Hi Ashleigh, The Big 'Ol Bouncer can hold up to 6 kids at a time up to 100 lbs max. We don't have an age limit, but we do recommend that you always observe the rule for evenly matched players for safety reasons. It is important that players in a Bounce House or other Inflatable Play Structure are evenly matched in size, age, development, and skillset to keep everyone safe. Sincerely, Blast Zone Support
