An opening is formed in the rear wall of the one tier, and a storable seating unit is movable between a stored position and a deployed position through the opening. The seating unit is supported by the horizontal surface of the one tier, and is configurable in a storable configuration and a deployed configuration. The seating unit height is greater when in the deployed position than in the storable configuration. The opening height is less than the height of the storable seating in the deployed configuration, and greater than the height of the storable seating in the storable configuration.
