Abstract
There is provided a portable seating apparatus having multiple seating tiers and an understructure system that operates to extend the seating for use and to retract the seating for storage and transport. In the storage arrangement, the lower seating and understructure is capable of being substantially retracted into a portable housing. The housing is fitted with a system of rollers that operate between an extended condition to support the housing for transport and to a retracted position to lower the housing onto stationary foot pads for use by spectators. The seating apparatus is also provided with an anti-tipping mechanism which operates to limit tipping movement of the housing during use by spectators.
