A stroller system including an expandable base and two frame members is discussed. The stroller system is configured for dual occupancy and provides an expandable cargo area to a user. The first and second seats coupled to their respective frame members may be modular in nature. The second seat may also include a bench seat with optional secondary support structures. The two frame members are configured to fold independently of one another. The mechanical apparatus of the dual occupancy stroller including locking and actuator mechanisms are discussed. Additionally, the mechanism by which the front frame member folds is discussed. The disclosed stroller is capable of simultaneously carrying multiple children with a cargo area that can be extended or retracted and can carry a heavy load. The stroller is able to easily fold to a stowed state.
