The Car Seat Adaptor is the easiest way to turn your stroller into a customised travel system. Attaching your car seat to a Baby Jogger stroller is extremely easy, and you can even fold the stroller with the adapter attached to give you a hugely versatile travel system. Designed to fit the popular Maxi-Cosi CabrioFix and Maxi-Cosi Pebble car seats, these adaptors fit the City Mini, City Elite, and Summit single strollers.
