Yes most of our inflatables are strong enough to handle an adult. If the maximum age rating for the inflatable is 14 years, that means it is constructed from commercial grade PVC and so will be strong enough to handle an adult. Please keep in mind that the inflatables are designed for children up to the maximum age rating, so they will not handle multiple adults or adults that get boisterous on the inflatables. We encourage parents to join in and have fun with their kids, but please respect the equipment. Any inflatable with a maximum age rating of less than 14 years will under no circumstances handle the weight of an adult.
