Our bodies were made to move. That''s why this anti-fatigue mat for standing desks and sit-stand workstations was ergonomically designed to inspire active standing. The non-flat standing desk mat combines cushioned comfort with a calculated topography to encourage varied movement and multiple stances, helping to reduce fatigue and enhance your comfort. Move and Stretch While You Work The contoured anti-fatigue mat is designed to encourage you to move freely while standing. Unlike a typical flat mat, this stand-up desk mat features a thick cushioned terrain with premium 3D features that make it easy to vary your movement while you work. Change Your Position Often Do calf stretches, core balancing or comforting foot massages using the 2.6" (66.8 mm) high textured massage bar.
