Easy to assemble although the directions are not fool proof but better than most such instructions. Chair is quite comfortable and easily adjusted for height and back pressure. And the price was right.
I've had this chair for approximately 10 months. I'm not an overly big person though I do work from home and I spent about 40 hours a week in it. So far it makes creaking and cracking sounds when I adjust myself as a result of not sitting on the base properly. Additionally the hydraulics are giving out so from time to time I sink to the floor unexpectedly. I would not recommend this to anybody except my neighbor who I don't particularly like.
I was a little concerned that this chair would be of poor quality because of the low price but after I put it together and now using it is extremely comfortable sturdy and built very well.. The only problem I had with this item is that UPS is absolutely horrible with their delivery service.
