There is nothing children and adults love more than bouncing, whether on a trampoline or bouncy house/ castle. There are some great outdoor trampolines on the market to consider. If you have the space and are happy to have a fixed piece of equipment then some of the larger safer trampolines are a good idea. But is you want to save the bouncy fun for special occasions and have less outdoor space, then buying an inflatable bouncy house is a good option. They can also be easily deflated and stored away when not in use.
