Child Car Seats 15 kg - 36 kg

Buy child car seats suitable from 15 - 36 kg online on

As soon as your child weighs 15 kg or more (approximately 3 to 4 years of age), you will have to move on to a child car seat of the next higher category – group 2/3. A child car seat from this group is suitable until your child reaches a weight of 36 kg or an age of 12 years.

The biggest change in the transition to a group 2/ 3 child car seat is that your child can now travel in a forward-facing mode if you have previously used a rear-facing child safety seat. 5-point harness or impact shield is now to be replaced by your car's 3-point safety belt.

Most group 2/3 child car seat models consist of a padded booster seat, a height-adjustable backrest and headrest, and head and shoulder protectors that ensure maximum safety in the event of an accident. They are usually quite light in weight which comes in particularly handy if you need to transfer the child car seat from one vehicle to another more often. Some also feature armrests or are adjustable in width – that way, additional comfort is provided and even older children feel good when riding in the car.

Your little passenger is secured with the vehicle's own 3-point belt. For this purpose, the child car seats have mounting brackets on the backrest or so-called belt positioners, which allow a precise position of the belt. This is particularly important because the 3-point harness in the car is set to the size of an adult and is thus far too high for a child. With the help of the mounting brackets or belt positioner, the belt is positioned correctly and prevents injuries on the neck.

Despite their relatively long service life of about 8 years, child car seats from group 2/3 are among the lower-priced car seats, which cost on average between about 100 € and 350 €. Nevertheless, there are even cheaper but also much more expensive models on the market. Although the price is important when choosing a new child car seat, it does not imply anything about the safety of a car seat. All child car seats offered on the market must first undergo tests to see whether they correspond to the safety standards ECE R44 / 04 or UN R129 i-size. It is more important to choose a child car seat that suits you, your car and of course your child best.

How to install a group 2/3 child car seat in the car?

When you buy a child car seat, you should first check if it is suitable for your child's age group. The next step is to make sure that the car seat fits your car type. Not all child car seats are compatible with all types of vehicles. Some do not fit properly in the car, so they restrict your child’s legroom or make it difficult for you to secure the seat and your child with the 3-point harness. Therefore, it is important to check beforehand if the car seat you prefer can be installed correctly in your car. Most manufacturers offer a quick online verification service, such as the Britax Römer Fit Finder®.

The vast majority of group 2/3 child car seats offered in our store are to be installed by using Isofix. Some of these child safety seats have retractable Isofix hooks so they can be also used in combination with the car's 3-point safety belt. Other models do not feature Isofix and can be used in cars that do not yet have Isofix anchor points.

Things you need to consider when buying a child car seat from 15 to 36 kg

When buying a new child car seat from the next higher category, you should ask yourself what qualities and features you prefer most. Therefore, you might find it helpful to stick to the following questions:

  • Installation: Is the child car seat fastened with the safety belt or via ISOFIX?
  • Handling: How easy is it to secure the child car seat and your child in the car?
  • Adjustability: Can you adjust the height of the backrest and/ or headrest so that your child can travel comfortably in any stage of growth?
  • Side impact protection: Does the child car seat provide additional protection for your child in the event of a side impact?
  • Removable covers: Is it important for you to be able to remove and wash the covers in the event of a little accident?
