We just bought this for our teen son's bedroom.  Its OK but I don't love it.  As others have noted,  the instructions are crummy, but we did not struggle much putting it together.  Its not all that big -- there is a 4-tier one for only a little money.  So it depends what you want from it.  A bigger issue is that the shelf height does not fit larger books -- openings are just under 10".  Also, because of how it stands off the ground, its a bit wobbly.   Strudiness is fine - its just got a small base.  Bottom line, fine for a mixture of things, but don't plan to use it for lots of books.  

Pros: Moderate size and open look are attractive, and it does not overwhelm.  Sturdy enough.
Cons: If you want storage, especially for books, there are cheaper and more flexible options.
