This arrived so quickly! We set it up the next day and I was able to do it all in less than 10 minutes by myself. We tried it without water the first time and the kids had a great time. My 4 year old loves it but I can see he will also be able to grow with it and use it for years to come. There is a safety net at the top by the slide which was a main feature I was looking for. Great buy!
