A seat assembly includes a mounting plate and a base frame rotatable mounted on the mounting plate by a swivel mechanism for swiveling the seat assembly between forward-facing and rearward-facing configurations. A seat portion is operably coupled to the base frame and includes a front edge. The seat portion can be pivoted between use and upright non-use positions. The seat assembly includes a first rotational footprint when the seat portion is in the use position and a second rotational footprint that is less than the first rotational footprint when the seat portion is in the upright non-use position. The second rotational footprint is intended to accommodate swiveling of the seat assembly between the forward-facing and rearward-facing configurations within a vehicle interior.
