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.

The Tale of Salem
Format: Paperback
If you’re not familiar with the history of Salem and its witch trials, this graphic novel is a solid entry point. The author, while not a historian, clearly put in the work—spending time in Salem, connecting with residents, and striving to honor both the historical record and the modern-day sentiments of those who live with that legacy. His goal was to get the facts right while also capturing how the people of Salem view their own history, and I think he succeeded in that respect. The artwork fits the subject matter well. We often imagine people of that time as living hard, joyless lives, and the art conveys that sense of austerity. The mix of black-and-white and color panels is sometimes striking—there are moments where the color really enhances the impact of a scene—but other times I wasn’t sure what it added. Still, the black-and-white aesthetic ties neatly into the grim tone of the era. That said, the book is quite long, and if you’re already well-versed in the Salem Witch Trials, you may not learn much new in terms of facts. But if you enjoy studying the trials or want to explore the story through a different medium, this graphic novel is definitely worth picking up. For me, it landed at a 3.5 stars, which I’ll round up to 4 (since I usually do that when posting on review sites).

Salem's a Lot
Format: Paperback
Great comic that deserves to be at the top end of best of 2025 lists. Intensively researched with multiple art approaches to the varied settings. It also made me want to take a trip to Salem in the off-season. A virtuosic undertaking!

Offers the bloody, beating heart of the Salem Witch Trials
Format: Paperback
Unlike so many books and movies that examine the Salem Witch Trials from an academic or outsider perspective, "More Weight" plunges you into the everyday life of 1692 Salem. Giles Corey's story is often boiled down to the story of his death but he and Martha are given a deeper look here, with the result of some truly disturbing pages. The addition of Hawthorne and Longfellow sharing their thoughts in 1860 and then a look at what Salem is today, further enriches an already multi-layered story. Incredible work.
