It's actually not that hard to pack up one of those mattresses. You won't get it back into the original box, but you can make it a good bit smaller. You get a mattress bag, tape the end up, and cut a hole in the middle of the side and put a vacuum hose in it. Then walk around on the mattress until it's as flat as you can get it, and tape the hole closed.
