I'm heavy, some might say "dense for my height". Okay, it's just me who says that. But, yeah...and I flop around a lot in my sleep too. I just don't trust anything with one connection into interior studs I also don't trust. Perfect recipe for me never sleeping again. I like over-engineering things.
I've been sleeping in a giant beanbag for the past year to try to break myself of sleeping on my stomach. Not working. I do think I have learned to sleep in an inverted banana position now, though.
