Britax Romer Dualfix M Plus 360 Spin Car Seat

The BubsNest Verdict

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.

BubsNest expert analysis of 5 parenting forum discussions

“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.

Best for

  • Families seeking a high-quality, long-lasting car seat with excellent safety features
  • Parents who value the convenience of a 360-degree swivel seat

May not suit

  • Families with limited boot space or narrow car access points
  • Budgets-conscious shoppers looking for a more affordable i-Size option

Tips from parents

Before You Buy

Check the Dualfix's dimensions and your car's compatibility to ensure it will fit comfortably

Shopping Tip

Look for sales or bundle deals to offset the premium price tag

Getting the Most Out of It

Take advantage of the 360-degree swivel to make getting children in and out easier
