This is the creakiest chair I've ever bought. 
Cons:
It creaks every time I shift my weight (I weigh 160 lbs). 
It is smaller than advertised: the highest setting is lower to the ground than most office chairs, and the headrest barely reaches my shoulders (I am 5'9''), providing no head/neck support. The title of the product is misleading for these reasons. 
Pros: 
Easy assembly that comes with white gloves
Lumbar Support
