ABSTRACT:
A waterbed mattress incorporates an array of individual tie structures each having an elastic element that is slightly stressed under nominal fill conditions of the mattress. The elastic element has a spring constant of about three pounds per inch. The tie structures determine the firmness characteristic of the mattress and accommodate to changing and/or shifting loads. Firmness no longer depends upon the degree of fill.
