Child car seat GRACO Booster Max R129 for 135–150 cm children, Iron

GRACO Booster Max R129 for 135–150 cm children in Iron is a booster seat intended for older children who have outgrown harnessed car seats but still require proper belt positioning. Compliant with the R129 regulation, the Booster Max R129 lifts the child to the correct seating height and offers side impact protection to help align the vehicle's three-point seat belt across the shoulder and pelvis. The design focuses on stable placement in the vehicle and straightforward integration with standard car seats.

Advantages

The GRACO Booster Max R129 provides improved belt fit through a raised seating position and clearly defined belt guides. Side protection elements reduce lateral movement and contribute to passive safety during travel. The seat is lightweight enough for easy installation and transfer between vehicles, while its durable cover materials simplify cleaning and maintain appearance over time.

• Children with height from 135 cm up to 150 cm

• Transition from harnessed child seats to vehicle belt use
• Vehicles with standard three-point seat belts

How to use

Place the booster on the vehicle seat and ensure it sits flat and stable against the seat cushion. Position the child so their back is aligned with the vehicle seat and use the integrated belt guides to route the vehicle's three-point seat belt: the lap belt should rest low across the pelvis and the shoulder belt should pass over the shoulder and collarbone without crossing the neck. Confirm the belt is snug and not twisted. Adjust the child's seating position as needed to maintain correct belt alignment during travel.

Usage recommendations

Use the GRACO Booster Max R129 only for children within the specified height range. Regularly inspect the seat and cover for wear and wash the removable cover according to manufacturer instructions. Do not use the booster on seats with incompatible belt systems and avoid placing the child in the booster without the vehicle's three-point belt properly fastened.
