It’s way bigger than expected. The padding around other trampolines takes up some of their diameter measurements making their usable jumping surface less than the number on the description. This one is designed with slimmer padding and makes for a huge area to hop around in. I have a 5 and a half year old and a three year old, and both can jump on it quite easily without running into each other. It’s a good fit for this age group and the bounce is amazing! I think it’s great quality too. I’m happy with our purchase, and I hope you can snag one too!
