- i-SIZE child seat with lasting safety for children from 35 to 12 years (100 – 150 cm)
- Highback booster protection: The highback boosters protect the child in 3 ways: the seat shell provides head to hip protection for the child; the upper and lower belt guides provide correct positioning of the seat belt; and the padded headrest provides safety and comfort for the child’s head and neck.
- Three seats in a row: The seat’s slim and compact design allows for three seats to be installed in the back row of a wide range of cars
- Sustainable quality: 1.3 kg lighter than the previous model, therefore less CO2 emissions during transport; plant-based & recycled packaging
- This child car seat has to be installed using the vehicle’s 3-point seat belt as well as the ISOFIX anchorage points in your car or only with the car’s 3-point seat belt (if there is no ISOFIX in the car).
