This coffee table is all glass and is made out of heavy glass. It was easy to put together, but heavy to move into position.  Since you can't see it, you have to have a large area to put it in so you can get around it without falling into it and having an accident. And you should put something on it to signal its presence. This somewhat defeats why I bought a glass coffee table-to have an area of visual blankness in a room with a busy rug and lots of furniture.
