Certified Safety – UN R129 (i-Size / R129-02)

Flex Fix 2 i-Size complies with the latest European safety regulation UN R129, ensuring:

Improved side impact testing standards

Compatibility with i-Size approved vehicles

Height-based classification (100–150 cm)

Designed exclusively for forward-facing installation, it provides reliable protection throughout the later childhood years.

Advanced Side Impact Protection System

Safety is the core focus of the Flex Fix 2 i-Size.

SIP+ – Additional Side Impact Protection

The removable SIP+ module attaches to the side of the seat facing the car door to provide enhanced protection in the event of a side collision.

When space is limited — for example, when installing three car seats side-by-side — the inner SIP+ can be removed to reduce width without compromising overall functionality.

Innovative V-Shaped Headrest

Designed to provide optimal head support and visibility

Features flexible zones engineered to help absorb energy during side impacts

Belt Positioning Guidance

Colour indicators assist parents in verifying correct vehicle seat belt positioning across the child’s shoulder and hips, promoting both safety and comfort.

Grows with Your Child – 14 Height Positions

The Flex Fix 2 i-Size adapts precisely to your child’s growth thanks to:

14 adjustable headrest positions

Easy, smooth height adjustment mechanism

Extended usability from approx. 4 to 12 years

This makes it a long-term investment in safe and comfortable travel.

Comfort for Everyday & Long Journeys

Whether it’s the school run or long-distance travel, comfort remains a priority.

2 recline positions for a more relaxed seating posture

Ergonomically shaped seat base balancing support and freedom of movement

Soft, hypoallergenic fabrics

Removable and machine-washable cover

The design promotes an upright yet relaxed sitting position, ideal for growing children.

Flexible Installation Options

The Flex Fix 2 i-Size can be installed:

With ISOFIX connectors + 3-point vehicle seat belt

Or using the vehicle’s 3-point seat belt alone, depending on car configuration

This ensures broad vehicle compatibility while maintaining stability and ease of use.
