Abstract: A toilet seat for maintaining a stable engagement with an existing toilet base includes a body suitably sized and shaped for conforming to a top rim of the existing toilet base. The seat includes an outer flange statically coupled to a bottom surface of the body and extending downwardly therefrom. The seat further includes first and second inner flanges adjustably coupled to the body and juxtaposed adjacent to the outer flange. Further, each of the first and second inner flanges include a rubber pad directly attached thereto in such a manner that the rubber pads frictionally engage the inner surface of the existing toilet base top rim. The flanges further include first and second deformably resilient spring members which have a corresponding top end anchored to a curvilinear inner face of the first and second notches respectively.
