About this site

CarSeatExpiration answers one question: is this seat past the maker's stated useful life, and where is the date that settles it? It exists because the answer lives in a label on the shell and a sentence in a manual, and finding both should not take twenty browser tabs.

Where the figures come from

Every useful-life figure on this site is read from the manufacturer's own statement — a published support page or the seat's instruction manual — quoted verbatim where it appears, with a link and the date we last read it. Where a maker doesn't publish a figure, the page says so and points at the maker's own support channels instead of guessing.

Federal law requires the month and year of manufacture on the label. Expiration is the manufacturer’s own policy, not a federal rule.

What this site deliberately does not do

• It issues no safety verdicts. It reports what the maker states; the label on your seat is authoritative.
• It never asserts a seat has no recalls — NHTSA's lookup is the record.
• It carries no installation or harness-fitting advice. That belongs with a certified child passenger safety technician.
