A shopping cart has a forward end and an aft end and includes a base structure including wheels, a chassis supported on the wheels, and a basket attached to the chassis. The shopping cart also includes an accessory seat structure attached in articulated fashion to the base structure and including a seat base and at least one leg attached to the seat base. The seat base has a forward end and an aft end. The accessory seat structure is movable relative to the base structure between a stored position, in which the forward end of the seat base is positioned beneath the basket, and a deployed position, in which the seat base extends aft of the basket and is supported in a substantially horizontal orientation by the base structure at the forward end of the seat base and by the leg at the aft end of the seat base.
