How to choose?
When choosing a car seat for children 40–105 cm (group 0+/1), consider:
- Rear-facing travel: The i-Size standard requires rear-facing travel at least until 15 months, which increases protection of the head, neck and spine.
- Side impact protection: Advanced side protection reduces the risk of injury in side collisions.
- ISOFIX installation: ISOFIX reduces the risk of incorrect installation compared with fitting the seat with the vehicle belt.
- A seat that grows: An adjustable headrest, several recline positions and adjustable harnesses let the seat accompany your child through different stages.

More about Car seats 40–105 cm (group 0+/1)
Car seats 40–105 cm (i-Size) take your child from birth or from about 15 months up to 4 years. Most are reboarders and 360° rotating Isofix seats that allow extended rear-facing travel – which safety experts consider the safest way to carry young children.
40–105 cm car seat FAQ
What is the difference between a reboarder and a 360° rotating seat?
A reboarder lets your child ride rear-facing. A 360° rotating seat is a reboarder that swivels towards the door, making it easier to seat and buckle your child; some models can also face forward after 15 months. KikkaBoo 360° car seats compared →
Does my child have enough legroom when rear-facing?
Yes – children bend their legs or rest them on the vehicle seat back without discomfort. Leg injuries in rear-facing seats are rare and far less serious than neck injuries when facing forward. Why rear-facing is safer →
Will the seat fit my car?
Check the manufacturer's vehicle fitting list. Seats with a support leg need a solid floor – some cars have an under-floor storage box where a support leg must not rest. Try the installation before you buy.
When should we move to a 100–150 cm seat?
When your child exceeds 105 cm or the top of the head is above the headrest at its highest setting – usually around age 4. From then on the car's seat belt secures the child. Car seats 100–150 cm →
