Why should I choose the Britax DualFix i-Size Car Seat?

The Britax Dualfix i-Size Car Seat is suitable from birth to 4 years (105 cm).

During the first four years of your child's life, they grow approximately 52 cm. That means that they will have outgrown 8 clothing sizes by the time they turn four! That’s a huge amount of growth! The Dualfix i-Size provides constant comfort during this period of time. This clever car seat offers 12 recline positions (forward and rearward facing), including an ergonomically flat lying position for a newborn. There is also extended leg space for your "big" little one so that they are not all scrunched up and moaning about being uncomfortable on a long journey. Yes, Britax think about parents too!

How safe is the Britax DualFix i-Size Car Seat?

Your child's safety is our top priority. That's why there are no compromises. Britax’s internal standards are more demanding than those of the current standard ECE R129 (i-Size). DualFix i-Size is an i-Size Car Seat that has been equipped with a large number of innovative safety features: for example the optimised side impact protection system (SICT) which features a special steel element inside the seat. Also the patented Pivot Link ISOFIX System which ensures that your child is well protected in the unlikely event of an accident, whether the impact comes from the front, from the side or from the back. It works by directing the force of the impact downward into the car seat and forward afterwards, so that the risk of suffering a head or neck injury are hugely reduced. The side wings of the Britax DualFix i-Size Car Seat are wider and cushioned which helps to absorb any side impact and the V-shaped headrest has been carefully created so that the movement of your child’s head during a collision is controlled in a way that protects and reduces injuries. The 5-point harness with soft neoprene chest pads keeps your monkey snug in their protective shell whilst preventing annoying and uncomfortable straps from digging into their delicate skin. The height adjustable support leg provides extra stability for the car seat via the vehicle floor. It minimises the tilting and reduces the forward movement during a collision, helping to protect your little soldier from getting hurt.

Britax believe that product development and production should be a process that is as closely linked as possible. That's why the DualFix i-Size Child’s Car Seat has been completely developed, designed and manufactured in Germany. And it has only been approved after numerous tests in Britax’s modern in-house crash test facility. That's how they can guarantee the best possible quality for consumers. And this applies not only to the seat components but also to the covers and fabrics, all of which are manufactured in Europe. The Britax DualFix i-Size Car Seat’s cover is machine washable and is easy to remove quickly without having to remove the harness first. All this to ensure that your little nippers are always safe on the road whilst looking awesome too!

The Britax DualFix i-Size Car Seat measures (H) 48 x (W) 44 x (D) 74 cm and weighs 15kg.
