Very bottom of the base is Rozen the two part of the base is steel and the mechanism for the pole string is metal and plastic. The shade interior is plastic E but I don’t know the exact material and the outside of the shade is fabric overall, a very nice set of lamps that will go anywhere and they are the perfect height for my bedroom which is where I place them. I did receive one shade that was dented and WAYFAIR had no problem sending me a new one.￼
