ADAC Tested means that the seat has been independently assessed by the German Automobile Club ADAC. This test is considered one of the most stringent in Europe and evaluates not only frontal and side impact safety, but also ease of installation, ergonomics, pollutant content and child comfort. The results are given on a point scale, where a lower value means a better result. Seats with a very good ADAC rating are among the safest on the market and are often recommended by experts and consumer organisations.
