Advice

How to choose?

When choosing a car seat for children from 40 to 105 cm (group 0+/1), consider:

  • Rear-facing travel: The i-Size standard requires rear-facing travel at least until 15 months of age, which increases protection for the head, neck, and spine.
  • Side protection: Advanced side protection reduces the risk of injury in side-impact collisions.
  • ISOFIX installation: The ISOFIX system reduces the possibility of incorrect installation compared to securing the seat with the vehicle's seatbelt.
  • Growing seat: An adjustable headrest, multiple recline positions, and adaptable harnesses allow the seat to accompany the child through different developmental stages.
FAQ

What you want to know

Until what age must a child travel rear-facing?
For i-Size car seats 40–105 cm (group 0+/1), rear-facing travel is mandatory at least until 15 months of age, and many models allow this for even longer.
What does the i-Size label mean?
I-Size is a European safety standard for car seats based on the child's height rather than weight, and it prescribes stricter requirements for side protection and ISOFIX installation.
Do I need a special IsoFix base for this car seat?
Some models have the ISOFIX system already built into the seat, while others attach to a separate IsoFix modular base - check the specification of your chosen model.
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 →
