Thick mat dramatically reduces pressure on your feet, knees, lower back and insulates your feet from a cold or slick floor. Perfect for anywhere you stand for extended periods of time such as your office, workbench, or kitchen. Top thermo-fiber layer looks great and cleans off easily with a damp cloth/sponge, or gentle sweeping with a broom.
