Britax DualFix i-Size Car Seat

Britax DualFix i-Size Car Seat is a highly adaptable option for both you and your baby. A 360 degree rotating seat makes it practical as well as safe. Your baby will love travelling in the Britax Dualfix i-Size Car Seat from birth all the way up to 4 years.  

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

The Britax Dualfix i-Size Car Seat is a 360 degree rotating car seat. It is a group 0+/1 seat which can be easily installed thanks to the new ISOFIX connectors.  It allows your baby to sit rearward facing or forward facing. One of the most practical features of the Britax Dualfix i-Size Car Seat is the ability to rotate the seat round so it faces your car door. This makes harnessing your child in and out of the seat so much easier. 

12 recline positions, one of which is an ergonomic lie flat position, mean the Britax Dualfix i-Size Car Seat grows with your baby and allows you to find the most comfortable position. 

Safety has been a key consideration in the design and construction of the Britax Dualfix i-Size Car Seat. Safety features aim to keep your baby safe whatever happens on your travels. An adjustable rebound bar helps in to prevent the seat from tipping during an impact. Side Impact Protection keeps your baby protected on either side of the seat. The V shaped headrest is designed to control the movement of your baby's head and to be extremely comfortable as well as safe. There is also a height adjustable support leg to further minimise any risk of the seat tilting.

The cover of the Britax Dualfix i-Size Car Seat is quick and easy to remove and can be machine washed. Removing the cover does not require the harness to be removed which is another added bonus!
