The 9 Best Car Seats, According to Experts and Parents

RideSafer Vest Travel Car Seat ($179) and TravelSmarter Booster Seat ($89)

The Travel Vest is a lightweight and safe option for travel. It fits in a compact bag and can be tethered to your car for upper body restraint. It's also the most slim car seat option I've tested and makes three across possible.

The Booster Seat weights only one pound and can be used with or without the vest. It's recommended for children starting at age 4 and can be used for kids who weigh 40 to 100 pounds. This streamlined option is also ideal if need a portable option between caregivers' cars.
