Maximum safety – every day
Your child’s safety is of the utmost importance to us. That’s why the new ADVANSAFIX i-SIZE has been developed and approved to the new i-Size standard (R129), and is also equipped with advanced safety features such as the XP-PAD, SecureGuard and SICT all of which provide the best possible protection in any type of accident. Furthermore, your child can benefit from the safety of the 5-point harness for longer as the seat has been designed for usage with harness up until 21kg.
Extra comfort & flexibility – for every family
The ADVANSAFIX i-SIZE offers maximum comfort for your child, together with complete flexibility. Thanks to the FLIP&GROW function, you can easily change from the integrated 5-point harness to the car’s 3-point seat belt as your child moves to the next stage. And because no parts have to be removed from the seat when changing stages, the seat can also be converted back at any time.
Quality – Made in Germany
To guarantee the highest quality possible, we keep the whole product development process under one roof, from the initial idea right up to the finished product. Plus, our car seats are regularly tested in our in-house, state-of-the-art crash test facility at Britax Römer Germany.
We believe a 5-point harness is the safest way to secure your child in a car seat because it keeps your child safe and tight in the seat’s protective shell. In the event of a collision, the harness distributes the forces of the impact across 5 points, two at the shoulders, two at the hips and one where the harness buckles between the legs. This helps to protect your child from all directions of impact.
Despite good planning and careful driving, you can never prepare for a collision. To protect your child's sensitive neck area in case of a frontal impact, Britax Römer has developed a shock-absorbing foam pad. It prevents the impact of your child's chin on their chest, absorbing up to 30% * of the energy. A jerky forward head movement is reduced and the neck is protected. At the same time it provides additional padding around the edges of the seat belt.

The SecureGuard helps to protect your child’s delicate abdominal area by adding an extra – a 4th – contact point to the 3-point seat belt. By keeping the lap belt in an optimal position over your child’s pelvic bones SecureGuard helps reduce abdominal forces in the event of a frontal collision by up to 35 %*, and at the same time allows your child freedom of movement during the journey.

Our SICT offers superior protection to your child in the event of a side collision. It reduces impact forces by minimising the distance between the car and the car seat and deforms to absorb the energy before it reaches your little one. To benefit from the protection, simply adjust the SICT on the side of the car seat closest to the door.
Our highback boosters protect your child in 3 ways: the seat shell provides head to hip protection for your child, especially in the event of a side impact; the upper and lower belt guides provide correct positioning of the seat belt; and the padded headrest provides safety and comfort for your child’s head and neck.
Specially designed to control the movement of your child’s head, our V-shaped headrest ensures optimal protection in the event of a side collision while providing ultimate comfort at the same time. Plus, the headrest and harness can easily be adjusted from the front of the seat to suit your child’s height.
When your child reaches 15 kg and up to a maximum of 21 kg, you must change from the integrated 5-point harness to the car’s 3-point seat belt to secure your child in the seat. Thanks to the FLIP&GROW function, that’s now possible in a few simple steps. Simply adjust the headrest and stow the harness in the backrest so it won’t get lost. Then, switch the FLIP&GROW adjustment plate so the SecureGuard is above the seat and you’re ready to go.
ISOFIX with Top Tether (76 – 102 cm)
This child car seat needs to be attached to the ISOFIX anchorage points of your vehicle. ISOFIX is a standard system of connection points featured in almost all cars. This establishes a secure and firm connection between the child’s car seat and the car. ADVANSAFIX i-SIZE specific requirements – a safe installation is completed with the use of Top Tether to allow optimum stability. Our i-Size car seats will fit all i-Size approved seating positions, so please check your vehicle owner's manual for i-Size approved seating positions.
Belted with ISOFIX attachment (100 – 150 cm)
This child car seat has to be installed using the vehicle’s 3-point seat belt as well as the ISOFIX anchorage points in your car. This ensures a firm and secure connection between the child car seat and car, even when your child is not sitting in it. Check our vehicle list or FIT FINDER® on the product page to see if the car seat is compatible with your car.
Belted (100 – 150 cm)
This child car seat can be installed with the car's 3-point seat belt. This option is handy if you will be transferring the car seat to different cars which may not all have ISOFIX anchorage points. Seat belt guides on the car seat will help you install the seat correctly. Check the vehicle owner's manual for suitable seating positions and ask your local retailer for a test installation in your car (please ask for a member of staff trained by Britax Römer), before you buy the car seat.
