Specially designed to control the movement of your child’s head, our V-shaped headrest ensures optimal protection in the event of a side collision while providing ultimate comfort at the same time. Plus, the headrest and harness can easily be adjusted from the front of the seat to suit your child’s height. Although we are happy that the newest version of ADVANSAFIX i-Size is tested to the i-Size R129 regulation and so can only be used forward facing from 15 months, we would also advise that it is safer for any child to be rear-facing for as long as possible. It lasts a great amount of time from 15 months up to when your child no longer needs a car seat, even surpassing the 135cm law, up to 150cm. It's a great price when you think how long it will actually last you, meaning you could only need two car seats during their childhood. The Britax Rӧmer ADVANSAFIX i-Size is based on the ADVANSAFIX IV R, but has been updated and approved to the new i-Size regulation. To do this, it has had to have more safety features to pass. It is suitable for use from 76 to 150cm, which is from approx. 15 months until 12 years old. We are pleased that the newest version of the ADVANSAFIX, as a forward facing only seat, is suitable from 15 months as a minimum, as rear facing is much safer for younger children. It's also important to remember to adjust the SICT (side impact cushion technology) after installing. Working in a screw action, you just unscrew the cap at the side closest to the door until it fills the gap between the door and the seat. This reduces the impact of a side collision and absorbs some of the energy that could otherwise be going into the side of the seat and your little one.

Innovative FLIP&GROW function allows you to make a an easy swap from 5 point harness to 3 point seat belt The ADVANSAFIX i-Size is suitable from 76cm, which is your average 15 month old. The i-Size regulation means that you can not forward face before 15 months old as a minimum, so this car seat cannot be used before that age. The harness is to be used up to 102cm, and has a higher weight limit of 21kg. This is brilliant for children that are higher weight centile, like our two year old tester at nearly 18kg! Our only issue is that the height of 102cm is not quite up to the height of other car seats that last to 105cm or around 4 years old and 18kg maximum weight. So it could be outgrown in height even if they have weight left. As a new seat, the ADVANSAFIX i-Size is yet to go through the ADAC testing, but we are keen to see how it does and if it beats the ADVANSAFIX IV R's score of 2.3! We will update our review accordingly once it has. Things to look out for…The Flip&Grow function allows you to easily change the integrated 5-point harness to the car’s 3-point seat belt making it simple to move your child to the next stage. The Easy Recline function also makes it easy to recline the seat without readjusting the installation, meaning your child is comfortable at all times.

The extra soft neoprene chest pads fit conveniently on your child’s chest, helps to reduce their movement in the event of an impact. In addition, you can easily remove these for washing without disturbing the harness. We are big fans of Britax Rӧmer and the great child car seats that they design and make, all in-house in Germany.

As with all Britax Rӧmer car seats, the ADVANSAFIX is designed with the safety of the child at the forefront, so includes lots of features to protect them.
