Abstract
A waterbed mattress has an internal horizontally-extending baffle for reducing wave-like motion of the water in the mattress. The baffle comprises at least two horizontally-extending layers secured together, a first layer denser than water and a second layer less dense than water. The first layer can be a porous mass of bound-together fibers and the second layer can be closed cell polymeric foam. The baffle, which floats spaced apart from the bottom wall of the mattress, is foldable and collapsible, so that the entire mattress can be folded for storage.
