What kind of cusion required for a 'break-fall' from a little over 10 feet?

Have a show in September where I have to fall from a little over 10 feet onto a stage, making it look like i've fallen from the sky. Not landing on my feet, doing a 'break-fall' maneuver where I absorb the impact with my entire body and reduce possibly bodily damage. I have experience with break falling but i've never really done too much over 5 feet. What kind of cushioning will I need? Practiced yesterday at about 7 feet onto bare gr and was fine.
