It is typically made from durable, puncture-resistant materials and is filled with air to create a bouncy surface. Jumping castles come in various shapes and sizes, often featuring colorful designs and themes, making them popular for birthday parties and outdoor events. These inflatable play areas provide a safe environment for kids to enjoy physical activity while having fun. Many jumping castles also include additional features like slides or obstacle courses, enhancing the play experience. They are often rented from companies specializing in inflatable entertainment for events.
