If you work at a standing desk, you’ll love this

Ergonomic experts agree that “your best position is your next position.”  In other words, your body is meant to move.  And constant motion reduces fatigue as well as back and joint pain. Enter the Wurf Board, an inflatable platform for working at a standing desk.  As you stand on it, your body constantly adjusts, keeping you in a subtle state of constant motion.  Benefits include greater energy, focus and calorie burn.  While anti-fatigue mats make standing comfortable for an hour or so, the Wurf Board lets you stand easily for hours at a time.  Priced at $199-$269 and available in three sizes, it lets you work out while you work.
