You can buy second-hand car seats from a variety of sources, including major online marketplaces, local brick-and-mortar retailers with trade-in programs, and community-based platforms. However, the most critical factor isn't where you buy, but ensuring the seat's complete history is known and it meets all current safety standards. Purchasing a used car seat carries significant risks, as it may have been in an unreported accident, have expired, or have missing parts.
Your safest bets are established retailers like Target or Walmart that often host car seat trade-in events. During these events, you can bring an old seat and receive a discount coupon for a new one. The traded-in seats are responsibly recycled, and you get a brand-new, guaranteed-safe seat at a reduced price. This is often a better value than buying a used one of uncertain quality.
For peer-to-peer purchases, Facebook Marketplace and Craigslist are common, but require extreme diligence. Only consider a seat if the seller is the original owner and can provide proof of purchase and a full history. Goodwill or other thrift stores are generally not recommended, as they cannot verify a seat's safety.
Always perform a thorough inspection before any purchase. Check for the manufacturer's label to confirm the manufacture date and that it has not expired (typically 6-10 years from manufacture). Look for the model number and ensure the recall list on the NHTSA website is clear. Inspect the plastic shell for cracks, the harness for fraying, and ensure all parts are present.
