Strollers are described that may be used as single strollers or may be reversibly connected together to form a double stroller. Strollers may comprise complementary connectors to be reversibly connected two single strollers in a side-by-side configuration with the rear wheels of the single strollers are interlocked to reduce the overall width of the double stroller. Further, single strollers may comprise complementary connectors to be reversibly connoted two single strollers in a train configuration with the front wheels of the single strollers interlocked to reduce the overall length of the double stroller. Additionally, single strollers may be produced with sets of connectors such that they may connected in either the side-by-side configuration or the train configuration.
