I am someone who does not lean back when they work. Even with the reclining function in lock mode I find that it does not give me the support I need to work more upright. Previously I had a chair that had more customization functions and that's probably what I should have bought. Otherwise a good standard mesh task chair.
So far I am really loving this chair. Took only a couple minutes to assemble and was very clear. and I know none of us WANT to be sitting in an office chair all day but if I HAVE to be... it's a pretty good one! No complaints.
After about an hour my legs hurt and then fall asleep. The front edge of the chair is cutting off the blood circulation in my leg. A seat slide adjustment would be a bonus. It's only been a week. Maybe the chair needs to be broken in.
