Although the equipment for the Dormatron is not seen, it is advertised on the in-game radio and an advertisement is seen in the instruction manual. It uses heat to exercise a person during their sleep to shed weight. The Dormatrom is strapped to the user's arms and legs, set to 11 and then sheds weight during their sleep. Lazlow praises the Dormatrom during Chatterbox FM. The beeline for the company is 1-800-SLEEPOFFLARD.
The Dormatrom is referenced in Grand Theft Auto: Liberty City Stories during the Chatterbox segment, where Lazlow asks callers to talk about sensible issues such as Dormatron bondage.
