A seat assembly for use in an automative vehicle comprising a seat back and a seat cushion pivotally coupled to the seat back. A pivot bracket is fixedly secured to each opposite lateral side of the seat back for supporting the seat assembly between opposing lateral side walls within the interior of the vehicle. Each pivot bracket includes a support flange for supporting the seat cushion cantilevered from the pivot bracket. A hook portion engages a latch post on the lateral side walls to retain the seat assembly in an upright seating position. A pivot flange is pivotally coupled to a main pivot post on the lateral side walls for pivoting the seat assembly between the upright seating position to a stow-to-floor position wherein the seat cushion is pivoted forwardly and downwardly to be supported on the floor of the vehicle and the seat back is pivoted against the seat cushion to form an extended cargo load floor.
