Your review: Comfortable and stylish. Leather feels very nice. Easy to put together. "Flip-Up Arms" implies some sort of action, or mechanical function, however these arms don't move at all. I am 6'1" about 220lbs and it takes effort to make this lean back. I replaced the standard casters with roller blade casters, making it sit a little higher, putting the arms right at 30", so no need to use the pneumatic to raise it up to desk height.
Pros: Metal framing makes it sturdy and strong. Larger than most office chairs so it doesn't lean back easily, which is a plus to me.
Cons: Standard plastic casters, which are noisy on anything other than carpet, and can leave marks on tile/concrete/wood, etc.
