This is a very comfortable chair. The headrest height may not be for everyone so you might want to take it off. For assembly i would recommend using the box it came with. You will understand why.
Very well made and designed. I like it but I think it was made for someone shorter than myself. I'm 5'8". The arm rests could be longer and the back and headrest a little taller. However the lumbar support is excellent. A good buy. Assembly was not too difficult but I am an 82 year-old female and there is quite a bit of lifting and twisting involved. Ignoto.
Sturdy comfortable chair. The mesh keeps you cool while sitting in it. The headrest is worthless though. I'm 6' and the top of my shoulders touched it so I had to remove it. However the chair is perfect without it so I didn't remove any stars for that.
