Abstract
A tiered or platform-type seating unit which, when in a collapsed storage position, can be oriented in an upright position and is provided with support rollers which enable it to be moved about, including permitting passage through doorways. When in use, the unit is vertically rotated 90.degree. to position load-bearing rollers thereof in engagement with a floor. The platform unit includes a base platform having a first raised seating tier fixedly associated along one edge thereof. A second seating tier is positioned adjacent the opposite edge thereof. This second tier is movable from a lower position into an upper position so that this second tier is at an elevation above and spaced rearwardly from the first tier, there being an intermediate aisle therebetween. This aisle stores therein, when the unit is collapsed, a pair of removable platforms which are locked between the first and second tiers when the second tier is collapsed. These platforms can also be positioned on the floor in front of the first tier to define a third tier which is disposed at an elevation below the first tier.
