Recently bought and just got it put together.  It took some time because I had to stop and restart a lot with helping my wife with 3 under 5 years.  Everything went together pretty well.  Some additional pilot holes on the roof frame, and a few other areas would have been helpful in assembly.  The slide completely in its slots for the rails was short on the one end was a little short and made it difficult to put on the main structure.  Lastly the exterior of the wood peeled from varnish coating on it, prior to assembly even. 

All said, it’s very stable and looks great and my children are obsessed!
