Chair is just not built to last the mesh is stapled to the chair in poor fashion and it start to sag within a month and it will totally separate within less than a year. Maybe if you are less than 120 pounds this will be good for you.
The only thing keeping this from being a five star rating is the height adjustment. I need it to be taller for me (I am 6 ft-3 in). The lower back support is good for those extended times at the desk. The mesh seat and back are a necessity for the breathability aspect. I tend to get too warm in a traditional chair. Height and reclining adjustments work well and are similar to other chairs making them easy to use. Very easy to assemble and does not require additional tools beyond that provided with the chair.
After purchasing this wonderful chair I couldn't live without it. It help me with my poor back posture. Previously I was suffering from pain with my old chair. This chair aligned my poor back and gave me my posture back. Thank you!! It would be more comfortable if it has a bottom cushion to sit on but that not the main point. The price was a rock deal to die for. Not all the chairs has head rests. This one gave it a bonus deal. I nearly fell asleep on it or maybe I was just tired...hahaha. But anyway love this chair very much. Go give it a try.
This chair arrived quickly. It was easy to put together the allen wrench you need for assembly is included. The parts are heavy but it gives the chair a very solid feel. The mesh seat and back are very comfortable.
Received the chair yesterday and got it assembled without too much hazzle BUT... some "Genius" decided to place a "Do Not Remove this sticker" in plain view on the back of the chair so it will constantly be visible. White glue remains on the metal if you try to remove it .. what a shame.
