Horrible product.  I never write reviews, but I didn't want anyone else to fall prey.  We spent 5+ hours trying to assemble and finally hired a professional.  He validated our frustrations as the bolts did not fit the slots and pieces weren't aligned properly.  He called it a piece of junk.  He finally got it put together as best he could and it broke after one night of play.  Don't waste your time, sanity or money.
