“Praised for superior safety and comfort, but bulky and pricey”

7.8

Solid Choice

The Britax Römer Dualfix 5Z is a well-regarded car seat that offers excellent safety and comfort features. Parents highlight its 360-degree swivel, extended rear-facing capabilities, and high-quality construction. However, some find it quite large and heavy, and note the premium price tag compared to similar i-Size seats. Overall, it seems a solid choice for families seeking a safe, versatile car seat, though the bulk and cost may be drawbacks for some.

What parents love

Safety and protectionParents praise the Dualfix's superior safety credentials, including its i-Size certification, integrated ISOFIX base, and optimised side impact protection.

Comfort and adjustabilityThe seat is described as very comfortable, with 12 recline positions, a newborn insert, and a smooth 360-degree swivel that makes it easy to get children in and out.

LongevityThe Dualfix can be used rear-facing up to 105cm (around 4 years), allowing extended rear-facing for added safety.

Worth knowing

Size and weightSeveral parents note the Dualfix is quite large and heavy, which can make it difficult to move between vehicles or fit in smaller cars.

CostAt £430 RRP, the Dualfix is one of the more expensive i-Size car seats on the market, pricing it out of reach for some families.

Swapping between carsA few parents report that the Dualfix is not the easiest to move between vehicles, as the integrated ISOFIX base is not always compatible with different car models.
