This seat is really good and I toured the seats and their opinions on the internet and I took this one for my 2 daughters and it is really perfect it envelops the child well, so it's soft comfortable, can tilt and the headrest is easily adjusted when sleeping and his head did not fall. Especially the attachment of the seat is simple and well secure with the belt blocking system ... In short it is perfect for me my girls now 2 years (10kg) and 3 and a half years (12 kg) and are at ease in
