Product Description
The Zenathletics ZenZu Ball Chair takes pressure off of the spine, releases muscle tension, corrects posture, improves balance and strengthens the torso.The main problem with sitting in a conventional chair is that it does not encourage movement. Furthermore, the human skeletal frame is not designed for chairs. We may be able to sit "properly" for 10 - 12 minutes, but after that our muscles become tired and we fall into bad posture, most often using a backrest. Sitting on the ZenZuTM ball, your body is constantly making smalladjustments with the postural muscles, abdominals, gluteals and leg muscles. It is "active sitting" rather than the slumping and poor posture we develop even in ergonomic desk chairs.
