The chair is very comfortable for working in for 6+7 hours. A lot of lower back support is provided. It also has adjustable armrests that go up and down. I would recommend this chair
I like the adjustability of the chair the back support is nice and the head support although quite goofy looking really does feel good if you lean back. The casters on the other hand sucked and I had to replace them within 2 weeks. I rolled off the edge of my chair mat and all of a sudden that little bit of imbalanced load was enough to start them scraping thier plastic housing. My new $30 super casters work great and the chair is still very comfortable but after adding the extra $30 worth of casters I probably wouldn't have considered it.
Well laid out parts + easy instructions = simple & fast assembly. Had it for 2 weeks now and it is very comfortable. I went with mesh over leather and I think it was a good choice.
