When two worlds collide

Chiropractor Dr. Dennis Colonello and Industrial Designer Jim Grove spent years researching, prototyping and testing the first true innovation in chair technology in the past 3,000 years. Tired of seeing patients return with painful, chronic conditions caused by their office chairs, Dr. Colonello approached Jim Grove with the idea for a chair that prevented health issues before they developed. Together, they spent five years designing and manufacturing the BackStrong for a better, healthier future for all.

Boost productivity. Increase energy levels and better your blood flow. Improve back and core strength. These are just a few key benefits of active sitting the all33 BackStrong C1 Chair provides. While traditional chairs lock the pelvis in place, resulting in the host of health problems that comes with sitting still, all33’s patented Sit In Motion® Technology allows for natural movement so your spine can stack in the same way it does when you walk.  


Whether you sit for hours or minutes, the chair moves with you for an easy, comfortable and painless experience every time.
