Made of metal. Very nice.

I looked a LONG time for the perfect light. I wanted something that had arms that swiveled and shades that were adjustable. My living room would not support an arc armed light because it was too overbearing. This light fit the bill. The arms can be moved so I have light focused on my chair or light focused on my couch and coffee table(where I do puzzles) or both. Can't wait to see how well it lights up the puzzles. I gave it four stars for two reasons. First, it is very pricy. Second, I wish there was a way to choose which two lights come on together. When you turn the switch, you get one light or two lights or all three lights. The color(bronze) is beautiful and fits my decor nicely.
