Dear Crystal, While our recommended age range for all inflatables is 3 and up, there is no designated age group for any of our inflatables. These items typically are not limited by age as much as they are by user weight. All of our commercial grade products (such as the Magic Castle 10) can support users up to 200 lbs. As long as you abide by the limits of 200 lb per user and 600 lbs total, the Magic Castle10 can support any age group, even adults!
