British Waterbed Company - FAQ Question 18
Will it fall through the floor?
We do not know
of any instance f a waterbed falling through a floor.
The weight of a waterbed is well distributed and the
pressure on the floor is less than that of a person
in a bath or a free standing refrigerator.
Because a waterbed
rests on a purpose built plinth, the floor loading is
not only well below the basic requirements of building
regulation, it is often less than 10% of the contact
pressure of a conventional bed on legs or casters. Millions
of waterbeds sold throughout the world have failed to
penetrate a ceiling and the majority of those sales
have involved the heavier rigid-sided systems.
