Sitting all day long to do work or read is not a smart idea. Studies have shown that it could come back to haunt you and cause major health issues. Many of us are also guilty of not maintaining proper posture while working. These 3 chairs can help you sit in a more active fashion to keep your back healthy:
Gaiam Balance Ball Chairs: helps build a healthier back and align your spine. It also could relieve pain.
Wobble Stool: can serve as a bar stool or active sitting chair. It has rounded edges to keep you comfortable. You can burn calories by using this chair.
Kore Office Ergonomic Rocker Wobble Chair: allows you to move and flex without leaving your seat. Lets you exercise legs, back, and abdominal muscles.
I personally prefer using a standing desk while working. But these active chairs could also help you stay healthy while working.
