Abstract
A portable stage platform includes a platform assembly having a mass and being shiftable between a stowed configuration and a performance configuration. The platform assembly has a platform that presents an upwardly directed performance surface when in the performance configuration and an opposed underside. The underside has a plurality of collapsible legs operably coupled thereto. The collapsible legs are shiftable between a collapsed configuration in which the collapsible legs are substantially flush with the underside and an extended configuration in which the collapsible legs are substantially transverse to the underside. The portable stage platform includes a platform base assembly that is shiftable between a stowed configuration and a performance configuration. The platform base assembly has apparatus for counterbalancing the mass of the platform assembly in order to minimize the effort required of an operator to shift the platform assembly between the stowed configuration and a performance configuration.
