Britax Advansafix IV M Car Seat - Blue Marble

Britax Advansafix IV M Car Seat - Blue Marble is a Group 1 2 3 Car Seat suitable for children weighing 9-36kg. It starts life as an ISOfix Car Seat, then changes to a Group 2-3 Car Seat which makes use of your vehicle's regular seat belt. If you're looking for exceptional safety features, premium comfort and longevity, then the Advansafix IV M is for you. Plus, in premium denim-style fabrics, it looks great too.

Why Should I Choose Britax Advansafix IV M Car Seat - Blue Marble?

Grows With Your Child

Britax Advansafix IV M works as a baby seat, a toddler seat, and a highback booster for your growing baby. For premium safety, you should use the integrated 5-point safety harness to keep your baby safely strapped in, and then swap it for a 3-point seat belt once your child reaches 15kg. The second key feature is the adjustable headrest, which can be fixed into many positions to suit your child. The third is the reclining seat, which can be set into three comfortable modes.

Pressure Distributing Harness

A 5-point harness keeps your baby tightly secured within the protective cocoon of the IV M car seat. Should you crash, the harness distributes the impact in five different places, reducing the force of the impact. The harness is made from soft neoprene chest pads, which are super comfy on your child as you buckle them up.

Reduces Risk of Abdominal Injury

Most car seats have 3 contact points. Britax Advansafix IV M Car Seat - Blue Marble has four. Positioned between your child's legs, this extra contact point reduces pressure on your child's delicate tummy area and holds the lap belt in the best position over your child's pelvic bones. As a result, it's safer in a crash.

Highback Booster Protection

The shell of this car seat provides protection from head to hip - particularly in a side impact. Upper and lower belt guides ensure that the seat belt is always in the right position, while the padded headrest is safe and comfortable, providing extra support for the head and neck.

Practical & Long Lasting

The Advansafix IV M is designed to last your child from 9 months to 12 years. With a quick remove, machine washable seat, it's easy to keep this Group 1 2 3 Car Seat looking great for years to come.
