ABSTRACT:
A toilet seat apparatus includes a platform having upper and lower surfaces, a circular opening extending therethrough, an outer edge and an inner edge. Each of a pair of panels has a first end and a second end, and a first edge and a second edge. The panels are positioned on the platform. The first and second edges are arcuate such that the first edges may be aligned with the inner edge when the second edges are aligned with the outer edge. Each panel has top and bottom surfaces. A plurality of biasing members biases the panels upwardly away from the platform. Each biasing member extends between and is attached to the upper surface of the platform and the bottom surface of one of the panels. A plurality of guide members guides movement of the panels toward the outer edge of the platform as the panels move toward the platform.
