How to choose the right child car seat

When you buy a child car seat, there are a number of criteria you have to check off your list. Size, fitting options and direction are important for your child’s safety and should therefore be deciding factors in your choice of seat. However, quality, where the seat can be used and size adjustment options shouldn’t be underestimated either. We’ll help you narrow down your choice.
Let’s take a closer look at the three most important criteria
1. Child car seat size: baby car seat, child car seat or booster seat
First of all, you want to work out the right seat size for your little one. This depends on the size and weight of your child. Remember that the seat is only guaranteed to be safe if it is the right size. The TCS guide should give you more detailed information (in German). But in general, the following applies:
- Group 0 / 0+ (Birth to 18 months and 13 kg)
- Group 1 (9 months to 3.5 years and 9 to 18 kg)
- Group 2 – 3 (4 to 12 years and 15 to 36 kg)
- Booster seats (4 to 12 years and 15 to 36 kg)
2. Fitting options: Isofix, top tether or seat belt
If you want to attach a child seat with Isofix, you have to make sure your car comes with this function. As of 2014, it became regulation for all cars to have an Isofix system as standard. In older cars without Isofix, you can secure the seat with a seatbelt, also known as a three-point seat belt. There is the risk of you not attaching the seat belt properly. It might not be firm enough or it could be twisted. Nevertheless, this method is flexible and can be used in every car. In comparison, the child car seat with Isofix is quick and easy to fit, and most importantly, you know it’s always attached properly. This means there’s a secure and stable connection between the child car seat and the car. With the help of the right base, the car seat can be permanently attached. An additional support leg or top tether increases stability and restricts the amount of forward movement, meaning your child is always safe.
3. Direction: facing backwards or forwards
Depending on the ECE group and fitting method, child car seats can either be attached facing or in the opposite direction of travel. Rearward-facing systems are safer for infants up to 18 months. In the event of a head-on collision, they support the head, neck and back better than forward-facing seats. For safety reasons, baby seats always have to be forward-facing. Make sure to deactivate the airbag if the baby is in the passenger seat. Child car seats for Group 1 and 2 are available in both versions. Those for Group 3 can only be fitted forward-facing.
