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.

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
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.
