Beautiful lamp ! Very easy to assemble and sturdy. The marble base is 15" in diameter and 2" thick, so it is very supportive and will keep this lamp from tipping over in almost any circumstances. Nice to be able to adjust the angle of the arcing piece. I have read reviews where people were confused about the colours: I chose the "nickel" finish and the shades are more like a "winter white" shade... not white white, but not off-white either... something in between. It's more like cream or very light ivory. Looks great.
