Purchased this chair April 2021 at first was very happy with it. Within the last 4 months the mesh on the seating area is coming loose from the frame. Even more irritating is that the hydraulic system won't hold. It will drop inch by inch until it hits bottom! I have to keep raising the seating over and over.
If you like to sit up straight don't buy this chair. It's comfortable if you like to be permanently leaning back a bit as this is the chairs natural resting position. It is also hands down the loudest creakiest office chair I have ever sat in. I cannot wd40 it enough to make any of it go away. I should have returned it when I had the change. It is wide cool and comfy otherwise. Great relaxing LOUD chair -.-
