Based on over 50 years of experience and research, the KIDFIX III S from trusted name Britax Rӧmer offers the latest safety features so your child is always protected. Its ergonomic shape with a larger-than-standard seating area and V-shaped backrest supports your child in comfort as they grow, right up to around 12 years old, or until they no longer need a car seat.

Designed, developed and manufactured in Germany, the KIDFIX IIII S not only fits perfectly into most cars, but also meets the highest quality standards.

Protection

Britax Rӧmer’s highback boosters protect your child in three 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.

To further protect your child’s sensitive neck area in case of a frontal impact, Britax Römer has developed a shock-absorbing foam pad. This lessens the impact of your child’s chin on their chest, absorbing up to 30% of the energy in the brand’s internal testing. 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.

The SecureGuard helps to protect your child’s delicate abdominal area by adding an extra – fourth – 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 and at the same time allows your child freedom of movement during the journey.

The SICT reduces side 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.

Support and comfort

To provide maximum comfort, even for taller or bigger 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 KIDFIX III S 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.

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.
