The top, sides, and front are made of sturdy wood. The back panels, however, are flimsy and light. I am not sure why one more piece of heavy duty wood could not have been used in its place. It did take over an hour to put together.  The box the pieces arrived in was nearly as big as the finished piece, so why not just offer a fully assembled cabinet?  The color is even and nice; the finished piece is a lovely addition. I would have loved five or six spaces on the inside, but four is still OK.
