Get a major boost of convenience, confidence and comfort with Affix i-Size R129. This highback booster has it all including built-in ISOFIX connectors that keep the car seat safely fixed in place — even when your growing child isn’t along for the ride. Plush premium padding and breathable fabrics are the cherry on top of this highback booster that truly does it all.

Our original Affix R44 highback booster has been adapted to meet i-Size and R129 standards. This means Affix i-Size R129 has undergone more extensive side impact testing and is compatible with any i-Size approved vehicle, reducing the risk of incorrect installation.

Affix i-Size R129 comes with colour-coded ISOFIX connectors for additional peace of mind. Although your vehicle’s seat belt is the main installation method for this highback booster, the ISOFIX connectors provide additional security and ensure the car seat stays in place even when it is not being used.

This car seat is equipped with Safety Surround™ Side Impact Protection, which wraps around your child and provides enhanced head and body protection.

If you are looking for a highback booster with exceptional safety features, Affix i-Size R129 is here to help. This car seat comes with one-click ISOFIX connectors – a first for a Graco highback booster. While you still use the vehicle’s seat belt as the main installation method, the ISOFIX connectors provide extra protection to all other riders by ensuring the car seat stays in place and doesn’t become a projectile when not in use.

Affix i-Size R129 meets the EU’s latest R129 safety standards and is i-Size certified, which means that it will correctly fit into any i-Size approved vehicle. For even more peace of mind, Safety Surround™ Side Impact Protection wraps around your child, giving them enhanced head and body protection. To ensure proper head and neck support at any stage, adjust the 10-position headrest with just one hand.

Suitable for kids between 100 and 150cm (approx. 3.5 to 12 years), this highback booster is packed with features that are focused on their comfort. Your growing child will stay cool no matter the season thanks to the car seat’s side ventilation design that uses breathable fabrics to create a nice and steady airflow. The premium padded seat with padded armrest covers means they will stay comfy for all your journeys together, and the 2 retractable cupholders come in handy when you’re on the go.

Weighing only 4.2kg, you can easily move Affix i-Size R129 between vehicles. In case of any spills or messes, simply remove the fabric covers and throw them in your washing machine for a quick cleaning.
