Trent anti-slip mats underlay prevent mats, rugs and runners from slipping and puckering on textile flooring such as carpets. If your rug slides on your floor it can develop ridges which will weaken the backing and cause extensive damage which can prevent the rug from lying completely flat, not to mention the safety issues if you trip over it! A special coating is used to provide the maximum support without leaving any sticky residues on your floor, unlike spray products.
