Why Small Cars Need the Right Car Seat

The American Academy of Pediatrics (AAP) says safety comes first, and these seats deliver that in spades while keeping things snug. We’ve focused on narrow designs, easy installs, and crash-tested reliability to give you peace of mind in your small car baby safety setup.
