Plenty of people now use standing desks at work to stay active and burn calories. With anti-fatigue mats, you can get an even more comfortable experience. The ActiveMat Groove is not your average work mat though. It has a center groove that holds a ball, which you can roll and play with to relieve stress and stimulate blood circulation.
The ActiveMat Groove supports feet, knees, hips, and back. Soft, medium and firm roller balls are included. This set has a footprint of 35.5″(w) x 24.0″(d).
