A seat assembly for supporting an occupant above a floor includes a support mechanism operatively coupled between a seat back and a seat cushion. A rear end of the seat cushion is released from the support mechanism to pivot the seat cushion from a generally horizontal position to a generally vertical position in response to pivotal movement of the seat back from an upright seating position to a forwardly folded position. The support mechanism is released from the floor and a stand-up link pivotally coupled between the floor and the support mechanism moves the seat cushion from the generally horizontal position to the generally vertical position and simultaneously urges the seat back to pivot relative to the seat cushion, thereby maintaining the seat back in a generally vertical orientation defining a stand-up position.
