What I Like most about this play set is that it comes with EVERYTHING you need!   All pre cut wood, brackets, swings, slide etc.  I would say this is perfect for a 4-7 yr old.  They only cons that I can think of is that the wood is not labeled-so take 15 min in the beginning and label all the wood this will save you a lot of time and frustration.  It took us approx. 5 hours to have it completely done.
