Fantastic seat for 15kg and over
Been using this for a while now and it's lovely for the price. It'not too bulky like some are, the back comes off when it's time to move to just the booster seat, and it has 2 cup holders that can be pushed in when not in use. The booster sits nicely in the back seat, and just about fits in the back with 2 other booster seats, as long as they're not too bulky. Seat belt fits into a clip on the back to help keep the cross body part secure without sitting on the child's neck. Note: This is not a seat with a 3 point harness. It is the next step up from those seats. We use weight to move up to the next stage, it is my understanding that the weight to move up is from a 3 point harness fully secured base, to one like this is 15kg.

Bra för pengarna
Köpte till styvsonens barn. En alldeles utmärkt produkt som dessutom kan användas när barnets längd förändras. Barnet i fråga tycker att stolen är bekväm, så då ger det såklart extra stjärna

Leggero, comodo e molto pratico per l’uso quotidiano
Seggiolino davvero pratico e ben fatto, soprattutto per chi cerca una soluzione semplice ma comoda per il bambino. Una delle cose che ho apprezzato di più è la leggerezza: si sposta facilmente da un’auto all’altra senza fatica. La seduta è spaziosa e il bambino viaggia comodamente anche durante tragitti più lunghi. I materiali sembrano di buona qualità e l’imbottitura offre un buon comfort senza risultare troppo rigida. Anche l’installazione è risultata semplice e intuitiva, senza dover perdere troppo tempo con regolazioni complicate. Il design è essenziale ma funzionale e nel complesso dà una buona sensazione di sicurezza e stabilità. Ottimo rapporto qualità-prezzo, consigliato per praticità e comfort.

Perfect
My kids are already 4 and 5 so the eggshells were not comfortable for them. This seats are perfect, comfortable, easy to keep clean. Will stay with us many years for sure.

Günstig und trotzdem stabil und zuverlässig
Preiswert und trotzdem sehr gut. 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
