Move from one desk space to another with smooth ease thanks to the MatTEK Anchormat executive chair mat. Designed for use on medium-pile carpets with a thickness of 6-12mm including the underlay. Constructed from durable twice extruded PVC, the Anchormat features rounded base grippers that keep that mat securely fixed to the carpet for a safe glide. By using a chair mat underneath your castor wheeled office chair, you are helping reduce the wear on both the castors fighting through carpet and the carpet itself from overwear.
