15-48 months

Yes. Models such as the Britax Römer Trifix 2 i-Size are approved under the R129 (i-Size) regulation, the most recent for car seats in Europe. This regulation places particular emphasis on side protection and selecting the seat by the child's height. The specific approval is given on each product's page.

This selection is designed mainly for the 15 months to 4 years stage, roughly. The right choice, however, is based on your child's height and weight, not just their age. It's recommended to check the exact ranges shown on each seat's sheet before buying.

The car seats in this collection use Isofix fitting, often with a load leg or a top tether for extra stability. It's recommended to check the manufacturer's compatibility list to confirm whether the seat suits your car. Correct installation is essential for safety.

Models such as the Trifix 2 i-Size are used forward-facing from 15 months, once your child meets the age and development requirements. We recommend keeping your child rear-facing for as long as possible in the earlier stages. Always follow the manufacturer's instructions regarding the direction of installation.

Both are Britax Römer car seats for this age range, but they differ in the installation system and usage details. The Trifix 2 i-Size is based on i-Size approval and Isofix fitting; the King Pro has its own fitting and adjustment features. It's recommended to compare the two models' product pages and, if in doubt, contact the Bonabebe team.

It's recommended to check the headrest height and harness tension regularly, keeping up with your child's growth. The straps should fit snugly to the body, with no slack, and at the correct shoulder level. The manufacturer's instructions show how to make these adjustments safely.
