Abstract
Abstract A portable stadium seat for use over existing bleachers or stadium seats has a rigid frame on which an inflatable cushion is provided. The seat frame may have pivotally connected leg and head rest portions. The seat cushion may have a head rest, a lumbar support, a back rest, a seat portion and armrests all formed as separate compartments selectively connectable by a manifold valve to a footpump which is carried in a compartment in the seat cushion. A "U" shaped seat hook is pivotally connected to the underside of the seat frame and in one position, it is used to attach the seat frame over an exisiting stadium seat or bleacher, and in another position, it is received in a catch formed on the back of the seat frame to be used as a handle for transportation of the portable stadium seat.
