nice comfortable and has enough adjustment.. my only problems are with the lumbar support that will not remain in place (it tends to move positions if I shift in the chair and I have to reset it's position) and the headrest is not assembled symmetrically (one of the screws that holds the mesh net frame is not driven in as much as the other causing it to look and feel uneven) there is no way to correct this myself without damage to the mesh webbing on the headrest.
This chair is great and worth the money! Easy to put together all tools included. Beyond comfortable. The added headrest is great as well. I am 6'2 260ish male and holds my weight great! I can say by far the best office chair i have sat in. Working from home now long hours this chair does wonders. Also has a small lumbar device to adjust behind the seat.
After WFH since this pandemic garbage happened I finally decided to get a more comfortable chair. This one for the price has been great so far. The neck/head rest is a bit forward leaning for my liking but it can always be removed. So far I've left it and have it set lower on my neck so it's not as far forward. Overall though it's a pretty great chair!
