This piece had multiple problems.  First, the instructions are not very clear.  Secondly, the top piece wasn't properly squared so the top left edge doesn't fit smoothly.  Thirdly, the predrilled holes for the back pieces were not done properly and most of them could not be used.  So the back pieces could not be properly screwed in.  Then the last straw was that one of the shelves wasn't cut properly.  So after spending a good hour and a half to put it together, the final problem makes this piece no good, as there were two slots cut on the end when only one slot was supposed to be cut.  So, I'm not sure I want to take another chance with this piece.  I'm waiting to hear back from Wayfair to see what they will do.
