Is it wrong to use the iZi Flex FIX i-Size without the removable SIPs?

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+ gives the child improved safety, because they significally 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.
