This storage unit is well constructed if a little trying to put together due to the tiny allen wrenches you have to use. The wooden shelves are heavy duty and nicely stained. One thing I like about this unit compared with others I considered is that the shelves have a back to them which keeps items from falling off behind the toilet. My reason for 4 stars rather than 5 is that once I had it in place, the lid (not to mention the seat) of my elongated toilet would not stay up! It hit the bottom shelf and needed at least another inch and a half for clearance. I solved this by placing the four legs up on bed risers I happened to have. I’m going to keep it but it would have been good if I had thought to figure this out before I ordered it. Just FYI J
