Highlights

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.

Features:

The Britax Römer Pivot Link ISOFIX System

In case of an impact, our patented Pivot Link ISOFIX System directs the force first downward (1), into the vehicle seat, and then forward (2), more gently – greatly reducing the risk of head and neck injury for your child.

5-point harness

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.

Soft neoprene performance chest pads

Our new, soft neoprene performance chest pads fit comfortably on your child’s chest. They help reduce your child’s movement in the event of a collision, and add even greater comfort to the 5-point harness. Plus, they can be easily removed for washing without disturbing the harness.

Unique protection for the neck and chest

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.

SecureGuard

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.

Advanced Side Impact Protection – SICT

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.

Highback booster protection

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.

V-shaped headrest

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.

Top Tether

The Top Tether minimises the rotation of the car seat and thus reduces possible injuries in the head and neck area in the event of a collision. Due to its twin anchorage points, the v-shaped Top Tether offers even greater stability and security for your child than a seat with conventional tethers.

EasyRecline

EasyRecline is suitable for all ages and allows you to adjust the seat into comfortable recline positions, even when your child is in the seat and without having to re-adjust the Top Tether — total convenience for both the parent and the child.

Flip & Grow

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.

Quick-remove cover

Things can get pretty messy on the road. Drinks can spill and children can get car sick. That’s why we designed a machine washable seat cover that can easily be taken off without removing the harness, so you can clean up quick and get on your way.
