Can I buy, rent, borrow, loan or sell my used car seat?

Child Safety Seats (car seats) do not last forever.  The safety level of the seat may diminish without showing signs of weakness until it is involved in a vehicular crash.  The best practice for protecting your child is; new child, new seat.  This does not mean you have to go broke buying car seats.  Cost has nothing to do with the safety of the seat.  Here are some reasons for not using a second hand seat.  According to the National Highway Traffic and Safety Administration.

1. It may be a recalled seat.
2. The manufacturer’s labels are missing.
3. It may too old (over six years).
4. It may have been in a crash.
5. It may have broken or missing parts.
