We LOVE this product. Our son is almost 4 but is very tall for his age.  He is  high energy & loves being outdoors. Dad can put it up in minutes & put it away almost as quickly. We've had kids as old as 9 playing in there & it held up wonderfully. A friend puts hers up in the basement during the winter so it can definitely be a year-round toy if you have the space. I rarely feel the need to review products unless there is something seriously wrong with it but this has turned out so well that I just had to share!
