A stroller includes a front frame member assembly supporting laterally spaced apart front wheels, a middle frame member assembly supporting laterally spaced apart rear wheels; laterally spaced apart hubs interconnecting the frame member assemblies, and a seat assembly. The hubs each have a mounting structure that comprises a shaft extending from the respective hub. The shafts are axially aligned one with the other, each having two parallel flat sides and two curved sides joining the flat sides. The seat assembly comprises at least one seat frame member, and connector assemblies disposed on opposite sides of the seat frame member. Each connector assembly comprises a mounting surface having a recessed slot defined therein, each slot having a narrow portion disposed between two relatively wider portions. The narrow portion corresponds approximately to the distance between the flat sides.
