The Axkid One 3 is designed for children from birth up to 7 years old (61-125cm height, up to 23kg weight). It's one of the few extended rear-facing car seats that can safely accommodate children for this entire age range.
Yes, the Axkid One 3 can be used from birth with the included infant insert for children between 61-105cm. For newborns, you may want to consider the One + 3 upgrade which is specifically designed for use from birth.
The Swedish Plus Test is the world's toughest voluntary crash test for car seats. It uses higher impact speeds and shorter braking distances than standard EU testing, specifically measuring neck forces that could cause life-threatening injuries. BeSafe Stretch has passed this rigorous test, ensuring your child won't experience dangerous neck forces during a frontal collision. Only seats that pass this test receive Plus certification - a gold standard in car seat safety.
I needed an extended rear-facing car seat for my grandson and chose this one because his parents had previously bought an equivalent car seat from Little Peas. We were able to fit the seat (using ISOFIX brackets) easily and my grandson seems very comfortable, as well as safe, in it. The service from Little Peas was excellent in every respect.
