I love the way it looks, and the wood parts are heavy (!) and sturdy, but the overall structural design is dismal.  Beware: the glass pieces are LOAD BEARING.   If you shatter one, particularly the bottom one, the whole (very heavy) bookcase collapses.   If  you press against the side of the EMPTY bookcase after assembling it wobbles left and right in a scary way.  I did not feel the least bit safe using this.  (I suspect the original design was all wood, worked fine, and then some marketing person said, "Hey, can't we make this with some glass sides?  Beautiful looking, terrible structural design.  

I'm going to a building store today to buy 16 (!) white metal corner brackets which I will install in pairs at each "inside" wood corner.  Hope that works because other than this I love the bookcase.

But beware, ESPECIALLY if you have kids or big rowdy dogs, or drunks nearby.
