For which age is this seat suitable?

This seat can be used from when the baby is born until approximately one year of age. However, please note that this is just an average value and does not limit or guarantee the usage time. You must stop using this seat when the height or weight limit is reached or the uppermost point of the baby’s head reaches the highest point of the seat. Ideally, you should look for toddler seats already some time before your baby has reached this point. Additionally, check how the shoulder belts are sitting on your baby’s shoulders. If the shoulder belts are not coming straight onto the shoulders anymore but are coming from below the shoulders when having the headrest/belts in the highest setting, then it’s time to change as well.
