Yeah, I saw that it looked as though it was bungee suspension... but is it really just one complete bungee cord? I could understand 6 or so big ones intertwined, but if it's just one, and it breaks due to abrasion or the no sock dance then you'd be SOL, right?
There are actually 4 large bungees. One on the top where your head goes, one on the bottom where you feet go, and one on either side of where your torso goes. THe "breaking" of one was my initial thought, but I decided that even if one brakes, it can easily be retied by missing one or two loops, and still provide ample support. Otherwise, it would be VERY easy to get rid of the whole bungee and tie it with some cord or rope.
