Part were not marked or holes did not line up or were not drilled right.  The whole thing was a mess.  It took my husband and I a week and a half to put this thing together because we got so Frustrated with the poor workmanship we had to keep walking away from it before we throw it out to the road.  We finally worked it out and it’s together and believe me it’s not to the direction that came with the bookcase.  We just had to wing it.  I think you owe us our money back.  This is a terrible product.  Stop selling it.
