I enjoy this chair. In the past, I purchased at least 4 bonded leather office chairs and in the end the material started peeling from age. This chair feels light and airy. It allows you to breath if I may use the terminology to describe the material. I like the lumbar and the  head rest. 
The chair have comfort settings which allow me to set it to my preference. Very comfortable and took only 40 minutes to put together. Very easy, illustrated instructions. Da Wife has a leather office chair and wants to switch, but no, no ! I have only had it a week, so I have to come back later and give you an update !
