How it Works


The Evolution Chair&trade is a high quality burst-resistant ball contained within a moving base. Simply by sitting on the ball and adjusting your body to the bounce, sway and tilt of the ball, deep core muscles are engaged. These constant small adjustments build the endurance and strength of the postural muscles which facilitate optimal posture. Active sitting is guaranteed to complement your regular exercise program.

The Evolution Chair is height adjustable, which is a key factor in proper ergonomics, without the height adjustments users would not be able to sit in the correct ergonomic position. In fact, the prevalence of repetitive strain injury affecting seated workers is often due to poor ergonomics. The Evolution Chair provides the necessary adjustments to attain correct posture and limit the incidence of pain. Height inserts are included with your Evolution Chair to adjust the height of the rolling base; in addition, the heavy-duty anti-burst ball is made of a very flexible material to allow different levels of inflation.
