A power riser assembly riser assembly includes a rear leg pivotally coupled between a seat assembly and a vehicle floor defining upper and lower axes. A drive linkage is operatively coupled between the seat assembly and floor. A drive mechanism coupled to the drive linkage actuates in a first direction causing the drive linkage to pivot the seat assembly about the lower axis from a seating position to an intermediate position whereat the drive linkage transfers pivotal movement of the seat assembly to the upper axis, thereby moving the seat assembly to the stowed position. The drive mechanism actuates in a second direction causing the drive linkage to pivot the seat assembly about the upper axis from the stowed position to the intermediate position whereat the drive linkage transfers pivotal movement of the seat assembly to the lower axis, thereby moving the seat assembly to the seating position.
