The BeSafe iZi Flex Fix i-Size is the first booster seat launched that meets the newest safety regulation UN R129-02 (i-Size).

The BeSafe iZi Flex Fix i-Size is a high back booster seat for children from 100-150 cm which combines excellent safety features, high standards of comfort and flexibility that enables easy adjustment, quick installation and space for up to three people in one row on the back seats!

BeSafe welcomes the newest child car seat regulation UN R129-02 by presenting the first booster seat on the market that fully complies with the new safety requirements. Developed for real-life situations, this new BeSafe high back booster seat protects your child with safety features that even go beyond what is required by the regulation.

The latest regulation UN R129-02 puts significant new safety demands on high back booster seats. To provide maximum protection for the child, the BeSafe iZi Flex FIX i-Size is equipped with three layers of side impact protection and a headrest specifically shaped for the highest safety and comfort.

In addition to the dynamic flex-performance and Side Impact Protection (SIP) bumpers, the iZi Flex FIX i-Size also features BeSafe’s well proven innovation SIP+ (additional side impact protection). While the seat already passes the demanding approval tests of UN R129-02 without SIP+, this extra safety feature exceeds the regulations absorbing additional force by deforming like a car’s crumple zone and reducing side movement.

The high back booster also has a foldable lapbelt guider. Made of soft materials, this integrated solution helps with an optimal positioning of the lapbelt and also increases comfort. A fid-lock magnet makes opening and closing it easy. There are also lockable shoulderbelt guiders at the headrest ensuring that the seatbelt is always at the right height for the child.

The iZi Flex Fix i-Size is optimized for comfort with adjustable reclining positions for your child, as well as ease of installation for you. The height adjustment handles can be reached from both sides even when the child is seated and enable the iZi Flex FIX i-Size to grow with your child from 100 to 150 cm.

With its retractable ISOfix arms, this booster seat can be installed in a variety of vehicles. Being able to lock the ISOfix arms makes installation easy even if the ISOfix anchorages are difficult to reach deep within the vehicle upholstery.

iZi Flex FIX i-Size perfectly adjusts to your family’s needs. It enables you to fit up to three people in one row by simply detaching the SIP bumpers facing the inside of the car. More space – just as safe.

Thanks to its smart features for comfort, safety and space flexibility, the iZi Flex FIX i-Size won the prestigious Kind + Jugend Innovation Award in the category 'World of Travelling Kids'.
