What is the difference between Junior Maxi R44 and Junior Maxi i-Size R129?
There are currently 2 different car seat standards in the EU. R44 (legally known as ECE R44/04) car seats are divided into groups based on weight, with some covering multiple groups. Eventually, R44 car seats will no longer be available for purchase, but these seats are still safe to use. Junior Maxi R44 is based on these standards.
Junior Maxi i-Size R129 meets the new R129 (legally known as ECE R129) standards. The main differences in these standards are that car seats are based on your child’s height and undergo more side impact testing. Junior Maxi i-Size R129 is based on these standards. You can learn more about car seat standards and help figure out which car seat is right for you in our car seat buying guide.
Does the back of Junior Maxi i-Size R129 detach to use as a backless booster?

How do you safely keep Junior Maxi i-Size R129 in your vehicle when not being used?
To ensure the safety of you and anyone else in the vehicle, we recommend buckling in the highback booster even when there is no kid in it. This will keep it from being thrown from the seat in the event of a collision.
