I purchased this swing set for my grandson last winter. The weather in our area is warm most of the time, so he was able to enjoy having fun and playing with all features of this set. For the summer, his father built a sandbox for the lower level for the grandson. This added feature is easy to make and pleased him even more. I was pleased with the quality of the set. For the money, we got a lot. When my grandson gets too tall for the inside of the tree house, an extension can be added with a different roof.
