Tis piece is very complicated to put together. Also, some of the pre cut holes were not cut all the way through so we cannot get the screws is.  I would have sent this back, but my husband already started trying to put it together and he threw the box away.  I would never have ordered this is I had known how difficult it would be to make ready to use.  I've bought many things on Wayfair and have never had this problem before. I am so disappointed and wonder if this will wind up in the garage as garbage.
