Bouncy castles are a lot of fun for kids, but they can also be dangerous. That's why it's important to know what age a child can go on a bouncy castle. Most bouncy castles have a weight limit of around 200 pounds, so that's usually the minimum age. However, some bouncy castles have height restrictions as well.nnFor example, children under four feet tall may not be allowed on the castle. And of course, all children should be supervised by an adult while they're on the bouncy castle. With these guidelines in mind, you can help to ensure that your child has a safe and enjoyable experience on the bouncy castle.
