You do get what you pay for. This shelf is held together by wooden pegs and sticky strips (no nails). It's lightweight because it's a manufactured material. This bookcase was fine as long as it was sitting in the corner undisturbed (although it did manage to carry a lot of weight from books). But it did not survive a move. Went to pick it up and the sticky strips holding it together let me down. If you want something that will last, I recommend looking at real-wood products that are held together with something more than tape.
