The wooden slats and lumber framing are thin and non-standard size (the slats are about 1/4 in thick, there are some gaps between some of the slats, and the frame lumber is smaller than a typical 1"x2" board) which makes the quality is a little lower than desired. The cabin piece is also a bit rickety, but that is easily fixed with some metal strapping and braces. However, I am not completely disappointed. It is a nice layout, the instructions are easy to follow, and it will clearly serve its function appropriately. I just wish the lumber was of higher quality considering the price.
