Excellent chair
Excellent chair that suited my expectations perfectly. Very comfortable, easy to assemble, and suitable for those with slight back pain, like me. I do not regret the investment.
However, I do have one criticism, but it's a bit my fault, I must admit. If you are in the upper limit in terms of height for this chair, the headrest will not serve you or worse, will cause you more problems than anything else. No big deal, really.
