Carbon Neutral, GREEN SENSE + Made in Germany

Britax continuously works to further reduce it keeping in mind that certain materials are needed to focus on the main purpose: transporting little one safely. Besides being carbon neutral, the Kidfix i-size is also made in Germany and is packed in plant-based bags as well as recycled cartons from responsible sources. It is a GREEN SENSE fashion, and the fabric covers of this collection are made from 100% recycled PET plastic bottles.

Comfort + practicality at its core

Comfort and practicality come as standard with the Kidfix i-size. The generously padded soft fabric covers and carefully placed air ventilation holes on the shell ensure your child travels in comfort for longer. The slim design of the seat allows for three Kidfix i-size seats to be installed in the back row of a wide range of cars, whilst the headrest markings help the parents find the right headrest height every single time.

Expert protection

The Kidfix i-size has been designed and approved to the new i-Size standard, making it the safest Kidfix i-size to date. Every feature on the seat has been developed with one thing in mind - maximum protection. The proven technologies of XP-PAD, SICT and SecureGuard, now combined with the redesigned seating area for optimum crash performance, offer all-around protection.

Fab seat

"We bought this for our older child about 3 years ago and now buying it for number two. Super easy to install and suitable as a first booster all the way up to when they don’t need a seat (daughter is a tall 7. 5yo and there’s still lots of growing room). Like the additional safety features. Perfect in every way!"

— Emily B. (5/5)

Great Product,

"I recently purchased the Britax Romer KIDFIX i-Size High Back Booster Car Seat - Cosmos Black and I am beyond impressed with its quality and features! It ticks all the boxes for what I was looking for in a car seat. The level of comfort this car seat provides is exceptional! The padding is soft yet supportive, and my child seems to love it, even on longer car rides. I was initially concerned about installation, but the process was surprisingly easy with the clear instructions and helpful system. This is hands down the best car seat I’ve owned. It’s a bit of an investment, but the safety, comfort, and ease of use make it 100% worth it. If you’re looking for a reliable car seat that will last you for years, I highly recommend this one!"
