The anti-fatigue mat is manufactured with premium, high-density molded foam. It’s a solid, 1 piece design without pleather or other cheap materials to hide defects. Their industrial design engineers calculated the correct density and materials to provide cushioned, anti-fatigue properties that you can feel as soon as you step on the mat. The size, dimensions, and properties of the mat are based on human factor principles - it’s small and light enough to be easily moved but large enough to give you room to move. It fits perfectly in most cubes and offices and it’s the ultimate compliment to any standing desk!
