Waterbed mattress with equalized edge support

Image Number 2 for United States Patent #5172438.

Waterbed and mattress having a pair of elongated buoyant members are near the side edges of the mattress to provide additional support for a person resting near the edges of the bed. This additional support tends to equalize the support provided along the edge and toward the middle of the mattress so that a person resting near the edge remains in a level position. In the disclosed embodiments, the buoyant members are fabricated of a closed cell polyethylene foam and are attached to a wave reducing baffle structure which is also included in the mattress.
