Very disappointed with this purchase. I noticed that it said "PVC tubes," but I didn't realize how cheap they'd be/look with the wood. From the picture and the description, you expect most of the structure to be made of wood because it says that the primary material is "solid + manufactured wood," but the pipes (which easily make up close to 45% of the structure) are not mentioned again at all. Didn't look nice at all. Will be returning.
