how long can you use a car seat for

Car seats aren't exactly the 'buy once, use forever' kind of deal. Typically, they expire after about 6 to 10 years due to wear and tear, plus evolving safety standards. You should also replace a car seat if it’s been in a moderate to severe crash, regardless of age.

Always check the manufacturer’s label for the exact expiry date and heed their warnings—old or damaged seats might as well be glorified lawn chairs. And remember, kids outgrow seats by weight and height limits, so switch to the next stage seat accordingly.
