The BeSafe iZi Modular X1 i-Size is the upgraded version of the iZi Modular i-Size toddler seat and now newly features the Dynamic Force Absorber™ - an innovative construction that works like a trampoline and carefully protects the child’s most vulnerable body parts in an accident. On top of that, iZi Modular X1 i-Size not only features Side Impact Protection in its side wings, but also additional Side Impact Protection (SIP+) that is added to the side facing the car door. The new construction of this SIP+ allows you to easily slide it onto the seat shell. iZi Modular X1 i-Size is approved to the latest safety regulation UN R129 (i-Size)
