I'd imagine more like Scrooge McDuck in swim trunks diving into a large vault of gold coins.

Also, I doubt there's really a matress. He just sleeps on the money directly. Stacks of banded bills is probably pretty stiff vs just loose bills all piles up organically. Like each night before bed, he takes a few new stacks of cash reserves and makes it rain before diving in.
