Take the easy way out why don't you! Meanwhile, I think it's more fun to contemplate the possibilities.

I'm thinking I'll build a multi-story, Tempur-Pedic mattress maybe on top of shallow lake. Put some nets around it that extend high into the sky. The person landing on it gets cushion from the water and compression along with soft surface. Will hit it, slow down, and any bouncing contained within nets. Just need some idi... brave adventurer to both fund this structure and use it.

Note: Too great a chance of bouncing outside the nets. A spring or rocket activated top could help but hurts as much as the ground. Make hamburger out of them probably. So, a parallel, Tempur-Pedic surface that springs across the top or is moved into place with helicopters. That should be safer for high-energy, upward bouncing.
