1. A self-lowering toilet seat system comprising:
a toilet bowl;
a toilet seat configured to be sat upon by a user;
a hinge rotatably coupling the toilet seat and the toilet bowl, the hinge configured so that the toilet seat is transitionable between a down position and an up position;
a lowering device configured to self-lower the toilet seat towards the down position;
a mechanical delay system configured to cause a seat time delay before the lowering device causes the toilet seat to lower towards the down position, the delay system being substantially sealed within a housing, wherein the delay system comprises a suction cup and an attachment surface, wherein the temporary coupling of the suction cup to the attachment surface temporarily prevents the seat from self-lowering to the down position.
