It is a very good product. Not perfect, it is not a solid wood, but  well built, very sturdy and roomy without taking too much space. We live in apartment and space is in a great demand. This bookcase allows you to use effectively both the vertical space and horizontal one. There is one fixed shelve at about 30" height, the rest of them are adjustable. I wish shelves were a little bit deeper. They fit books and thin binders well, but  thicker binders will have about half of inch overhang. Yes, one more thing - it is really heavy, you need to men to carry it.
