Abstract: The cargo carrier and sofa extension includes a pair of platforms articulated to one another along adjacent long edges with the forward platform being coupled to hinges behind the rear seat of the vehicle. Brackets are provided along opposite sides of the vehicle to support the platforms above the vehicle floor when the platforms lie in an extended position. In the extended position with the seat back also moved to a horizontal position, a large platform area useful e.g., as a bed, is provided. Also concealed storage space below the platforms as well as additional storage space above the platforms are provided in their extended position. The platforms are pivotal into a folded position and retained behind the substantially vertically extending seat back thereby providing substantial storage and cargo carrying space behind the conventional vehicle seat.
