These mats are constructed of static dissipative high-twist nylon yarn that works to trap moisture and dirt. Classic Mats feature a traditional color styling. Choose from our wide variety of attractive colors to complement any color schemes. Classic Carpets feature a revolutionary coloring system that combines rich, dark background colors with bright, vibrant accent colors to produce a new standard in mat beauty. The multi-colored carpet looks like commercial carpeting and blends with many more decors than solid colors. Classic Carpets and Classic Mats can be washed together with your existing colors because these mats feature our Perma-Dye and StainStopper dyeing technologies.
