re: Does anyone still sleep on a waterbed?

When I was a kid, some hippy types moved out of a shitty rent house. All of us kids went in the vacated house to explore. They left behind the first "waterbed" I ever saw.

It was just a "mattress" made out of thick black rubber like a truck inner tube, full of water, on the floor. Nothing else. I don't think it even had baffles in it.

It was strong though. We used it like a trampoline, and it never popped.
