I work 8+ hours in this chair and it has been very comfortable!  At first I had doubts about the cushioning appearing thin, but looks can be deceiving. It is super soft and molds perfectly to my back.  I got it in the gray color and I like that it does not stain easily.  I was worried about the my denim jeans transferring to the chair material but that has not been an issue.  It was very easy to put together; the only tools that are required was the provided allen wrench to attach the arms.  Everything else slid right into place!  I am very happy with my purchase!
