Always perfectly protected
Based on over 50 years of experience and research, the KIDFIX III S offers the highest level of safety. Thanks to the latest safety features, your child is always perfectly protected – from head to hip. So you can be reassured that your little one is safe and sound.
Designed to the highest standards
Designed, developed and manufactured in Germany, the KIDFIX IIII S not only fits perfectly into most cars, but also meets the highest quality standards. And this also applies to our covers which are made of durable and easy-care materials – so any mishap can easily be taken care of.
Ultimate comfort for all passengers
The KIDFIX III S is one of the most comfortable child seats on the market thanks to its ergonomic shape. Due to the larger seating area and v-shaped backrest the seat grows perfectly with your child – always offering the best possible support whatever their size.
Unique protection for the neck and chest
Despite good planning and careful driving, you can never prepare for a collision. To protect your child’s sensitive neck area in case of a frontal impact, Britax Römer has developed a shock-absorbing foam pad. It prevents the impact of your child’s chin on their chest, absorbing up to 30% * of the energy. A jerky forward head movement is reduced and the neck is protected. At the same time it provides additional padding around the edges of the seat belt.

Ergonomically optimised seating area
To provide maximum comfort, even for taller children, the seating area is approximately 20% larger than similar models. The improved shape and extra-soft padding make for a comfortable and ergonomic seating position on longer journeys.
The SecureGuard helps to protect your child’s delicate abdominal area by adding an extra – a 4th – contact point to the 3-point seat belt. By keeping the lap belt in an optimal position over your child’s pelvic bones SecureGuard helps reduce abdominal forces in the event of a frontal collision by up to 35 %*, and at the same time allows your child freedom of movement during the journey.

Advanced Side Impact Protection – SICT
Our SICT offers superior protection to your child in the event of a side collision. It reduces impact forces by minimising the distance between the car and the car seat and deforms to absorb the energy before it reaches your little one. To benefit from the protection, simply adjust the SICT on the side of the car seat closest to the door.
Easy adjustable, ergonomic headrest
Our headrest is designed especially for older children, when using the 3-point seat belt to secure them in the car seat. It can easily be adjusted to the correct position, just above your child’s shoulders, with one hand – even while they are sitting in the seat. Plus the headrest is ergonomically designed to support your child’s head when they fall asleep.
Easy adjustable V-shaped backrest
Designed to give optimum support to your growing child, the V-shaped backrest provides more space for their back and shoulders. Plus, the backrest automatically adjusts to match the angle of the vehicle seat, providing a better fit and a comfortable position for your child.
Highback booster protection
Our 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; and the padded headrest provides safety and comfort for your child’s head and neck.
Things can get messy in the car – drinks can spill and children can get car sick. That’s why we’ve designed a machine washable seat cover that can easily be removed, so you can clean up quick and get on your way.
Belted with ISOFIX attachment
This child car seat has to be installed using the vehicle’s 3-point seat belt as well as the ISOFIX anchorage points in your car. This ensures a firm and secure connection between the child car seat and car, even when your child is not sitting in it.
KIDFIX III S features integrated ISOFIX connectors that enable you to attach the car seat to the ISOFIX anchorage points in your car. The ISOFIX installation system offers superior performance in the event of an accident when your child is secured with the car’s 3-point seat belt and ensures that the car seat is always firmly attached to the car, even when it is not being used by your child.
Check the vehicle list or BRITAX FIT FINDER® to see if the car seat is compatible with your car.
This child car seat can be installed with the car’s 3-point seat belt. This option is handy if you will be transferring the car seat to different cars which may not all have ISOFIX anchorage points. Seat belt guides on the car seat will help you install the seat correctly.
Check the vehicle owner’s manual for suitable seating positions.
