✅ The last car seat your child will need, from 3.5 to 12 years old
✅ Secure installation with ISOFIX or seat belt
✅ Developed with the highest European safety standards
✅ Advanced protection against frontal and side impacts
✅ Comfortable even on long journeys
✅ Compact design ideal for families with more than one child
The Kidfix i-Size from Britax Römer was developed with what matters most in mind: your child's safety and comfort, combined with parents' peace of mind. This is, most likely, the last car seat you will need to buy.
Compatible with the i-Size system and approved according to the latest European standard UN R129, it accompanies the child's growth from 100 to 150 cm in height — that is, from approximately 3.5 years old to 12 years old.
It is an excellent choice for those looking for a safe, comfortable, and durable car seat that grows with your child and adapts to different cars, with simple installation via ISOFIX.

Additionally, the headrest is height-adjustable, allowing the seat to accompany the child's growth, always ensuring adequate support.
The Britax Römer Kidfix i-Size Car Seat includes a redesigned and more ergonomic base, with soft foam and comfortable back support, for longer journeys without complaints. The structure was designed to allow air circulation, helping to regulate temperature and preventing your child from getting too hot during travels. The backrest with automatic recline easily adapts to the car seat, offering a more natural and relaxed position.
Installation is simple and quick: it can be done with ISOFIX for greater safety and stability, or only with the seat belt if your car is not compatible. And, thanks to its compact design (only 44 cm wide), it is possible to install up to three Kidfix i-Size seats side-by-side, ideal for families with more than one child.
This car seat includes three exclusive Britax Römer safety systems:
- XP-PAD – Absorbs up to 30% of the force in frontal impacts, reducing the risk of neck injuries.
- SecureGuard – A fourth seatbelt attachment point that helps keep the belt in the ideal position over the pelvic area, reducing the risk of abdominal injuries.
- Adjustable SICT – Extra side protection that reduces impact forces by up to 40% in side collisions.
Installation with Isofix or seat belt
The Britax Römer Kidfix i-Size offers two installation options:
- Isofix and three-point belt
- Vehicle's three-point belt
Product specifications
With a width of 44 cm (without SICT), it is possible to place three seats in the back seats of many cars, especially those equipped with i-Size seats or with ISOFIX in all three seats.
