The stroller frame includes first and second frame supports spaced apart from each other, at least one third frame support attaching the first frame support to the second frame support, and wheels rotatably attached to one or more of the frame supports. The seat system is removably attached to the stroller frame and includes a seat support having first and second end portions, and first and second end connectors disposed on the corresponding first and second end portions of the seat support. Each end connector includes a connector body having first and second end portions, where each end portion defines a recess configured to receive one of the frame supports. The recesses arranged substantially in opposition to engage the received support in substantially opposing directions.
