural, translucent finish and embossed top surface are great for obscuring worn and damaged flooring. Chairmat is compatible with under floor heating systems. Anti-slip backing is designed for hard floors and very low-pile carpets.
