My brother bought the same one and I highly recommend it. I would talk about it but I would just be repeating what Carmine said.I got this one from Ikea, it is out of your price range but you really should invest in your computer chair if you spend a lot of time on it, a great one can really help your back. This is very comfortable, the padding is good, the arm rests are great. I've had mine for almost two years and it is holding up well.
