ABSTRACT:
An improved adjustable waterbed mattress with hydrostatic wave absorption comprising a water-inflatable bag-like enclosure containing therein a non-woven or very loosely woven expanded fiber product, unbonded or fixed with a binder to the same or another fiber product, which resists decomposition in water. When a user sits or lies on a conventional waterbed there is a tendency to sink or bottom out especially on the edge and an undesirable wave front is created in the waterbed mattress. The provision of the subject expanded fiber product in the waterbed mattress of the present invention substantially mitigates and dissipates this wave front and allows the bed to be easily packaged, filled, heated, drained and stored.
