Here’s What Our Customers Have to Say

“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.”

Sherri, 38
