The Britax Romer HI-LINER is an ideal car seat for anyone seeking a dependable and straightforward highback booster seat. Constructed and produced in Germany, the HI-LINER adheres to our highest standard in comfort and security when travelling.

The Britax Romer HI-LINER meets the stringent i-Size R129 standards and is compliant with the mandatory regulations beginning in 2023. It provides reliable safety functions and a comfortable seating area with a generously padded fabric cover. Its slim design allows up to three HI-LINER seats to fit in the back of various cars, which is facilitated by helpful headrest markings and an ISOFIX system for easy installation. Britax Romer 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.

Our headrest is tailored to the comfort of older children, and can be adjusted to the correct height with helpful markings on the back for simple reinstallation. The HI-LINER boasts our new ISOFIX connectors, which can be operated independently, simplifying the installation process. The slim, compact design fits in the back rows of a variety of vehicles, fitting up to three seats. In case of messes, the machine washable seat cover can be conveniently removed for quick cleaning.

The Britax Romer HI-LINER ensures optimal protection & comfort for your child. The shell provides head-to-hip protection, while the upper & lower belt guides ensure precise seat belt positioning. The padded headrest provides safety & comfort, and the adjustable backrest creates a comfortable fit for your child. This child seat requires installation with the vehicle's 3-point seat belt & ISOFIX attachment points.

HI-LINER features integrated ISOFIX connectors for a firm, secure connection to your car's ISOFIX anchorage points. This installation system offers superior performance in the event of a crash, along with the car's 3-point seat belt, and ensures a stable attachment when the car seat is not in use. This Britax car seat can be conveniently fitted with a standard 3-point seat belt. It is a helpful option if the seat needs to be moved between cars without ISOFIX connections. Clear seat belt guides ensure a precise installation.

Perfect Tesla Car Mount Charger!
This charger is amazing! Fits my Tesla screen perfectly, charges my phone fast, and the magnetic hold keeps it secure. Love the LED RGB lights and heat protection — looks great and works flawlessly. Highly recommend!

Would be better with longer cable and without the LED light.
I like that the install is very easy, non-permanent, and can be very quickly removed if needed. It fast charges and the magnets are strong (the reviews that say it doesn’t hold probably aren’t using a MagSafe case). That said I have two annoying issues: 1) There is a light that comes on when the car is turned on. If you don’t put your phone on the charger it will say on for a minute or two and then eventually turn off. 2) The included USB-C cable is too short. It only just barely reaches the outlet in the front bottom center console. It would be better if they had included a 6ft with a 90-deg connector to draw power from the back seat ports. 3) It doesn’t not include a charger. In all, the mount and charger are fine, but be prepared to spend an extra $20 on a longer cable and charger to make it all work.
