Britax Romer Advansafix i-Size Car Seat - Fossil Grey

Part of the new innovative Green Sense range, the Britax Romer Advansafix i-Size Car Seat in Fossil Grey's fabric is made with 100% recycled polyester and is suitable from 15 months to 12 years. This seat offers extended harnessing and a whole host of safety and comfort features.

Why should I choose Britax Romer Advansafix i-Size Car Seat - Fossil Grey?

Extended 5-point Harness Wearing

Your child can benefit from the safety of extended harness wearing up until they reach 21kg. When it is time to switch to the vehicles 3-point seat belt, the Flip&Grow feature makes it possible in just a few simple steps. Simply adjust the headrest and you can stow away the harness in the backrest. Next, switch the Flip&Grow adjustment plate so that the SecureGuard is above the seat and you are good to go.

Maximum Protection with SecureGuard

SecureGuard helps to protect your child's delicate abdominal area as it adds a 4th- contact point when you use the 3-point seat belt. This keeps the lap belt in an optimal position over your child's pelvic bones helping to reduce abdominal forces by up to 35% in event of a frontal collision, whilst still giving freedom of movement.

Advanced Side Impact Protection

In event of an unexpected side collision, the Advanced Side Impact Protection reduces the force of the impact by minimising the distance between the car and the car seat, absorbing energy before it reaches your child. All that needs to be done to benefit from this safety feature is to simply adjust the Advanced Side Impact Protection on the side of the seat closest to the door.

Extra Safety

As well as SecureGuard and the Advanced Side Impact Protection, the car seat also has a shock absorbing foam pad to protect your child's sensitive neck area in the event of a frontal impact. Up to 30% of the energy of such an impact is absorbed and your child's head movement is reduced. The specially designed V-shaped headrest ensures optimal protection in the event of a side impact, by controlling the movement of your child's head, as well as providing ultimate comfort. The top tether minimises the rotation of the car seat, therefore reducing possible injuries to the head and neck area offering even greater stability and security than a seat with conventional tethers.

Ultimate Comfort

The EasyRecline system on this seat can be used for all ages and allows you to adjust the recline of the seat, even when your child is in it. You can also easily adjust the headrest and harness so that no matter the size of your child, there is a comfortable position to suit them.

Recycled Materials

This car seat is part of Britax Romer new innovative Green Sense Range. 100% recycled polyester is used in the making of the fabrics; up to 29 plastic PET bottles per product are turned into soft yarn and then spun to make premium fabric covers. The diamond-patterned mesh fabric, which is also made from 100% recycled materials, has been integrated into the design to aid air circulation which will keep your child cool and extra comfortable on long journeys or hot days.
