Brown leather office chair $55 OBO (a week old, retailed at $99)

I'm selling this really comfortable brown leather office chair from Office Depot that I've had for about a week. But I recently invested in one of those exercise balls that you sit on at a desk, so I don't need it anymore and can't return it because it's already assembled. It came with arms (though the picture doesn't show that) which I can attach before you pick it up, but I didn't need them so I left them off when I assembled it. Let me know if you're interested! Willing to exchange anywhere on Stanford's campus, or I can drive it to you if needed.
