But what makes a car seat an “all-in-one”?
This type of car seat combines a harness and a headrest into one piece, so you don’t have to adjust the fit based on your child’s size. They often have longer harnesses, which are more secure than the more standard 6-8 inches of adjustment. And they tend to be lighter than some other types of seats because they have fewer components.
Read on to find the best all-in-one car seats for your child.
