The Cosatto Dock I-Size Isofix Car Seat Base is an easy to install adaptor for your Cosatto Dock I-Size 0+ Car Seat that will bring an extra layer of security as well as peace of mind. Most modern cars feature ISOFIX points as standard, and this seat simply plugs straight into them, once you hear the click you know it safe to start the trip. If you have a vehicle without ISOFIX points, we do also stock a belted semi-universal base to be used alongside your 3 point car seat belt. The Dock i-Size base has anti-rotation devices to prevent car seat movement. The rebound bar and support leg provide ultimate stability, and the spring-loaded support leg is designed to fold away underneath, when not in use.
