The Car Seat Adapter makes it easy to roll from car to wagon without missing a beat. Designed to snap securely into place on our Pathfinder™4-Seat Stroller Wagons, it’s compatible with more leading infant car seats – giving families added flexibility from day one. It arrives fully assembled and folds flat for easy storage. Whether you’re heading to the park, the farmers market, or just around the block, it brings your littlest rider along for the ride.
