Britax Römer Advansafix Pro Style
The evolutive car seat for families looking for safety, comfort and many years of use. The Britax Römer Advansafix Pro Style grows with your child from 76 to 150 cm, with a 5-point harness up to 22 kg, ISOFIX, Top Tether, XP-PAD, SecureGuard, SICT and EasyRecline.
What is the Britax Römer Advansafix Pro Style?
The Britax Römer Advansafix Pro Style is an evolutive i-Size car seat designed to cover a very wide stage: from 76 to 150 cm.
It is a practical option for families who want a durable, safe and comfortable child car seat, avoiding frequent changes as the child grows.
Who do we recommend the Advansafix Pro Style for?
For children from 76 to 150 cm
Perfect for covering from around 15 months to approximately 12 years, always respecting the child’s height, weight and maturity.
For families who want a long-lasting seat
It helps avoid buying several seats during growth, keeping one stable and safe solution for years.
For cars with ISOFIX and Top Tether
During the first stage, installation with ISOFIX and Top Tether is recommended for a firm and secure fit.
For daily journeys and long trips
Its EasyRecline, V-shaped headrest and Style fabrics help improve comfort in frequent use.
Opinion from Algateckids specialists
After more than 20 years advising families on child car safety, we consider the Britax Römer Advansafix Pro Style one of the most complete evolutive seats in the 76-150 cm range.
It stands out especially for keeping the 5-point harness up to 22 kg, incorporating XP-PAD, SecureGuard and SICT, and offering a very simple transition to the vehicle seat belt thanks to FLIP&GROW.
Why choose an evolutive seat like the Advansafix Pro Style?
Avoids constant changes
One seat covers a very long stage, from 76 to 150 cm.
Harness for longer
Allows use of the 5-point harness up to 105 cm or 22 kg.
Greater side protection
The SICT system helps absorb energy in the event of a side impact.
Better belt guidance
SecureGuard helps position the lap belt more safely.
Daily comfort
EasyRecline allows the seat to be reclined even with the child seated.
Simple transition
FLIP&GROW makes switching from harness to seat belt easier without complicated disassembly.
Advanced safety at every stage
5-point harness
Up to 105 cm or 22 kg, it distributes restraint forces and keeps the child securely held during the first stage.
XP-PAD
Helps reduce the load on the neck in frontal impacts and improves seat belt comfort.
SecureGuard
Adds a fourth contact point to the lap belt, helping guide it towards the pelvis.
Side SICT
Designed to absorb energy in side impacts before it reaches the child.
A seat designed to grow without losing protection
One of the advantages of the Advansafix Pro Style is that it is not simply a “large” car seat. It is designed to adapt to different stages while maintaining specific protection systems for each growth phase.
During the first stage, the child travels with a 5-point harness. Later, the seat helps ensure correct use of the vehicle seat belt with features such as XP-PAD and SecureGuard.
How it is installed according to each stage
From 76 to 105 cm
Recommended installation with ISOFIX + Top Tether. The child uses the 5-point harness up to 105 cm or 22 kg.
From 100 cm
It can be used with the vehicle’s 3-point seat belt, combined with ISOFIX if the car allows it.
Up to 150 cm
Works as a high-back booster, correctly guiding the belt until the end of the child restraint stage.
