The Solution Z i-Fix has been tested to the latest safety standards (UN R129/03) meaning it is now i-Size compliant and offers enhanced testing for side impacts. This seat is designed to grow with your child from 100 to 150 cm (approximately 4 to 12 years) and has 12 height settings that can be easily adjusted with one hand to perfectly fit your child. The reclining headrest ensures that your child’s head always remains in the safety zone, while the L.S.P. System Plus offers your child greater protection. The energy-absorbing shell also means that forces from a side impact collision are reduced by approximately 25%. The air ventilation system cools down the seat to a comfortable temperature, meaning your child will sit comfortably even on hotter days.
