Stand comfortably for longer periods with this ergonomic, not-flat anti-fatigue mat. The contoured terrain mat is engineered based on human factor principles to let you move in natural comfort. Prop a foot up, take a wide stance, stretch your calves, massage your insoles, or stand still in cushioned comfort with this anti-fatigue floor mat. It’s like a jungle gym for your feet! The patented Active Standing Mat has a contoured surface that’s specifically engineered to encourage movement while standing. A 1” thick floor provides excellent cushioning comfort that you can feel when standing still. Sloped sidewalls allow you to elevate one or both feet, stretch your calves and stand comfortably with a wider stance. The center massage ball lights up those neurons as it soothes and stretches your feet.
