Abstract: A toilet seat cover providing a flushable, foldable covering having a top side and an outer edge that cover an entire top surface and outer side, respectively, of a toilet seat having a forward open mouth. A channel centrally disposed in a bottom side of the covering has a continuous outer periphery with an elastomeric edge to accommodate insertion of the toilet seat therethrough to permit the covering to be placed onto the toilet seat. Straight foldable score lines disposed horizontally and vertically on the top side and the outer edge are arranged perpendicular to each other in a crisscross pattern of sections. The score lines permit transformation from a fully folded position with the sections arranged in a compressed, stacked configuration for packaging and transport to a fully unfolded position to cover a toilet seat.
