The Kelburne Luxura Leather Computer and Desk Chair is very comfortable especially for my back. I certainly would recommend purchasing it to my friends.
This is an okay short term chair. If you need a chair for 5 minutes here and there this chair will last you for a while. If this is used as your study chair or office chair that you will use a lot I don't think it's going to last long. You get what you pay for. I bought this chair on sale and I feel that the quality is relative to it's cost.
