A stroller includes laterally spaced apart hubs that interconnect upper, middle and front frame member assemblies of a chassis of the stroller. The hubs are disposed one each along opposite sides of the stroller, and include mounting structures for coupling two or more of the strollers together in a side-by-side fashion. The hubs further include other mounting structures for mounting a seat assembly to the stroller chassis and for supporting both rearward facing and frontward facing orientation of the seat assembly as well as selectable inclination positions. Each of the hubs includes a folding mechanism for supporting folding of the stroller, such as for transport in a vehicle or for storage. Other laterally spaced apart hubs are provided along the upper frame members for providing a second point of attachment between two coupled strollers and for mounting of accessories.
