ABSTRACT:
A cushion apparatus includes an enclosed cushion member defining an interior cavity defined by a top wall spaced from and parallel a bottom wall, with a surrounding side wall coextensive therebetween. A portal opening is directed through the side wall, with the cushion including a viscous fluid such as oil defining a medium therewithin floatingly receiving hollow spheres of varying sizes that are deformably constructed in floation with the viscous fluid. The viscous fluid volume is less than a further volume defined by the internal cavity of the cushion, and the hollow spheres define a spherical volume total less than the volume of the viscous fluid. A modification of the invention includes resilient spheres mounted within the fluid medium of varying diameters, with a ferromagnetic rod mounted diametrically aligned within each sphere, with each rod extending a length less than a predetermined diameter of each associated sphere, with a north pole of each sphere extending coextensively along with an outer surface of sphere to effect magnetic repulsion and constant agitation with the cushion in use.
