Reactive and supportive, our chairs reduce pain and the risk of developing it. Our Sit in Motion® technology does the work for you, allowing the seat saddle to respond ergonomically to every movement so that you always maintain ideal posture.

FOLLOW DOCTOR’S ORDERS

Designed by LA’s leading chiropractor, our chairs have earned the support of the wellness community. Watch world-renowned Dr. Travis Stork explain why he believes the all33 BackStrong chair is a must-have for anyone who sits throughout the day.

INVEST IN YOUR HEALTH

The BackStrong C1 is the only chair in the world that allows natural movement of the pelvis and back while you sit. This allows for healthy blood flow all day long and increased flexibility. Plus, the foldaway arms allow you to sit closer and reduce strain on your eyes.

“This is the best chair on the market. Allows your spine to move and flow with your movements. It’s awesome.”

Pat, 62

“I have had back and hip pain for awhile, and it’s noticeably gone now. All of that disappeared the first time I sat down, raised the seat, adjusted the tension and then played with the bucket element. By the time I was done, I stood up without any pain. No more lower back pain, body stiffness and legs that fall asleep.”

Chris, 53

“All of a sudden I was working at home. I was in ergonomic agony until I received my all33 chair. Now my back is supported! No more heating pad for me. Thanks all33!”

Gene, 49

“Because of the engineering it always forces me to sit up straight.”
