All33 Backstrong Chair Review. Our final recommendation is that the all33 backstrong chair is a product that’s worth trying if you’ve got chronic low back pain and spend a lot of time sitting. According to all33, the optimal height range for this backstrong chair is 4′ 11″ to 6′ 1″ (151 to 186 cm).
Not only was the chair easy to unbox, i had it completely assembled in a manner of minutes. All33 is an amazing solution to improving your posture and health. I purchased this chair, but found it to be uncomfortable.
