Your child's safety is our top priority. That's why there are no compromises when it comes to safety. The standards are more demanding than those of the current standard ECE R129 (i-Size). Dualfix M i-Size has been equipped with a large number of innovative safety features: for example the optimised side impact protection SICT inside, implemented by a special steel element inside the seat. Or the patented Pivot Link ISOFIX System. This ensures that your child is well protected in every accident, whether it is from the front, from the side or from the back. That's one thing you can rely on.
