Britax Römer ADVANSAFIX PRO i-Size Car Seat - Group 1/2/3 Extended Use (15 Months to 12 Years)

Your Child's Faithful Travel Companion for Over a Decade

The Britax Römer ADVANSAFIX PRO i-Size isn't just a car seat - it's your child's faithful friend for every adventure from toddlerhood to adolescence. Designed to grow with your little one, this innovative seat provides ultimate protection from 15 months right up to 12 years, eliminating the need for multiple car seat purchases as your child develops.

i-Size Safety Excellence for Modern Families

Approved to the latest i-Size safety standards (UN R129), the ADVANSAFIX PRO delivers uncompromising protection that exceeds traditional safety requirements. This forward-thinking design prioritises your child's safety whilst offering exceptional versatility and comfort for the entire family.

Effortless FLIP&GROW Technology

Simply convert from a harnessed seat to a highback booster seat in a few easy steps thanks to the ingenious FLIP&GROW function. Once your child reaches 100cm (max. 105 cm / 22 kg), change the integrated 5-point harness to your car's 3-point seat belt easily, ensuring seamless transitions as they grow.

Advanced Safety Technologies

Triple Protection System

The ADVANSAFIX PRO features three advanced safety technologies working in perfect harmony:

SICT (Side Impact Cushion Technology)

Protect your little one in the event of a side collision with superior side impact protection. The Side Impact Cushion Technology (SICT) minimises the distance between the car and the car seat, reducing the force of an impact by up to 40%, directing dangerous forces away from your precious child.

XP-PAD Shock Absorption

Protect your little one's precious neck in a frontal impact with the shock-absorbing foam XP-Pad. In an accident, it reduces an abrupt forward head movement by up to 30%, preventing your child's chin from hitting their chest. The XP-PAD also provides comfortable padding to prevent seat belt irritation.

SecureGuard Frontal Protection

Adding an extra fourth contact point to secure the lap belt safely across your child's pelvis - rather than their delicate tummy - reduces abdominal forces by up to 35%, providing crucial protection during frontal impacts.

Key Features & Benefits

Extended 5-Point Harness Protection

The 5-point harness can be used right up until your little one reaches 105 cm (max. 22 kg), meaning you can rely on the ADVANSAFIX PRO to keep your little one safe for longer. This extended harness use provides superior protection compared to standard Group 1/2/3 seats.

Independent ISOFIX Installation

Install the seat more easily, since each ISOFIX connector of the ADVANSAFIX PRO is operated independently. They're fast and safe to connect, making installation straightforward even for busy parents.

Top Tether Stability

The sturdy Top Tether minimises any rocking movement of the car seat during an accident, reducing the possibility of harm to your child's head and neck, providing additional peace of mind.

EasyRecline Comfort System

Let your little one sleep comfortably throughout childhood travels with the EasyRecline function. Adjust effortlessly even when your child is in the seat, ensuring optimal comfort for naps and long journeys.

V-Shaped Protective Headrest

The V-shaped headrest is specially designed to limit the movement of your child's head, protecting their neck if the worst happens, whilst giving them space as they grow. The headrest and harness adjust simultaneously for perfect positioning.

Soft Performance Chest Pads

Your child's movements are reduced in a collision thanks to the soft performance chest pads. The pads bring even more comfort to the secure 5-point harness, and for those inevitable messy moments, they can even be removed for washing without having to detach the straps.

Why Choose the ADVANSAFIX PRO?

Exceptional Value for Money

It's a great price when you think how long it will actually last you, meaning you could only need two car seats during their childhood. This represents outstanding long-term value compared to purchasing multiple seats.

Space-Efficient Design

The Britax Römer ADVANSAFIX i-Size is quite a slim seat measuring 44cm in width. This is great for people trying to fit three car seats along the back seat for their children.

Superior European Engineering

We are big fans of Britax Römer and the great child car seats that they design and make, all in-house in Germany. Every ADVANSAFIX PRO benefits from decades of German engineering excellence and safety innovation.

Extended Legal Protection

The car seat can be used for longer as a high back booster, up to 150cm, even though the law is up to 135cm. This extension is great and offers protection for the child longer if you choose.

Care & Maintenance

Quick-Remove Cover System

Machine washable cover easily detaches from the car seat without removing the harness, so you can get back on the road quicker. This innovative design saves time and reduces hassle during cleaning.

Care Instructions

  • Remove cover using simple quick-release mechanism
  • Machine wash at 30°C with mild detergent
  • Air dry - do not tumble dry
  • Chest pads can be removed separately for washing
  • Harness remains attached for easy reassembly

Expert Safety Recommendations

Forward-Facing from 15 Months Minimum

We are pleased that the newest version of the ADVANSAFIX, as a forward facing only seat, is suitable from 15 months as a minimum, as rear facing is much safer for younger children. The i-Size regulation ensures optimal safety timing for the transition to forward-facing travel.

Professional Installation Verification

Always verify compatibility with your specific vehicle and consider professional installation checking to ensure optimal safety performance.

Our dogs hurt their mouths chewing these bones
Color: Purple & Blue
I don't do a lot of reviews because I realize many are objective opinions. However, in this case I felt it was necessary to warn others. Our dogs are aggressive chewers. Their last rubber bones (not these) which we've purchased before, and recently purchased again, were destroyed quickly. Chunks of rubber came off the ends. Since those didn't hold up like they used to, I found these harder bones hoping they would last longer. They were able to gnaw into the hard plastic within a few minutes. This created sharp edges that cut their mouths. When I saw a bit of blood on the bones, I took them away from the dogs and threw them away. I wondered why they quit chewing on them after being so excited at first. Also, these are hard enough to damage a tooth.

Pups have shown zero interest in these toys….
Color: Purple & Blue
I would agree that these are indestructible being neither of my dogs have shown any interest in these at all. At this rate they should last forever…
