We at Axkid recommend as small an inclination of the car seat as possible, provided that the child can sit upright by itself without the head falling forward. All children are different and the inclination of the car seat must always be adapted to the child’s needs. The recommended angle for small children is about 30-35 degrees. A suitable angle for older children is between 15-25 degrees. Depending on the car seat model, there are different numbers of tilt positions and if you feel that you need more tilt than what the tilt control offers, you can buy a tilt wedge from one of our retailers » or at www.axkid.com »
Here is a video of how the wedge should be used.
