How To Quickly Narrow Down Car Seat Options For 40 Lbs And Up

Start with your child’s weight and height, not just their age. Check if you need a seat that transitions as your child grows, or if a booster is enough. Consider how often you’ll move the seat between cars. Look at the space in your vehicle’s back seat, especially if you have more than one child.

Think about how easy it is to clean the seat covers after spills. Most people miss checking the headrest adjustment—make sure it’s simple to use as your child grows.

The 30-second Checklist For Busy Parents
