A seat stowage system for a vehicle having a spare tire tub comprises a seat assembly including a seatback cushion having an occupiable surface and an opposing cargo load surface and a base cushion having an occupiable surface and an underside surface. A translational joint assembly operatively connects the seatback cushion and the base cushion. The translational joint assembly allows the seat assembly to transition between an occupiable and a stowed position while utilizing the foot well and not interfering with or obstructing the spare tire tub.
