Short Description

Charlie is a high back booster seat designed to support your child’s safety, comfort and independence as they grow. Approved to the latest R129 i-Size standard and suitable from 100–150 cm, it combines intuitive belt guidance, advanced side impact protection and breathable comfort—making everyday travel simple, secure and stress-free.

Designed to grow with your child

Inspired by evolution, Charlie adapts as your child develops—from their first booster seat through to the pre-teen years.

An adjustable headrest and automatic width adjustment ensure the seat grows in height and space, maintaining proper fit and protection at every stage.

Safety: Supporting correct use every time

Correct seat belt positioning is essential for safety in this age group. Charlie is designed with clear, intuitive belt routing that helps guide both parent and child to buckle correctly—every time.

This anti-misuse approach not only reduces common errors but also helps children learn to secure themselves safely and independently.

Key safety features:

• i-Size (R129) approved for enhanced safety standards
• Continuous side protection for head, shoulders and hips
• Side Impact Buddy for additional protection on the window side
• Guided belt routing to support correct positioning

Comfort: Built for longer journeys

Comfort plays a key role in keeping children properly positioned. Charlie’s seat is carefully shaped to distribute pressure evenly, helping reduce discomfort on longer trips.

Multiple ventilation channels combined with breathable fabrics improve airflow, helping regulate temperature and keep your child cool—no matter the journey length.

Ease of use: Encouraging independence

Charlie is designed to make everyday travel easier for both parent and child. The intuitive design allows children to quickly learn how to buckle themselves correctly, supporting independence while maintaining safety.

Lightweight construction also makes it easy to move between vehicles when needed.

Materials: Safe, soft and practical

All fabrics are OEKO-TEX® Standard 100 certified, meaning they are free from harmful substances and safe for sensitive skin.

The removable covers are machine washable, making it easy to keep the seat clean and fresh over years of use.
