R129-compliant (i-Size ready) Suitable for children 100-150cm in height.

The new HI-LINER from Britax Römer 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 was developed according to the new i-Size standard and is approved according to the latest R129 regulations. Thus, the seat provides reliable, and future-required i-Size safety for your child.

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.

The Britax Römer 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; the padded headrest provides safety and comfort for your child's head and neck.
