Nice construction and chrome legs/arms. I did have some issue lining up screws in the arm rests, I overtightened too early but once I loosened things up I managed to get everything set correctly.

I have it on carpet and the wheels are smooth. The high back is right. Tilt feels appropriate, nothing where I feel like I'm going to fall. The rise/fall action is smooth. The seat is firm but comfortable, the back is padded nicely. I have the white one against a black desk, it's super stylish! 

Added bonus, the arm wrest coverings unzip and can be removed for cleaning!
