Choose the Cybex Solution B2 i-Fix child seat and you get a great combination of safety, comfort and ease of use, tested according to the UN R129/03 standard. The Isofix system helps you to install the child seat correctly and safely right from the start. No matter how fast your child grows, with the 12-position height-adjustable headrest you can always adjust the seat precisely and with just one hand. The linear side impact protection reduces the side impact forces in the event of a side impact and thus ensures greater safety on the road. There is also a cup holder so that your child has everything they need within reach while travelling.
