Car seat expiration dates by brand: all 14 compared
Useful life ranges from 6 to 12 years depending on the brand and even the model line. The full comparison, plus who is most and least generous.
Car seat useful life varies from 6 to 12 years depending on the brand and model. Graco allows 10 years on most current seats, Chicco 6 to 8, Britax 6 to 10 by model line, and Clek a flat 9. Peg Perego's newest boosters reach 12 years, the longest of any major brand.
What is the useful life for each brand?
The table below reflects manufacturer statements as of mid 2026, the same manuals and support pages NHTSA defers to on useful life. Where a brand varies by model, the range and the main rule are noted. Always confirm against the label on your own seat, because policies change between model years and older seats keep their original, often shorter, lifespans.
| Brand | Useful life | Notes by model |
|---|---|---|
| Baby Trend | 6 years | Most seats 6 years from manufacture; a few models such as the Trooper 3-in-1 reach 7 |
| Britax | 6 to 10 years | Infant seats 6; most convertibles 7; ClickTight convertibles 10; Harness-2-Booster 9 |
| Chicco | 6 to 8 years | KeyFit infant seats 6; convertibles and boosters 8 |
| Clek | 9 years | Flat 9 years across all seats, the simplest policy of any brand |
| Cosco | 6 to 10 years | Seats made after December 2013 generally 10; earlier seats 6 to 8 |
| Cybex | 8 to 10 years | Sirona M 8; Sirona S 10; check the sticker on the base of each model |
| Diono | 6 to 10 years | Radian-family convertibles 10 as boosters, 8 in harness mode; others vary |
| Evenflo | 6 to 8 years | Most seats 6; Symphony and some newer all-in-ones 8 |
| Graco | 7 to 10 years | 10 for boosters and seats with steel-reinforced belt paths, which covers most current models; 7 for older plastic-reinforced harnessed seats |
| Maxi-Cosi | 6 to 8 years | Varies by model; DOM molded into the shell or base |
| Nuna | 7 to 10 years | PIPA infant seats 7; RAVA convertible 10 |
| Peg Perego | 7 to 12 years | Infant seats 7; newer boosters up to 12, the longest on the market |
| Safety 1st | 6 to 10 years | Varies by model; post-2013 seats mostly 8 to 10 |
| UPPAbaby | 7 years | MESA infant seats 7 from manufacture; check labels on KNOX and ALTA |
Which brands give you the longest and shortest life?
At the generous end, Peg Perego's 12-year boosters and the 10-year policies from Graco, Britax ClickTight, Diono Radian, Cybex Sirona S and Nuna RAVA stand out. A 10-year convertible bought at birth can genuinely be the only harnessed seat a child ever needs.
At the short end, Baby Trend's 6 years and the 6-year infant seats from Britax and Chicco are the ones to watch, though 6 years on an infant seat matters less in practice: babies outgrow them in 12 to 18 months, so the limit mostly bites on second children and hand-me-downs. Where a short lifespan really stings is convertibles and all-in-ones marketed as "10 years of use" that only carry 8 years of certified life. The marketing number and the label number are not always the same number.
Why do the numbers vary so much between brands?
Three reasons. Materials and construction differ: steel-reinforced frames age differently from pure polypropylene shells, which is exactly why Graco splits its policy along that line. Testing budgets differ: certifying a longer life means validating aged samples, and not every manufacturer invests in that for every model. And risk posture differs: a flat 9, like Clek's, trades some nuance for a rule no parent can misread. None of the variation means a 6-year seat is built worse than a 10-year seat; it means the manufacturer only stands behind it for 6. The reasons seats age at all, plastic fatigue, standards updates, recall reach, are covered in why car seats expire.
How do I check my own seat against this table?
Find the date of manufacture on the shell label, then apply your brand's number from the table above. If the label is confusing, our label guide decodes the stickers, stamps and date wheels each brand uses. Or skip the manual math: the SeatCheck checker takes the brand and DOM and returns the expiry date with the manufacturer's rule cited. If the answer is "already expired," trade-in events and recycling options are collected in our disposal guide.
