iZi Flex Fix i-size Starting from € 349,00

The first i-Size car seat for big kids which fits up to 3 children in a row!
The BeSafe iZi Flex FIX i-Size is the first i-Size high back booster seat for big kids, combining excellent safety features, high standards of comfort and flexible solutions to enable easy adjustments and installation. You can fit up to three children in a single row, by simply removing both side bumpers from the middle seat – more space – just as safe.
To provide maximum safety for the child, the BeSafe Flex FIX i-Size is equipped with extra Side Impact Protection (SIP+) on the outer shell of the seat. The foldable lap belt guider was inspired by the BeSafe pregnancy belt. This integrated solution prevents submarining as it guarantees correct positioning of the lap belt during a crash.
NEW: i-Size car seats with Peak Mesh, a knitted 3D-fabric with open structure which creates air layers. These layers increase breathability, guiding moisture away from the child. The result is reduced heat absorption and increased comfort.

Write a reviewMijn dochter zit heel graag in de autostoel.
Makkelijk te installeren. Vlotte manier om de autostoel aan te passen aan een groeiend kind. Extra beveiliging tussen de benen kan mijn dochter niet zelf opendoen, wat handig is.

Zeer eenvoudig te installeren en in gebruik te nemen !
FAQ
This seat has already passed the demanding crash test criteria of the UN R129 regulation without the SIP+, so that the SIP+ is not required to be used. If it is possible to fit it in-between the seat and vehicle door, we however recommend you to use it for even better side impact protection.
If there is not enough space in your vehicle to fit the SIP+ in-between the seat and the vehicle door, you do not need to use the SIP+. As the main function of the SIP+ is to reduce the distance between the seat and the vehicle door, you have no safety disadvantage by not being able to fit the SIP+, as you already have a reduced distance in your situation.
No, the SIP+ module is only usefull, when used between a vehcile door and the seat.
By being a separate part, you can easily move the SIP+ from side to side, so that you can use it no matter where you position the child seat in the car.
SIP+ reduces the distance between the seat and the door of the vehicle. In this way the seat and the door will meet each other earlier in a side impact, resulting in less acceleration and absorption of the energy over a longer distance and earlier during the impact. SIP+ can lead to a reduction of 20% of the head acceleration values.
Yes, the BeSafe iZi Flex Fix i-Size can absolutely be used without the ISOfix installed. But when ISOfix is available, you can use the ISOfix for securing the booster seat perfectly, even without a child sitting in it.
The lapbelt guider is optional to use as it only indirectly impacts the child’s safety. A child who is correctly placed in the seat travels safely with or without using it. However BeSafe’s recommendation is to always use it as we always recommend to use all precautions to minimize any safety risks.
The iZi Flex Fix i-Size offers generous possibilities for adjustments, to fit children from 100 to 150 cm in height. The booster seat is also easily adjusted to the child’s height by use of one of the handles – there is one handle on each side so you can adjust it from any side. This can be done with the child sitting in the seat, so you can adjust it accurately and quickly. The headrest should be adjusted so the vehicle seat belt is guided 90 degrees through the shoulder belt guiders, over the child’s shoulders. You can also adjust the reclining feature of the iZi Flex Fix i-Size for a perfect sitting position – this must be done before you put on the seat belt, in order to avoid slack in the seat belt. The seat belt should be tightened properly, and the lap belt guider will put the seat belt in the right position over the child’s body.
In BeSafe, we always look for the best solutions and we design our car seats for real-life situations – not only for pre-defined tests in a laboratory. Our experiences and tests have shown that the SIPs and the SIP+ give the child improved safety because they significantly reduce the load on the child if a side impact should occur. Although the BeSafe iZi Flex Fix i-Size is approved without them, you should always aim for the best safety for yourself and for your child. Therefore, we recommend that you always use the removable SIPs and SIP+ on the iZi Flex Fix i-Size towards the car door, as long as there is space available.
The iZi Flex Fix i-Size is approved in UN R129-02 without any additional SIP+ or SIP bumpers (at the inside of the vehicle). The SIP bumpers and the SIP+ improve the side impact performance and should always be used at the door side of the vehicle. Only when a third CRS is used in the middle position of the vehicle, may the SIP bumper be taken off, but only at the inside of the vehicle and not at the door-side. The possibility to install three iZi Flex Fix i-Size seats in a row depends mainly on the car, and where the ISOfix anchorages are mounted in the seat of the car. If possible, use ISOfix for all three of the seats; this is normally only feasible in a vehicle with three separate vehicle seats in the second row. If there is less space, or if there are only two ISOfix anchorages placed a bit out of line, you can use the BeSafe iZi Flex Fix i-Size seats in combination with the vehicle belts only.
When installing an iZi Flex Fix i-Size on an outer vehicle seat, you can take the inner SIP bumper off in order to be able to fit several seats/people next to each other. When installing an iZi Flex Fix i-Size in the middle position in the vehicle, both SIP bumpers can be taken off if you would like to place other seats/people next to the iZi Flex Fix i-Size on both sides. When installing an iZi Flex Fix i-Size in the middle position in the vehicle but are only placing another seat/person next to it on one side, we recommend you to keep the other SIP bumper on the iZi Flex Fix i-Size.
In the UN R129 regulation, the classification has changed from kilograms to centimetres, since parents often know more accurately how tall their child is. This makes it easier to choose the right (and safest) seat.
Yes, in order to be able to facilitate several seats or people next to each other in a vehicle, the SIP bumpers of iZi Flex (S) Fix can be detached. However, we recommend you to always keep the outer SIP bumper facing the vehicle door attached when having iZi Flex (S) Fix installed on an outer vehicle seat position for an optimal safety performance. In addition, we recommend you to also attach the SIP+ onto the SIP bumper facing the vehicle door if there is space available for additional side impact protection.
The iZi Flex S Fix is a slightly scaled-down version of the premium iZi Flex Fix i-Size that was launched in March 2018. iZi Flex Fix i-Size has 4 features that iZi Flex S Fix does not have: the SIP+, PAD+, adjustable recline positions and the lap belt guider. All other aspects, e.g. the space-adjustability or the seat dimensions, are identical between both seats.
The BeSafe iZi Flex FIX i-Size is certified with and without the usage of the ISOfix anchorage. If available, it’s always better to use the ISOfix anchorage since it secures the seat better when there is no child in the seat (and the vehicle belt is not used to secure the seat without child). The safety performance is almost the same with or without the usage of the ISOfix anchorage.
