The patented Active Standing Mat has a contoured surface that's specifically engineered to encourage movement while standing. With space for static standing, the 1" thick floor, which is much thicker than most "cheap" mats, provides excellent cushioning comfort that you can feel. Sloped sidewalls allow you to elevate one or both feet, stretch your calves and stand comfortably with a wider stance. The center massage ball massages and stretches your feet and makes it easy to slide the Active Standing Mat out of the way when you don't need it. The Active Standing Mat is manufactured with a premium, high-density molded foam. It's a solid, 1-piece design without pleather or other cheap materials to hide defects. The industrial design engineers calculated the correct density and materials to provide cushioned, anti-fatigue properties that you can actually feel as soon as you step on the mat. 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. The Active Standing mat fits perfectly in most cubes and offices and it's the ultimate compliment to any Standing Desk! Perfect for Any Standing Desk: Lightweight, durable, and ideal for home offices or professional workspaces. Ergonomic Anti-Fatigue Support: Cushioned foam reduces pressure on knees, hips, and lower back. Boosts Energy & Circulation: Helps keep your legs active during long standing sessions. Ultra-Comfortable Design: Gives your feet multiple ways to move, flex, and massage throughout the workday. Stimulates Movement: Raised edges and terrain zones encourage natural stretching to reduce stiffness and fatigue. | Active Standing Desk Mat 20x34" Non Flat Contoured Anti-Fatigue Comfort Cushion Floor Mat for Stand Up Office Desks
