Review: Excellent car seat - Excellent quality car seat. Very comfy, and has an easy to use seat belt securing clip. My granddaughter loves it, regularly falls asleep in it during long journeys. Currently fitted in an Audi Q4 with no problems at all.
Review: Good - Bought for 3 year old, using the Isofix attachments, easy to fit and adjust to size. I find it a bit fiddly to actually buckle the seat belt( VOLVO XC60). But once done it’s very secure. The toddler loves sitting facing forward in it. Very easy to change between cars.

## Features

- 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).
