Car seats are an essential safety measure for young children in vehicles. However, not all cars are equally capable of accommodating car seats. To determine the worst performers in this area, Cars.com conducted tests on 56 car models. The evaluation included factors such as the latches, rear-facing infant seats, rear-facing convertible seats, forward-facing convertible seats, high-back booster seats, and third-row access (if applicable).

Cars.com assigned letter grades to the vehicles in their study. To compare the results, we converted these grades to numbers and calculated the average figures. Similar to a school GPA, where a 4.0 represents straight A’s, the closer a car’s score is to 4.0, the better it performs in accommodating car seats.
