The sensational bouncy castle is a dream playground for children (and their parents). This bouncy castle includes a handy 220/240 V integrated pump to save parents hours of inflating it. Just plug in the castle and it inflates in 4 minutes. Once the castle is inflated, kids will love having fun with the 50 included balls that make every jump even more fun. The mesh walls allow parents to watch their children at all times. Additionally, the castle has a single, non-removable door that allows children to enter and exit without tripping or falling. It also allows them to develop their motor skills. The built-in pump also makes it easy to deflate the castle for quick storage after a party or night out.
