Although the chair is a great price i was disappointed that the head rest did not fit correctly. As I assembled the pieces all the parts were correctly labeled and the instructions were clear. (Please don't tell anyone that I read or even looked at the instructions.) However as i installed the headrest it does not fit it cannot fit and the bolts cannot be inserted without a slight modification to the assembly. A small little piece of plastic must be cut way for the headrest to slide into the back of the chair and the bolts inserted and tightened. It is such a small and minor mistake in the finishing of the plastic but the headrest cannot be installed without the slight modification.
This chair is great! It is great for using for work all day since it supports your back and all the material is mesh (back bottom and head). Pretty easy to build as well.
