A toilet seat lifting and lowering device, i.e., one that does not require use of or touching with the hands is disclosed. The invention comprises several improved embodiments for not only making the lifting and lowering assembly more simplified but also for counterbalancing the seat and lid against the pedal. In preferred embodiments the invention comprises a torque transfer assembly comprising two interacting cams that can, depending upon the embodiment used, designed to be self limiting in their rotational travel such that the arc rotation of the seat travels from horizontal to about vertical. The apparatus further has a friction-regulated tension assembly that acts to attenuate the rate of drop of the seat while a separate friction structural arrangement between the seat and lid provide for a differential lowering rate for the lid thereby eliminating inherent slamming down of the lid onto the seat.
