the chair is quite comfortable. the predrilled holes are a little askew so the seat is off center a bit. the lumbar support is great however it moves too easily when I lean back. The adjustable arms are a benefit to me. I did not use the head rest attach
I had an imitation leather chair that I bought at Staples just over one year...glad I bought the extended warranty! I returned the chair and got this mesh back chair and I'm very pleased. I can sit more upright and it's much easier for me to spend time at the computer. Very pleased so far.
