ISOFIX AND TOP TETHER

Packed with more safety

Energi i-Size R129 comes with one-click, colour-coded ISOFIX connectors and top tether installation. In harness booster mode, use both to ensure the car seat stays in place. In highback booster mode, your vehicle’s seat belt is the main installation method, but you may still use the ISOFIX connectors and top tether for additional peace of mind.

Is Energi i-Size R129 Right for Me?

 

This 2-in-1 harness booster is packed with more safety features than ever before. Thanks to the top tether and automatic release ISOFIX connectors, Energi i-Size R129 will stay securely in place – even when your little one isn’t riding along. The integrated colour-coded indicators let you know when you’ve correctly installed the car seat, making it easier than ever to get on your way.

 

For even more peace of mind, Energi i-Size R129 meets i-Size and R129 standards in both modes and comes with Graco®’s Safety Surround™ Side Impact Protection.

 

This forward-facing car seat will provide security and comfort as your child grows from toddler to pre-teen. From 76 to 105cm (15 months to approx. 4 years), use the harness booster mode. The ISOFIX connectors and top tether keep the car seat in place, eliminating the need to use your vehicle’s seat belt. Energi i-Size R129’s 5-point harness will make sure your little one is positioned properly in the seat. 

 

When your child reaches 100cm (approx. 3.5 years), it’s time to switch to highback booster mode and store the harness away into the car seat’s integrated harness storage. Your vehicle’s seat belt will be the main installation method and the open-loop belt guides ensure that it’s positioned properly. You can keep the ISOFIX connectors and top tether installed for additional security.

 

Energi i-Size R129 adapts so your child will be comfortable at any stage. The no-rethread harness means you can easily adjust the harness and 15-position headrest together in one smooth motion. This 2-in-1 harness booster comes with built-in ventilation that works to keep your little one cool and comfy no matter the season. And the plush memory foam seat and padded armrests make sure every journey is cosy and comfy. Messes are inevitable so Energi i-Size R129 comes with covers that can be removed easily and tossed in your washing machine.

FAQs

What EU safety standards does Energi i-Size R129 meet?
There are currently 2 different car seat standards in the EU: R44 and R129. 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. 

 

Energi i-Size R129 meets the new R129 (legally known as ECE R129) 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

 

How do I know if I have correctly installed the top tether and ISOFIX connectors on Energi i-Size R129? 
Energi i-Size R129 comes with handy colour-coded indicators that confirm when the top tether and ISOFIX connector are correctly installed. Once you see green, you are good to go. 

 

What are the differences between harness booster mode and highback booster mode? 
Energi i-Size R129 is a 2-in-1 harness booster, which means you will get several years of usage in one car seat. In harness booster mode (76 to 105cm), the top tether and ISOFIX connectors ensure the car seat stays in place while the integrated 5-point harness keeps your growing rider properly positioned. You don’t need to use your vehicle’s seat belt. In highback booster mode (100 to 150cm), the integrated 5-point harness is removed and the vehicle’s seat belt keeps the child safely in place. For additional peace of mind, you may continue to use the top tether and ISOFIX connectors in highback booster mode. 

 

How do I switch Energi i-Size R129 from harness booster mode to highback booster mode?
When your child reaches 100cm (approx. 3.5 years), you may transition from harness booster mode to highback booster mode. Your child can stay in harness booster mode as long as their shoulders comfortably fit when the harness is at its highest setting. For a step-by-step guide on how to store the harness to switch to highback booster mode, we recommend you watch this video.

 

What is the maximum height and age for a child to ride in Energi i-Size R129?
This car seat can be used until your little one is your big one, up to 150cm or approximately 12 years of age.

 

How much does Energi i-Size R129 weigh?
Weighing only 7.2kg, Energi i-Size R129 is easy to move between various vehicles. 

 

Does Energi i-Size R129 need to be installed with a base? 
No, Energi i-Size R129 is not compatible with any base.

 

Can I machine wash Energi i-Size 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.
