It is an attractive shelving unit, but very cheap quality.  It was easy to assemble, but it did take quite a bit of time to put together.  The last thing to attach is the metal X shaped piece on the back.  I was worried to attach it because there was not pre drilled holes.  The pre drilled holes were not necessary because the "wood" is so soft, I pushed the screw into the 'wood" and screwed it in very easily.  The unit seems to be made of a heavy styrofoam with a very thin  veneer covering of wood.  I would not purchase again, it is expensive for the very cheap materials that make up the shelving unit.
