Very easy to setup and though I have never done stairs before I was able to finish my stairs (cutting and fitting) in one afternoon.  It was a total of 19 treads and risers.  My neighbor had a pro do his stairs.  Took the pro over 3 weeks as he cut the boards wrong and they had to reorder the treads.  He came over to see mine thought my stairs were done much better.  Doing stairs, get it.  Ignore whiney reviews about quality.  The shipping tube it comes in will protect it.
