I got this because of someone's review saying they were over 5 ft and could stand up in the fort! I have a 12 and 9 yr old. As well as a 1 and 3 year old. And it's perfect for everyone! I was really searching for a set that everyone could use and not just the Littles and this was perfect! Th older ones lover the rock wall and fort and the Littles love the swings and slide. It took a whole weekend to build, but mostly because my father in law wasn't following the steps in order so they had to back track alot. Also, expect to seal or weather proof your wood before building, as it is not sealed and we didn't know until after it wa built and it was a pain to seal it while put together. Love this set for my babies. They are so spoiled and happy
