ABSTRACT:
A rail assembly is formed of rails equal to the length of side faces of a waterbed. Each of the rails has a common cross sectional configuration. Each of the rails has a flat rear face and with sloping faces. The sloping faces extend forwardly and terminating in a groove. The groove has inwardly extending parallel surfaces. The parallel surfaces have a common spacing and terminate in a semi-cylindrical surface. Coupling components include screws. The screws extend through the rails. The screws are adapted to couple with sides of a waterbed. A plurality of similarly configured rods each have a cylindrical configuration. The rods have a diameter slightly less than the spacing between the sides of the groove and the diameter of the semi-cylindrical surfaces.
