Received the bookcase on time from Wayfair.  Packed well  all parts were in the box.  My husband  I put it together in about 1 12.  It took a while because the instructions were not specific about front  back of the black rods.  Wish the pictures in the instructions book were more clear.  The one other issue was when you connect the 12 circle rods.  It took a while  muscle to line the rods up correctly.  One tip I would give everyone is to not tighten up all the bolts until you have it together.  It helps line up the openings to place the bolts.
All in all I’m very happy with the book case.  The dark wood is pretty  I love the black rods.
We did anchor it to the wall for safety.  If you don’t it will tip over easy.
