Why you should buy the Britax Romer Kidfix i-Size Car Seat

Britax Romer developed the Kidfix i-Size car seat, approved under the R129 standard, also known as i-Size. Suitable for heights from 100cm to 150cm, it is equipped with the SecureGuard fourth anchorage/contact point and the XP-PAD cushion, to protect the child from a frontal impact, while the redesigned SICT system offers greater protection in the event of a side collision. All of this combined with a redesigned seat area to offer an optimal response in case of impact and ventilation holes in the structure for greater comfort during the journey.

Optimized seating area
The seat area has been redesigned to help reduce neck loads by up to 10%, according to internal tests carried out by Britax Römer with a Q10 dummy, representing a 10-year-old child.



Redesigned SICT
The new SICT system offers improved protection in the event of a side collision. The KIDFIX i-SIZE features a removable element, adjustable in two positions, which is placed on the side of the backrest closest to the door to minimize the distance between the vehicle and the car seat. According to Britax Römer's internal tests, SICT technology reduces the forces of a side impact by up to 40%, deforming to absorb energy before it reaches the child.

XP-PAD
The KIDFIX i-SIZE features the XP-PAD, a cushion that covers the diagonal seat belt and protects the child's neck and chest in the event of a collision or sudden braking.According to tests carried out by the manufacturer in 2019, this impact-absorbing cushion patented by Britax Römer diverts up to 30% of the energy from the child's neck and prevents cervical hyperflexion by reducing head movement. In addition, it provides comfortable padding around the seat belt.



SecureGuard
The proven SecureGuard helps protect your child's delicate abdominal area by including an extra fourth attachment point to the 3-point seat belt. By keeping the lap belt in an optimal position over the child's pelvic bones, SecureGuard helps reduce forces on the abdomen 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.



Easy-to-adjust ergonomic headrest
The headrest has been specifically designed to offer maximum comfort to children and can be easily adjusted to the correct position (there should be a two-finger distance between the shoulders and the headrest).

The useful marks on the back of the headrest guide parents to find the correct height every time they change the car seat or transport different children in the same car seat.


Ventilation holes
To ensure the child's comfort even on the longest journeys, the structure has carefully placed ventilation holes to provide greater air circulation.

Installation with Isofix or belt
The KIDFIX i-SIZE offers two installation options:
- Isofix and three-point belt
- Vehicle's three-point belt

Product specifications
With a width of 44 cm (without SICT), it is possible to place three car seats in the rear seats of many cars, especially those with i-Size seats or with ISOFIX in all three seats.
