Is Extend LX R129 Right for Me?


Extend LX R129 is designed to keep your little one rearward facing longer since that’s the safest way for them to travel. This upgraded version of our original Extend R44 convertible car seat meets the EU’s R129 standards which means it has undergone more side impact testing, is categorised by height instead of weight, and keeps your child rearward facing for more time.


In true convertible car seat form, Extend LX R129 can go forward facing once your little one reaches a minimum of 75cm and 15 months of age, giving your family more versatility and value over time. As your baby becomes a toddler, you’ll be able to easily adjust the no-rethread harness with just one hand. And the 6-position headrest ensures they always have proper head and neck support. Make sure your little rider is always comfortable by taking advantage of the 4-position recline.


All the safety features will give you additional peace of mind. Extend LX R129 comes with Safety Surround™ Side Impact Protection, which provides superior side impact protection and powerfully protects your little one’s head from that first trip home from the hospital until they reach approx. 4 years. Vehicle seat belt installation is more intuitive thanks to the dual lock-offs and clear, colour-coded installation paths that guide you in connecting the car seat securely to your vehicle. The 5-point harness is adjustable with only one hand and makes sure that your little one is nice and snug.


Plush fabrics and padded harness pads create comfort on each and every ride. The convertible car seat’s machine-washable covers are easy to clean in case there are any spills while you’re on the road together. For the littlest riders, a comfy padded newborn insert is included and is also machine washable.

What is the difference between Extend R44 and Extend LX 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. Extend R44 is based on these standards.


Extend LX 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, undergo more side impact testing, and ensure children sit rearward facing until they reach 15 months and 75cm. Extend LX R129 is based on these standards. In our car seat buying guide, you can learn more about car seat standards and help figure out which car seat is right for you.


How long should I keep my child rearward facing in the Extend LX R129 car seat?
Under R129 standards, it is required to keep your little one rear-facing until 15 months and 75cm. We recommend keeping your child rearward facing as long as possible because this seat position will better protect your child's head, neck and spine in case of impact. For this reason, we advise rearward facing up to 105cm or approximately 4 years of age.


How many recline positions does the Extend LX R129 car seat have?
The Extend LX R129 convertible car seat has 4 total recline positions — 1 in rearward facing and 3 in forward facing. This means your child's head and neck will always be properly supported.


Can I machine wash Extend LX R129’s seat covers?
Yes, you can wash the covers in your washing machine with cold water only on the delicate cycle. Drip dry and do not use bleach.


What is the maximum height and age for Extend LX R129?
This incredible 2-in-1 convertible car seat can be used until your little one reaches 105cm, which is approx. 4 years of age.

Recommended Use

This car seat is suitable from 40-105cm (birth to approx. 4 years)


Rearward-facing harnessed seat suitable from 40cm to 105cm (birth to approx. 4 years). Keep your child rearward facing as long as possible because it is the safest position.

Care & Maintenance
