48-144 months

These seats are designed for children in the group 2/3 stage, roughly from 4 to 12 years old, approved by height under the i-Size (R129) standard. The exact height range is shown on each product's page. Your child should keep using the seat until the seat belt no longer fits correctly across the shoulder and hip without riding up.

A seat with a backrest gives better shoulder belt positioning, side head support and greater protection in a side impact, unlike a backless booster. That's why we recommend choosing a model with a backrest for as long as your child benefits from it, always following the manufacturer's height limits.

On the group 2/3 models in this collection, your child is always secured by the car's 3-point seat belt. The ISOFIX connectors, where fitted, secure the seat to the car seat and increase stability, but do not replace the seat belt. Check the manufacturer's manual and confirm compatibility with your car before fitting.

AirLayer liners were designed to improve airflow and comfort, reducing sweating on journeys. They're suitable for group 2/3 car seats, but compatibility depends on the model. Check on the product page and in the manufacturer's instructions whether the liner suits your car seat, without altering the path of the seat belt.

Benbat support cushions help hold the child's head while they sleep on journeys. They should be positioned so they don't interfere with the belt's path or the child's correct positioning. It's recommended to follow the manufacturer's age and usage guidance, and always check that the belt is still properly adjusted.

This collection brings together items designed for children from 4 years old, such as car comfort covers and accessories, travel cushions, sheets and educational toys. Each product states the recommended age on its page; if you're unsure whether something is suitable for your child's age, the Bonabebe team can help.
