Choosing a car seat, safely

Safety essentials: Follow your specific seat's instruction manual — height as well as weight limits apply in every mode. Use the top tether for every forward-facing installation. Register your seat with the manufacturer so recall notices reach you, and check the NHTSA recall lookup (nhtsa.gov/recalls) and CPSC database for your exact model before buying new or used. Never use a seat past its expiration date or after any crash, and never buy a used seat with unknown history.
