The Britax Max-Fix is an extended rearward-facing child car seat for children up to four years old. This can protect them from more severe head and neck injuries in a crash. Extended rear-facing child car seats can be a bit uncomfortable on a child's legs, so how does the Max-Fix compare? We sent it to our lab for crash testing to find out.
This is a satisfactory child car seat, but as with other rear-facing seats the mediocre leg support and view from the seat let it down a bit. It provides good protection in a front-impact crash but its side-impact protection is only rated as satisfactory, not high enough to make it a Best Buy.
What is it?
A Group 0+/1 child car seat for children from 9-18kg (nine months to approximately four years old).
The child is restrained by a five-point harness with a one-pull adjustment strap to make it easy to tighten.
It's an extended rearward-facing seat, that's installed using the car's Isofix points and two support legs, one to position it on the car seat correctly and another that braces the child seat against the floor and prevents it pivoting in a crash.
The support leg may make this seat unsuitable for use in some cars that have underfloor storage compartments or limited back-seat leg space.
How safe is it?
The harness sits in the right place on your child, the head support is excellent and the Max-Fix sits firmly on the car's seat.
In our crash tests front-impact protection is good but the side-crash protection is only average.
Is it easy to fit the seat?
The instructions and warning labels are very easy to understand and there is little danger of installing the Max-Fix incorrectly.
But the seat is very heavy and takes up a fair bit of space in the back seat.
Is the seat comfortable?
Yes and no; the seat has excellent padding, is spacious and creates a good seating position for comfort and safety for the child.
However, the leg support is uncomfortable, particularly for older children and the child's view out of the car is limited.
Is there anything else I should know?
The finish quality of the seat is excellent and the covers are easy to remove and machine washable.
In 2011, we changed the car body we use for testing to more accurately reflect the current typical family car seat belt layout and design. We carried out some repeat testing to ensure that previous tests shown online are broadly comparable with the current ones. However, such a significant change means we can't make absolute comparisons.
These results are from our 2013 tests.
Should I buy it?
As with all rear-facing seats there are some issues with comfort for your child. Crash protection is reasonable but not as good as our Best Buys.
Pros: Good front-crash protection, good harness position and head support, easy to install, spacious seat with good padding, easy to clean
Cons: Average side-impact protection, some comfort issues. Pricey
