For this age the Be Safe iZi Modular consist of one ISOfix compatible base and child seats which conform to the new EU standard R-129 (i-Size). The iZi Modular RF i-Size can be used rear facing only. The base module can be extended to allow more legroom for the child, which means children up to the age of about four years (105 cm tall) can be transported rearfacing. The Be Safe iZi Modular RF i-Size can easily be installed on the iZi Modular i-Size base. Just click the seat onto the base and you are ready to go. The iZi Modular can be used rear facing only. The iZi Modular RF i-Size adapts to your growing child with the adjustable headrest and the bodyhugger. The easy magnets keep the harness out of the way when they are not in use. The very good sleeping positions make this the perfect choice. The Be Safe iZi Modular RF i-Size performs very well in crash tests
