This is a pretty awesome concept.
Take an old furniture store with a massive floorplan and fill it with about six bajillion trampolines and you've got Jumpstreet.
The kids love it and there's plenty of adults in on the fun also. There is an area for the smaller kids also. I was pretty impressed with their attention to safety in there.
It's pretty pricey, but what isn't in the world of niche family amusement establishments anymore.
They apparently also have trampoline dodgeball. Which is awesome. So, yeah, get on that.
