My chair was simple to assemble and is extremely comfortable. I have a at home computer job so i'm it this lovely chair most of the day it has been very nice.
When I sat in it it felt great in the store. When I got home and put mine together it also felt great but after ten minutes or so the right arm broke off while getting up on the left side. The left arm had any weight on it the right just my hand. If I had been getting up on the right side I most likely would have been injured. I took it back and got a "better" quality chair which doesn't fit my back as well but has a 500 lb load rating since I am 200 lbs it should last longer even if not as comfortable. So the rating is a very disappointing low rating.
