Many of us are looking for new ways to get more active at work. Getting a decent sit-stand desk can help. The ErgoErgo Active Sitting Stool is also worth a look. It lets you gently move your body to engage your core and relieve your back pain.
ErgoErgo can be used as a gaming or office chair. This wobble seat is made of recyclable technopolymer and has a flat base for stability. It can handle up to 225lbs of weight. The ExtraErgo has more sitting room and stability for larger, taller adults. A smaller version is available for kids.
