Abstract: Non-slip ergonomic pads are disposed on opposite sides of the upper surface of a toilet seat for supporting the gluteus maximus of a user while helping to align the pelvis and spine when the user is seated on the toilet seat. The pads are formed of a durable non-slip material which deforms slightly when sat upon and has a memory to return to its original form when the pressure of the user seated on the toilet seat is removed. The pads may include a single layer or multiple layers of open celled sponge rubber or other material. When the pads have multiple layers, the layers may exhibit a continuous gradient of values of indentation force deflection. The material should be of substantially uniform thickness so as to provide uniform pressure distribution and firm support. The pads have non-slip characteristics without being sticky to the touch. The pads may have a cloth surface layer to provide a printable surface to contain printing, advertising or a design.
