I wish I could give this zero stars.  It's awful!  I have no idea how it's rated so high as the quality is terrible.  Each shelf has a pre-drilled hole (which you don't end up using for most of them so it's just left open) that happens to land right at the shelf support so the shelves are unsteady and if you push down on the corner with any pressure at all, the shelves split.  If we hadn't already spent hours putting the stupid thing together, we'd be sending it back but we'll keep it though we only expect it to last a year if that.  And won't be able to store anything heavy on it (you know, like books which you'd typically store on book shelves).  Ignore the 4 star reviews and steer clear of this piece of junk.
