A 9-36 kg car seat with the Kiddy Shock Absorber system and special impact shield, which absorbs energy in a head-on collision

Kiddy Shock Absorber system

Protected by a patent, the innovative Kiddy Shock Absorber system absorbs energy when the waist safety harness tightens in a collision or during sudden braking. This solution guarantees protection not only for your child’s delicate pelvis, but also for their cervical spine and brain.

Honey Comb 2 technology

To ensure the utmost safety, the car seat has a shell, wide side walls and sides of the headrest made of elastic and durable materials, as well as the unique Honey Comb 2 system, which provides excellent shock and impact absorption during a collision.

K-Fix+ system

The ultra-modern K-FIX+ system means that the car seat can move from side to side, which in the event of a collision significantly decreases the force of a side impact, and also makes it easier to position against the car’s bench seat.

Practical and effective impact shield

Guardianfix 3 features an additional, durable impact shield, which is installed in the car seat to improve the safety of smaller children. In the event of a collision, this solution absorbs the force of a head-on collision and acts similarly to an airbag (at the moment of impact, the shield absorbs the energy generated).

Adjusts to your child’s height and age

The Kiddy Guardianfix 3 car seat can be adjusted in three directions – height, width and depth – to precisely tailor it to your growing youngster. Travel comfort is ensured thanks to the headrest, which can be adjusted to 13 different levels, and the deep seat with a slide-out leg support that can be adjusted to five positions.

The Kiddy Guardianfix 3 car seat is designed for children who are 1-12 years old or weighing 9-36 kg, and is installed in the forward facing position. The product has successfully passed rigorous safety tests, including ADAC (with a 1.9 rating), meets the highest standards, including standard ECE R44/04, and holds the TÜV certificate, which means it can be installed on a plane. Your child’s safety during travel is improved by the innovative Honey Comb 2 technology, which is a material that absorbs the force of impact in the event of a collision, as well as the Kiddy Shock Absorber system, which protects the little passenger in an accident or sudden braking by minimising the force acting on your youngster’s sensitive body parts, including their pelvis, cervical spine and head. The car seat’s technological advancement and functionality are further enhanced by the K-Fix+ connector system, three-point safety harness, insert for young children, and impact shield for smaller children, which acts as an airbag in the event of an accident.

However, Guardianfix 3 is more than just the highest level of safety. It’s also unprecedented travel comfort. The backrest reclines from 90° to 115° from the car’s bench seat, and the leg support, which slides out and can be adjusted to five positions, can be set to maximise your child’s comfort. In this regard, also important are the soft, pleasant-to-the-touch and easy-to-wash fabric, as well as extensive car seat adjustment options. This is because Kiddy Guardianfix 3 grows with your little one, adapting to their age and height in terms of height, width and depth.
