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.

Sizing is way wayyy off.
Size: 5T, Color: Beige
I ordered three of these in different sizes for my 5yro&7yro -They’re average to their age sized kids. So ordered size 5 for my 7 yro (I read other reviews on it being big). Everything fit except the pants we’re closer to a size 8 (I ordered a size 5 remember) so disappointed. And a size 4 for my 5yro. The size 4 pants fit my 7yro! But not my 5yro at all. The rest of size 4 outfit was only a little big but not big enough to trade up to the other child. Unfortunately the gigantic pants are beyond the problem. They are definitely running 3 sizes too big. They’re not even something I could fix with my sewing machine. Company says they’ll work with you & send one item “free”but then say their shipping & handling fees are more expensive than the suit. Feels like it’s a ploy. update, the third suit arrived after a month of waiting and its a size 3-well its supposed to be a size 3. The pants are the size of an 8 year old. Im pissed. it's now past the return date, I have 3 suits for $45 each, and I had to rig the pants to fit my 4yro for my wedding. looked like crap obviously bc an 8yro's pants don't fit a 4 yro.. Don't bother buying from this company unless you're buying for an absurdly proportioned person.
