This is a nice narrow shelving unit.  The shelves are deep enough to hold many different objects but not too deep to stick out in the room.  I have it in the kitchen on a narrow wall; it fits perfectly.  It comes with hardware to attach to the wall to keep it from tipping, but I didn't use it (not absolutely sure I will leave it here), however, it doesn't appear it will tip easily.  It feels well made.  I assembled it myself and except for one shelf, it was very easy.    I really like this shelving unit and may get a few more.  I recommend this piece if you are in the market for a narrow, tall shelving unit.
