People spend hours every day sitting on chairs; however, the human skeletal frame is not designed for chairs. Even ergonomic chairs, intended to hold the body upright, only do so effectively for a short period of time. After that, the postural muscles tire and the body slumps and slouches as the spine twists out of alignment. Ultimately, postural muscles weaken, leading to back pain and potentially putting you at risk for a back injury.

By introducing a dynamic element to the sitting experience, the Evolution Chair™ keeps your muscles active while you are seated. This not only holds you in the correct position for your spine but also allows you to build your core strength while you sit. This new concept in sitting can contribute a great deal to your overall well-being, especially for those who sit for long periods at a time.

Who Will Benefit?
Sitting on the Evolution Chair™ builds the multifidus, rotatories and transverse abdominus muscles that lay deep within the trunk —small spinal stabilizers that are essential for conditioning the body's core


The Evolution Chair™ is suitable for anyone who sits for extended periods of time. Good posture and core strength are the best insurance against back injury.

The Evolution Chair™ is a unique and comfortable alternative to an ordinary chair. Sitting on the Evolution Chair™ takes pressure off the spine, releases muscle tension, corrects posture, improves balance and strengthens the torso.

It is suitable for all ages. Anyone who sits at a desk for hours; students, office workers, computer professionals, health care professionals, individuals with back and neck problems and even children who need to be encouraged to assume a more correct posture. In fact more and more dentists are using the Evolution Chair™ to alleviate chronic lower back pain which bears testimony to the therapeutic benefit of the Evolution Chair™.

How it works
The Evolution Chair™ 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.

Testimonials
"While many people spend time in the gym doing strengthening exercises, most are not mindful of the tremendous long-term health benefits associated with active sitting and the accompanying improvement in posture and core strength. I’m convinced that the Evolution Chair™ is a good seating choice and I will recommend it to my patients."
