ABSTRACT:
An improved waterbed safety liner includes a base sheet which underlays the watermattress, and sidewalls extending upwardly from the edges of the base sheet to surround the watermattress and contain any liquid leaking therefrom. In one embodiment, an inflatable air chamber is integrally formed with the upper extent of the sidewalls to overlay a portion of the watermattress and provide buoyant edge support thereon. In another embodiment, a chamber formed integrally with the sidewalls of the safety liner is equal in height to the height of the watermattress, and is inflated either with air or with resilient foam material. In a further embodiment, a triangular cross-section foam block is adhered to the sidewall of each side, with the hypotenuse of the block impinging on the watermattress.
