Huge and very durable. If you don’t own a blower, you need to purchase that. My grandchildren are 6, 4 and 2. They love it. Especially good this summer with so many restrictions.

Was looking for something for our son during the pandemic since everything is closed and his birthday is this month. This blows up real fast and breakdown is super easy. All the kids love it.

I have a 7yo (approx 60lbs) and a 3yo (approx 40lbs) I purchased this for. They love it. We have it set up in a large open area in our basement. We put plastic balls in the pool area of it. The max amt. of kids that have been on it while we've had this is 4. (Two 7yo, 4yo, & a 3yo) It held up great. I have allowed my kids to get pretty crazy and rambunctious on this and it hasn't tipped over. 1 time it looked like it was going to start tipping but stopped. So far durability handheld up nice and they've played on it alot BUT we've only had it 2 weeks. Overall I would recommend this and it was a good purchase.
