This vintage bamboo 4 tier bookcase/etagere folds almost flat for perfect storage. Its shelves fold down and lock into the sides with wooden bamboo dowels built into the bottom of each shelf. The shelfs are strong and can hold a good amount of weight,whether it is books or other items, it gets strudier as items are placed on the etagere. Shelves are 10" deep. The last picture shows both the etageres, I am selling them separately, but they are a matching pair, if you need both.
