Genuinely the best and clearest instructions on flat pack furniture I've ever seen. Each step is in a separate bag, you can't go wrong. Take special care when nailing the back board on, if you do a nail at an off angle you can accidentally pierce the walls on the shelf. Two shelves have fixed positions, the other three can be installed at 1 of 3 heights - very flexible, particularly useful if you very tall art books or photo albums. Looks very handsome.
