Very large and easy to assemble. Timberline boots will definitely fit in any of the levels. Each level hold either three pairs of boots or four pairs of sneakers, and I am talking men’s sizes. If you build it as high as possible, expect it to lean forward a little bit. If possible, feel free to nail it to the wall, or simply remove two levels if you are not allowed to make holes in the walls. I personally built it as high as possible without nailing, and so far it is looking good and not shaky.
