Anything that helps me get in shape while sitting down is something that grabs my attention because unfortunately, I am sitting at my desk for at least 10 hours a day. The BalanceBall Chair is not your conventional office chair. Designed with help from the chiropractic expert Dr. Randy Weinzoff, the BalanceBall is a great way to strengthen your core muscles and improve your spinal alignment. The actual chair looks like a huge yoga ball on easy-glide casters with adjustable support for the lower back. It might not be the most stylin' chair but your back will definitely be thanking you!
