ABSTRACT:
A waterbed structure, in which added lumbar support is provided by a padded cover atop the bag (which also provides extra thermal insulation and padding). The padded cover includes a sheet of convoluted foam which covers essentially the full length of the mattress. This sheet of convoluted foam is stiffened, over the middle part of the mattress length, by a complementary piece of convoluted foam which is mated with it. The increase in thickness caused by having two pieces of convoluted foam face-to-face is relatively small. Thus, this arrangement provides extra firmness under the torso, while maintaining an essentially flat upper surface.
