The new HI-LINER is the go-to car seat for anyone looking for a reliable and easy to use highback booster seat.
Designed and manufactured in Germany, the HI-LINER meets our highest standards in comfort and safety on the road.
HIGHLIGHTS
I-SIZE SAFETY
The HI-LINER was developed according to the new i-Size standard and is approved according to the latest R129 regulations, which are mandatory from September 2023. Thus, the seat provides reliable, and future required i-Size safety for your child.
COMFORT MEETS PRACTICALITY
The optimised seating area and the generously padded soft fabric covers offer additional comfort, especially on long journeys.
Thanks to the slim design, up to three HI-LINER seats can be installed in the back seating area of a wide range of cars.
When switching the seat between vehicles, helpful headrest markings make it easy to get the right setting every time. The ISOFIX system makes the installation of the seat simple and safe.
SUSTAINABILITY MADE IN GERMANY
Unlike competition, BRITAX RÖMER manufactures the vast majority of car seats in Germany.
Not only does this ensure the highest production quality – it also shortens transport distances and therefore significantly lowers the impact on the environment.
To make the HI-LINER even more sustainable, it comes in compact recycled carton packaging which is efficient in transport.
FEATURES
EASY ADJUSTABLE, ERGONOMIC HEADREST
Our headrest is designed specifically for the comfort of older children and can easily be adjusted to the correct position.
Helpful markings at the back of the headrest guide parents to find the right headrest height every single time when they change the seat between cars or transport multiple children in the same seat.
THREE SEATS IN A ROW
The seat's slim and compact design allows for three seats to be installed in the back row of a wide range of cars.
NEW ISOFIX CONNECTORS
The HI-LINER features our new ISOFIX connectors. The connectors can be operated independently of one another and therefore make the installation of the seat even easier.
HIGHBACK BOOSTER PROTECTION
Our highback boosters protect your child in 3 ways: the seat shell provides head to hip protection for your child, especially in the event of a side impact; the upper and lower belt guides provide correct positioning of the seat belt; and the padded headrest provides safety and comfort for your child’s head and neck.
ADJUSTABLE BACKREST
The child seat’s adjustable backrest allows you to match the angle of the vehicle seat, providing a better fit and a comfortable position for your child.
INSTALLATION
Belted with ISOFIX attachment
This child car seat has to be installed using the vehicle’s 3-point seat belt as well as the ISOFIX anchorage points in your car.
This ensures a firm and secure connection between the child car seat and car, even when your child is not sitting in it.
HI-LINER features integrated ISOFIX connectors that enable you to attach the car seat to the ISOFIX anchorage points in your car.
The ISOFIX installation system offers superior performance in the event of an accident when your child is secured with the car's 3-point seat belt and ensures that the car seat is always firmly attached to the car, even when it is not being used by your child.
Our i-Size car seats will fit all i-Size approved seating positions, so please check your vehicle owner's manual for i-Size approved seating positions.
