Das Kopfteil kann in der Höhe verstellt werden und hat auf jeder Seite einen Becher/Flaschenhalter. Das Kind wird durch den normalen Gurt, der oben im Schulterbereich durch eine Gurt-Führung und über den Hüftbereich geführt wird, fixiert. Der Sitz ist leicht doch durch den Gurt wird er sehr gut befestigt.Bin sehr zufrieden damit ### ⭐⭐⭐⭐⭐ Aisé à monter, à transporter, et confortable, combo gagnant ! *by on Reviewed in France 16 September 2025* Siège rehausseur acheté pour mon fils qui fait 1 m 38.Le montage est intuitif, le siège est léger à transporter et dispose d'un appui-tête facilement réglable grâce à une poignée.
