These chairs are fantastic, i am giving a 4 star because the bottom of these chair feet are very floor negative.  The manufacturer should have something on them as they are destructive and harsh.  I have used the stick on felt and found a nice rug to put under most of the feet.  I will be keeping an eye on them as the way the feet are they will throw the felt and scratch if moved.
The chairs are beautiful, not as green tinged as I had hoped, but we just love them as a conversation place in front of our beautiful view windows.
