Although when put together this looks fantastic and is very substantial, it was a nightmare to put together. It took several people 15 hours to complete.  The roof panels fell out over and over again. It was necessary to duct tape them into place while the others were installed, because they cannot be secure until all pieces are in.  The construction of the roof was terrible.  It required being on a ladder and inserting the small triangle pieces from above it, which got a little tricky when it came down to the last set.  No wonder Wayfair charges $600 to have someone set it up for you.  I recommend reading the manual several times, watching the quick youtube video a couple times, having several people to help, and lots of hours to spare.
