This car seat gives you flexibility of use which is so important in the ever-changing daily lives of a growing family.

It can be easily adapted to fit children of different ages and sizes without the need to invest in an additional car seat - how well thought through is that?

Why should I choose the Britax Advansafix IV R Car Seat?


You will be impressed with how simple it is to manoeuvre the Britax Advansafix IV R car seat into what you need it to be, to fit your children and your car. Plus, you can rest assured that your child is benefiting from the latest, advanced safety features too. Using a specifically designed ISOFIX fitting, Britax have ensured that through the car seat's installation, it absorbs most of the force from any impact downward into the car's seat. The result of this is a reduced risk of head and neck injury.

Why choose the Britax Advansafix IV R from birth?

From 9kg, using the car seat's 5 point harness ensures your little'un is kept safely held but comfortably in place and all forces of impact are lessened. Installed using your car's ISOFIX ancorage points and the car seat's 'Top Tether'. With generous chest panels (which can be taken out and washed) and v-shaped head rest too, every journey will be a pleasurable experience especially with the choice of three recline positions to suit your child's needs.

Why choose the Britax Advansafix IV R for pre-school to junior school children?

If your child is approximately 15kg - or at junior or high school age then its easy to adapt the seat as a high back booster seat. This transition is easily done by changing the position of the headrest and storing the harness in the backrest. Britax have also incorporated their lap guard which ensures the straps are positioned not across your child's tummy but at their hips. This cuts the impact of a collision from the front by up to 35%. The result of this is to avoid injury to the abdomen should you be involved in an accident. 

All round protection and practicality

Covering all angles, the Britax Advansafix IV R includes protection from the side which is adjustable to suit the position of the seat on the left or right of the car. The 'side impact protection' device works by reducing the gap between the car and the side of the car seat. It absorbs the force of any impact from the side of the car so that your child remains safe.

Firm stability is a key benefit of the Britax Advansafix IV R car seat and is provided by 2 anchor points and the pivot link system. Both systems help reduce the risk of a head or neck injury for your child. 

Practically speaking, the Britax Advansafix IV R has a removable, machine washable cover which comes off leaving the 5 point safety harness untouched.
