Britax Advansafix M i-Size Car Seat - Burgundy Red

Britax Advansafix M i-Size Car Seat - Burgundy Red is a must have i-Size car seat suitable from 15 months all the way to 12 years old. The Advansafix M is a forward facing car seat, and will last baby through years of travelling with ultimate safety and comfort from Britax.

Why Should I Choose Britax Advansafix M i-Size Car Seat - Burgundy Red?

Britax Advansafix M i-Size Car Seat - Burgundy Red is a must-have i-Size car seat for your little one. Protecting your little one from their toddler years all the way to when they no longer need a child car seat, it offers ultimate protection throughout every journey. What's more, it complies and exceeds European i-Size R129 regulations.

Britax Pivot Link ISOfix System

As well as this, the Advansafix M offers a patented Pivot Link ISOfix System. This system directs the force first downwards into the vehicle seat, then forwards - more gently. This reduces the risk of head and neck injury for your little one.

5-Point Harness Safety

What's more, Britax's 5-point harness system is the safest way to secure your child in a car seat. This is because it keeps baby safe and tight in the seats protective shell. In the unlikely event of a collision, the harness therefore distributes the forces of the impact across 5 different points - two at the shoulders, two at the hips and one between the legs. This helps to protect baby from all directions of impact.

You will love Britax's updated, soft neoprene performance chest pads. These fit comfortably on your child's chest. This helps to reduce your little one's movement in the seat, and adds even greater comfort to the 5-point harness. Plus, they can be easily removed for washing without disturbing the harness.

Highback Booster Protection

Additionally, the highback booster protection on the Britax Advansafix M i-Size Car Seat - Burgundy Red protects your child in three different ways. The seat shell provides head to hip protection, especially in the event of a side impact. Then, the upper and lower belt guides provide the correct positioning of the seat belt. Finally, the padded headrest provides safety and comfort for baby's head and neck.

The V-Shaped headrest is specially designed to control the movement of your child's head. This therefore provides optimal protection in the event of a side collision, all whilst providing ultimate comfort at the same time. Plus, you can adjust the headrest and harness from the front of the seat to suit your child's height.

SecureGuard With Flip&Grow

Britax's innovative Flip & Grow system is offered on this i-Size car seat. Firstly, the SecureGuard helps to protect your child's delicate abdominal area by adding an extra contact point to the 3-point seat belt. By keeping the lap belt in an optimal position over your little one's pelvic bones, the SecureGuard helps to reduce abdominal forces by up to 35%, and at the same time allows baby's freedom of movement.

Once your baby reaches 15 kg and up to a maximum of 21 kg, you must change from an integrated 5-point harness to the car's seat belt. Flip&Grow allows this in just a few simple steps.

Top Tether For Ultimate Protection

What's more, the V-shaped top tether minimises the rotation of the car seat and thus reduces possible injuries in the head and neck area in the event of a collision.

EasyRecline Seat

EasyRecline on the Britax Advansafix M i-Size Car Seat - Burgundy Red is suitable for all ages and allows you to adjust the seat into a comfy position for baby - even when they're in the seat.

Quick Remove Cover For Quick Cleanups

Last but not least, the cover of this seat can be quickly and easily removed for your convenience. So crumbs, smudges and shoe scuffs can be cleaned off in a quick wash!
