This chair mat will protect your carpets from damage caused by office chair casters and dirty footwear. Polycarbonate is the best material for chair mats, as it won’t discolour, it won’t curl, bend or crack under normal use and it’s super-strong and long-lasting. For the office worker, it provides ergonomic benefits as your wheeled office chair will glide over the surface reducing fatigue and making it easy to move around. Polycarbonate is 100% recyclable, free from PVC and harmful chemicals. It lies flat immediately. Size: 75cm W x 120cm D
