My main reason buying this chair was to get some back support since I sit 8 hrs a day on this chair. I'm petite and short (5' tall) so when I bought this I was afraid it won't go up high enough to my computer desk. But it go up pretty high so I'm pleased with that. Loved everything about it except it's not really supporting my back as I wanted. It would be nice if the back pop in more to touch my back. Again maybe because I'm petite so I don't know. That's why I'm giving it a 4 stars instead of 5.
The chair is very comfortable with many adjustments. It would have been nice to have the adjustment for the seat pan. Fortunately it fits me fine the way it is. My wife will struggle with the depth of the seat.
We bought two of these recently. The mesh seating is comfortable once broken in but one of them 6 days in started having staples off the right side of the seat pull out where it was attached to the frame. Fortunately the store swapped it out for another one with no problem. No issues since with the replacement.
