Flexibility that grows with you. With the ADVANSAFIX IV M, the seat now grows even more comfortably with your child. Thanks to the FLIP&GROW function, you can switch from the integrated harness system to the 3-point vehicle belt in just three simple steps when your child reaches 15 or 18 kg. Nothing needs to be removed from the seat, so there's nothing to lose, and it can be converted back at any time. The soft padding and EasyRecline with three adjustable seating positions - for both small and large - ensure that your child is comfortable on every journey.
