| 摘要 |
The present invention provides a waterbed mattress 10 having a slab 18 of open celled foam e.g. polyurethane substantially submerged in, yet partially suspended above the upper surface of, the liquid fill of the mattress. The waterbed mattress retains the positive qualities of buoyant support and comfort of conventional waterbed mattresses, and reduces the undesired wave motion often created within the mattress. Other embodiments include a waterbed mattress having a large number of open celled foam particles which will be substantially submerged in, yet partially suspended at the upper surface of, the mattress's liquid fill, such particles being either enclosed in a gauze-like sack or unenclosed within the mattress. The present invention may be incorporated in waterbeds or other body supporting furniture such as chairs and couches in which a liquid fill medium is used. <IMAGE> |
