small indoor trampolines

[troutpout]

Ds used to have an elc indoor little trampoline which he loved. He got too big for it(weightwise) years ago and it tore.
We would like to get him something else. Like a grown up version basically. He has asd and dyspraxia and it would be a huge benefit for both. It has to be indoor (we have no garden to speak of (a tiny concrete yard).
What i want to know is if anyone has any recommendations of small indoor trampolines that can take a larger weight (he's 12 years old...weighs about 6 stone). I've seen those kind of 'sporty' trampolines that you get in argos etc...but wanted to know if they are properly boingy or more like 'trampettes' (a bit of give but no proper bounce iykwim).
Any ideas/experience?

we bought the'my first trampoline' from woolies,it was £49.99 and its great,
they also have it in ..argos
toys-r-us

my dd(3) and ds(4) love it, they both go on at the same time(along with the dog sometimes!lol)and its fine,(hubby was also on it when we built it,he's about 9-10stone lol)
