A sitting stool made up of a toilet seat with attached stool legs. It is used so one may sit as their partner lays underneath to be given easy access to give a rimjob. It is also used in scat play.

The more elaborate designs have the toilet seat attached by heavy springs to a metal frame. the springs allows the seated to bounce up and down as the person under tongue fucks their ass. this design is also called a Joy Rider
