How high?

Another end of a chapter as the trampoline is taken down signalling no kids in the house anymore. As a friend of ours has a 3 year old who wants this well used and rather tatty trampoline, I asked J to test it as I don't think it has been used at all this year. He couldn't of course test it gently, and he amazed himself at just how high he could get. Taller net required for 20 year olds?
