Beware the instructions for putting this together are atrocious and quite complicated.  The box is extremely heavy and if you read the fine print weighs over 50lbs.  This is a project for someone who really enjoys DIY.  I still haven't put it together yet but the pieces are of high quality and I am sure once it is complete, it will be perfect for my nieces. 

I think next time I will purchase one that is already built.
