A cup holder for beverage containers has a deployable tray movable between a deployed position and a stowed position. The tray has an upper surface, a lower surface, and an aperture. A cup insert includes a cup ring, a cup bag, and a coil spring. The cup ring has an open collar for receiving a beverage container and has a seating flange configured to rest on the upper surface. The cup bag is made of flexible material having a generally cylindrical shape between an upper rim and a bag bottom. The upper rim is affixed to the open collar. A coil spring is coupled between the cup ring and the bottom end for urging them together for collapsing the cup bag. The coil spring is expandable under the weight of a beverage container placed on the bag bottom.
