Britax Römer Advansafix III SICT Car Seat Review

GROUP 1/2/3


Reviewed by Emma Stubbs

I was very excited to be given the opportunity to review one of Britax’s latest car seats. Knowing Britax’s reputation for car seat safety, I have always used their car seats for my little girl, and she was soon about to outgrow her Britax Dualfix group 0+/1 seat.

The Britax Römer Advansafix III SICT is a multi-stage, group 1/2/3 car seat. This means it is suitable from 9kg all the way to 36kg (roughly 9 months to 12 years), which is rather impressive. The way the seat transitions from baby/toddler seat with a 5-point harness to a high back booster seat is very clever, and makes it extremely cost-effective.

Installation was fairly straightforward – there are a lot of diagrams and instructions to follow, and after searching on the internet, it was clear that a lot of people used the clear instructions of YouTube videos to make sense of how to fit the seat safely. However, my husband didn’t seem to have much trouble (and he’s the type who swears a bucket-load whilst doing a simple DIY task). The Advansafix uses a top tether strap that connects to the boot in addition to the ISOFIX points, which I had never seen before – put simply it is added protection so that the entire car seat is fixed to the body of the car and not just the base. I loved the green indicators that showed that both the ISOFIX points and the top tether were fitted correctly and tightly.

The only slight issue we had was that when the car seat was installed, the seat would not recline. I was immediately gutted, as this was one of the main selling points for me – my daughter loves to nap in the car and knowing that the recline feature was an option for all ages and stages was a real bonus. There was no mention of the recline feature in the instruction manual, however, it transpired we just needed to loosen and refit the top tether slightly to allow the recline to work.

I really loved how easy it was to adjust the height of the shoulder straps and head rest without having to take the straps out – the mechanism is simple to operate with one hand.

Safety-wise, this car seat feels a lot safer and secure than any other car seat I have used. It is very sturdy with no wobble whatsoever, and the headrest is well-cushioned around side-wings that would protect the head on any impact. There is also SICT technology included, which is a pod that comes in a separate box that fits into the side of the seat. This distributes the force of an accident away from your child.

Another feature that stands out is the removable cover. To remove the cover, you don’t have to remove the straps, so food spills, toddler accidents and car sick incidents are easy to deal with. There is also a summer cover available, which I may purchase separately.

In her first trial journey, and in further subsequent journeys, my 2-year-old daughter was happy and comfortable. I am confident that when she is older and uses the normal seat belt instead of the 5 point harness, she will be able to safely use the red reference points to know where to put the belt correctly.

There is one major drawback of the Advansafix III, and that is the fact it is completely forward facing with no option for rear-facing. There has been much research and advertising to try and make more parents aware of the benefits of children being rear-facing for as long as possible, and this seat doesn’t give parents that opportunity. For this reason, I feel I cannot give it the maximum rating, but I cannot fault this fabulous car seat in any other way.

Rating: 4/5

RRP: £250
