I love the chair. Big and very comfortable. The only reason it is getting 4 stars and not 5 is the paint is already chipping off the side of the chair. It's 3 weeks old and the paint is already coming off. Other than that it is worth it.
I can only compare to the ancient wheel-less chair I replaced but this was an excellent purchase. I spend the majority of my day and my desk and my back no longer hurts at the end of the day. I love this chair.
