Why not take it to the next level, and have it down in a pit six feet below ground? It would be fun to jump in and out. You could embed the hard edges in the walls of the pit so only the bouncy part would be exposed.
True, people would accidentally fall in from time to time, but they probably wouldn’t be badly injured. And you would have to haul out the trapped dogs, cats, deer, etc. every once in a while. And leaves, grass, trash…
OK, add an elevator underneath it to lift it to ground level! That eases removal of wildlife and rubbish. Plus it lets you adjust the depth for the little kids.
