The Kiddy Smartfix is unique! Between the ages of 4 and 12, children will grow around 4 to 5 centimetres per year. This results in an average growth of almost half a metre during the life of a child car seat. Therefore the Smartfix is designed to easily adjust along three dimensions – height, width and depth - to perfectly fit a growing child, no matter what their age.

With its 14 unique height and width adjustments and three leg support settings, the Smartfix can expand to become 9 cm wider, 15 cm taller and 6 cm deeper to offer the perfect fit every time! So even larger children, up to 150 cm tall, should never feel uncomfortable especially on longer journeys. The child will always sit securely and comfortably in an ergonomically correct position.

The Smartfix uses ISOFIX connectors to provide a secure attachment to the car. High performance impact-absorbing materials are built into the head and shoulder areas to protect the child. The Kiddy Shock Absorber has new geometric design. The Shock Absorber, along with the diagonal belt guide, will reduce forces / load in the event of a frontal impact.

Stiftung Warentest, ADAC and ÖAMTC awarded the Smartfix a 'good' result in their stringent safety tests. The safety test experts highlighted in particular that the Smartfix had a “very low risk of injury” in a side impact. The experts noted the very low risk of incorrect operation; the simple installation of the seat in the car; the spacious seat for the child, and the good visibility out. The testers concluded that the Smartfix was a: “Good child seat for children from approximately 3 years onwards, with an additional ISOFIX fitting option (in cars fitted with this). This increases the lateral stability, and prevents the tilting of the seat during cornering.” With quality and workmanship has being rated as 'very good' and reference made to the comfortable seat and extending leg rest; the Smartfix really is the smart way to transport your child!

Safety features

New geometric Kiddy Shock Absorber

The patented Kiddy Shock Absorber (KSA) has a new  geometric design. The KSA reduces the force created upon impact in a head on collision. This allows the seatbelt to  pull taut; and the energy created is transferred and absorbed by the materials inside.

Optimized side impact protection

The side impact protection offered by our high-performace materials 'Honey Comb V2) has been optimised with new side geometry, making the head and shoulder protection for the child, even more effective without obscuring their view.

Perfect fit

The Smartfix has 14 adjustable head & shoulder position settings to ensure this seat perfectly fits your child's body dimensions in height & width. The tight-fitting side cushioning elements offer the best protection. Adjustment is quick & easy for each stage as your child grows.

High-tech material

Great side impact protection! The head and shoulder area in children is especially vulnerable, with the head being relatively heavy compared to the rest of the body. By using the high-performance material Honey Comb V2 in the head and shoulder area, this delicate zone is particularly well protected.

Kiddy K-fix Isofix connectors

With the Kiddy K-fix connectors your child safety seat can be easily connected to a cars' ISOFIX system. The system establishes a firm connection between the car body and the child safety seat (see vehicle type list).

Retraction mechanism

Due to the convenient retraction mechanism you can retract the K-fix connectors into the child seat quickly and easily. That's why the child safety seat can also be used in vehicles without ISOFIX system.

Use in aircraft

In the opinion of experts, the simple airplane lap belt may be a safety risk to small children in the event of turbulence or an emergency landing. This child safety car seat has been approved by TÜV Rheinland and the Federal Aviation Authority for use in aircraft.

Comfort features

Easy one-hand height and width adjustment

The unique adjustment mechanism allows for the height and width of the seat to be altered with just one squeeze of a hand on the back of the seat. Particularly easy fitting reduces the risk of incorrect installation and gives you peace of mind time after time.

Integrated diagonal seatbelt guide

The Smartfix has an enhanced seat belt guide features lever technology to make the fastening and unfastening of the seat belt even easier and safer.

3-stage leg extension

The Smartfix grows with your child from 15 kg to 36 kg. The three-stage leg extension ensures that the child sits safely and comfortably with the back and legs well supported no matter what their age, height or weight.

Comfortable Soft-Tex fabric

The Smartfix has extra soft padding to provide maximum comfort for the child. The Soft-Tex material helps regulate the child's temperature. It absorbs any moisture around the child; increases air circulation, and ensures a comfortable seating environment.

Durable cover

The seat covers come in many colours. They can be removed and machine washed at 30°C (gentle cycle).
