Yes. Once at the sister in laws place back before they were well baffled. They held 300+ gallons of water and often collapsed apartment floors. If anyone moved the surf was up. Never again.
More like 235 gallons for a king. I spent 30 plus years in firehouses and never had or heard of a waterbed collapsing through a floor. Not saying impossible but pretty unlikely.
And we had one in the 80s like a lot of people did.
