The new generation KIDFIX M i-SIZE has been developed in partnership with leading car manufacturers, to protect children from around 4 years, right up to the age of 12 years. Approved to the latest i-Size regulation, it offers safety you can trust, and maximum comfort. Its slim frame will fit a wide range of cars, making it the ideal choice for your growing family’s needs.

The new KIDFIX M i-SIZE has been designed and approved to the new i-Size standard, passing stricter test criteria, in order to give greater protection to your child. The seat is developed in partnership with leading car manufacturers for optimum crash performance. Generously padded side wings and headrest help protect your child in the event of an accident.

Comfort and practicality at its core

Comfort and practicality come as standard with the KIDFIX M 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 M 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.

Sustainable Quality – caring for the world our children grow up in

The cleverly engineered KIDFIX M i-SIZE weighs around 1.3 kg lighter than its predecessor, and is designed and made in our factory in Germany – helping with shorter transport routes and minimising the impact on the environment. The packaging was also replaced with sustainable options: you’ll find the KIDFIX M i-SIZE packed in plant-based bags and recycled cartons from responsible sources. Even the mighty swift tags we use to attach product information are biodegradable on soil, resulting in no microplastics entering the ecosystem.

Redesigned seating area for optimum crash performance

Working in close partnership with leading car manufacturers, the seating area has been redesigned to help reduce the neck loads by up to 10%. *

Easy adjustable, ergonomic headrest

Kidfix M iSize headrest is designed specifically for the comfort of older children and can easily be adjusted to the correct position. Helpful markings at the back of the headrest guide parents to find the right headrest height every single time when they change the seat between cars or transport multiple children in the same seat.

Highback booster protection

Britax 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.
