I don't have a backyard trampoline at my house. We go to a local store that allows us to jump on the trampolines in the showroom (for a nominal fee). I did buy a Springfree trampoline for inside though. My son was destroying the round mini-tramps that are used for exercise. Springfree makes a small rectangular trampoline for indoors. It is approximately 3' x 5' and has the same type of plasic flex springs. It is holding up really well to the abuse my son puts on it. Cost...not cheap. I paid $400 for it.
