This Tilt Active has changed my life! In the evenings instead of lounging on the couch to watch the news I am comfortably tucked into the beautifully balanced active chair. The arms can be pushed down and then they spring back for a gentle exercise that feels great. Likewise the rocking action is barely perceptible as a strengthening of my core. Leaning back feels perfect and my upright posture is totally relaxed yet energizing.. Tai chi!
