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.

Softer than expected

Not as firm as I would like. Make sure you want a soft pillow if you choose this one. Seems high quality otherwise

Super comfortable and great neck support
Size: Queen (Mid Loft), Number of Items: 1
This pillow is super comfortable! It has support for the neck, which is so important so that my neck doesn’t end up creasing and cutting off your air. Great for side, sleepers or people that need a little bit more support. The height is about 5 inches- it appears firm, but it conforms to your neck shape and supports it. Great value for the money! I own four of them and guests finds them comfortable also

Perfect Pillow
Size: Queen (Mid Loft), Number of Items: 1
This is the best pillow I’ve ever had! Supportive yet soft. Never goes flat. I’m a side sleeper and I have neck and shoulder pain and this pillow keeps my head and neck in alignment. I’m buying a set for our camper and our 2nd home so I can sleep comfortably wherever I go. Price point is spot on for the quality of pillow.
