Hi Leah, The Big Ol Bouncer is designed for children weighing up to 100 lbs each. It is suitable for 10-year-olds as long as they are 100 lbs or less. This particular inflatable can support up to 6 kids at a time as long as they are all 100 lbs or less. It is recommended to consider the input or interests of the 10+ kids in question. We find that while some "big kids" love the Big Ol Bouncer, some do prefer inflatables with more interactive features, like slides. Ultimately this does depend on the individual. Sincerely, Blast Zone Support
