Frequently Asked Questions
Where do I find the manufacture date?
It's usually printed or stamped on a sticker on the bottom or back of the car seat, often near the model number and serial number.
Why do car seats expire?
Plastic components degrade over time with heat and UV exposure, and safety standards and testing methods improve, so manufacturers set expiration dates for safety.
Does the expiration date change if the seat was never used?
No, expiration is based on manufacture date, not first use, since materials degrade regardless of use.
