This is a great chair. When I sit straight up at the desk typing I can actually feel the lumbar support. The headrest is great for when I want to lay back and relax for a minute. The chair rocks back really smoothly and easily too.
I bought this chair as I am now working from home and I am able to sit comfortably for eight plus hours and still feel comfortable. The reason I did not give five stars is the headrest could be a littler higher as I am 5’7 1/2”.
