Our carpet floor chair mats are ergonomically designed to allow your chair caster to glide smoothly on carpet floors simultaneously protecting your carpet whilst reducing strain on the lower back and legs caused by receptive forced movement. They are available for high pile and low/medium pile carpets in a range of premium quality materials depending on your floor protection needs. All chair mats are free from BPA, phthalates and heavy metals such as tin, lead and cadmium and are indoor air quality certified, tested and approved by the Blue Angel European environmental jury. All carpet chair mats are equipped with super grip studs on the underside for effective grip on carpet floors and to prevent pile flattening. The slightly textured upper surface of the mat allows for effortless gliding with enough grip for maximum control.
