I-Spark i-Size 2in1 is a modern solution for parents who not only value comprehensive safety, but also functionality. I-Spark i-Size is designed for children with a height of 100 to 150 cm (approx. 3.5 to 12 years) and complies with the i-Size safety standard R129. It was tested at a speed increased by up to 28%. This made it possible to test the breaking strength of the child seat shell more precisely, as it is subjected to 50% more kinetic energy. It can also be used without the backrest as a booster seat for older children with a height of 140-150 cm: Simply remove the backrest if your child no longer feels comfortable in the booster seat. The booster seat has been tested and meets the standards, including the i-Size safety standard. The booster seat has special safety systems that reinforce the construction and dissipate the energy generated in the event of a collision: H-Guard and SPS prevent the full force from being transferred to the little passenger's body. In addition, the headrest has a 10-stage height adjustment - you can adjust it with one hand.
