I am very happy to sit with both. They are used in cars with and without Isofix because the connectors are simply folded away.
Both children can put themselves in the meantime (4 + 6 years) in Skoda Octavia.
Easy to clean, comfortable and quite easy to install. We need the seats every 2nd weekend rebuild from Skoda in the Mini of the Father.
No Problem. The height of the headrest is changed fix for any visitor children smaller or larger.
Conclusion: Buy recommendation!
