A seat unit (4) for use in a stepped seating venue comprises a rear frame (11) having a fixed back support (17), a fold away seat pan (21) pivotally mounted with respect to the rear frame (11) on a pair of seat pan pivots (23) and forward of the rear frame (11) when in use. The seat pan (21) folds against the rear frame (11) when not in use. A second frame (25) to support feet is also pivotally mounted on frame (11) below the seat pan pivots (23). The second frame (25) moves in tandem with the seat pan (21) from an open position substantially parallel to the seat pan (21) when the seat pan is in use to a position against the rear frame (11) when the seat pan (21) is not in use.
