The unit was more narrow than I thought.  It also has a very strong smell of stain/paint.  I don't think it is made of wood, but a processed wood-plastic.  On the good side, it only takes 8 screws to assemble the unit, the shelves are adjustable and come with very large shelf supports.  The smell is almost gone (it has been 1 week since I put it up).  One of the things I don't like is that the inside of the unit on the sides of the shelves, the back rails protrude into the cabinet. You loose about 1 inch on both sides, that aren't flush with the back.   I suppose it is the style of the unit, but if you like your books pushed all the way to the back, this may bother you.  It is made in China.
