Guardianfix 3 car seat

9-36 kg


Guardianfix 3 with torso protection is a car seat in the 9-36 kg group (ECE group: I/II/III), and it can be used in airplanes (TÜV certificate). It's been designed to best fit little travellers while providing the highest degree of safety.

That's why Guardianfix 3 can be tailored to your child in three ways, which means that the car seat:

  • grows – it has a head restraint that can be adjusted to 13 different levels,
  • extends – thanks to the option of adjusting the width of the backrest,
  • lengthens – it has a footrest that can be adjusted to five different levels.

Guardianfix 3 comes with an insert for young children, which ensures both safety and comfort even on long trips. This car seat features the latest technology and systems developed by German engineers, such as: Kiddy Shock Absorber, which minimises the force of impact during an accident, the HONEY COMB 2 technology, which improves shoulder protection for the child, as well as specialised torso protection. Guardianfix 3 is easy to install: this is possible thanks to the ISOFIX system and dedicated K-Fix+ system, which absorbs energy in the event of a collision, protecting the child.

Guardianfix 3 – tailored to your child

Certified for airplanes

Guardianfix 3 holds a special TÜV certificate, which confirms that the car seat can be tethered on airplanes.

Insert for young children

The car seat has a special insert for young children. It increases the safety of your youngster during travel, and is comfortable even on long trips. It makes the car seat even better tailored to your child's height.

Comfortable extendable footrest

Children don't like travelling with their legs hanging. That's why Guardianfix 3 has an extendable footrest that adjusts to five positions. Your child can freely rest their legs, and the car seat can be adjusted even to taller children.

Protection during sudden braking

The patented Kiddy Shock Absorber system significantly absorbs energy during sudden braking or a collision. Thanks to its properties, it absorbs the energy of the tightening waist belt, thus protecting your little one's developing, delicate pelvis until they're four years old.

Highest-class materials

The upholstery is made of the highest class of materials. It features a modern ventilation system, which helps control sweating even on hot days. The Guardianfix 3 car seat stands out thanks to its modern design. The upholstery is easy to remove and can be machine washed.
