Britax Römer Dualfix review

Product alert

The Britax DualFix car seat has passed the regulatory tests required by the ECE R44/04 standard to be sold as suitable for children from birth to when they weigh 18kg, and in our own more rigorous tests it achieved a good overall safety rating. However, the harness on the DualFix could not be secured tightly enough on our newborn test dummy - there was too much slack and our experts believe there is a small risk that a wriggly newborn could free themselves from the shoulder straps of the harness. For a safety issue like this we limit the total score overall to 20%, and the score drops below our Don't Buy threshold of 45%.

We've tested the latest version of the Dualfix, the Britax Römer DualFix i-Size. Click on the link to read more on how it performed.

The Britax DualFix car seat is an Isofix-only Group 0+ and Group 1 car seat suitable to be used from birth up until your child weighs around 18kg (four years old). It features a unique 360-degree rotation, which makes getting your child into the seat and changing from rearward- to forward-facing simple. Our safety alert reveals why we've had to downgrade this seat to a Don't Buy. An updated version of the DualFix is due out Summer 2019. In the mean time, we've recently tested the i-Size version, the Britax DualFix i-Size.
