This chair is quite comfortable to sit in even for 8hrs straight during a work day. The mesh is strong and breathable. The lumbar support is adjustable and feels much much better than a chair without lumbar support. If I ever need another office or computer chair I will buy a second one.
The concept of mesh is nice with the nice headrest. The lumber support piece broke off very soon and not it hurts/pokes in your back. I believe the build quality of that particular piece is not good. I would not recommend for long seating for 4/5 hours Would not buy again
