Car seats typically expire 6 to 10 years after their manufacture date, with most manufacturers recommending replacement after this period due to material degradation and evolving safety standards. The expiration date is often stamped on the seat itself, so always check the label. This isn't just a suggestion—it's a critical safety measure, as plastics and foam can weaken over time, reducing the seat's ability to protect your child in a crash.
The primary reason for expiration is the breakdown of materials like EPS foam (expanded polystyrene foam, which absorbs impact energy) and plastic components from exposure to heat, sunlight, and temperature fluctuations. Additionally, safety regulations improve over the years; an older seat might not meet current crash-test standards. For instance, the National Highway Traffic Safety Administration (NHTSA) advises against using expired seats because they may not perform as intended during a collision.
To ensure safety, register your car seat with the manufacturer to receive recall notices, and never buy a used seat without verifying its expiration date and history. If you're unsure, contact the manufacturer directly—they can provide specific guidance based on the model.
Here's a table with expiration data from major car seat brands to illustrate the variability:
| Brand | Typical Expiration Period (Years) | Notes |
|---|---|---|
| Graco | 6-10 | Varies by model; check label |
| Britax | 6-10 | Often 7 years for infant seats |
| Chicco | 6-8 | KeyFit models usually 6 years |
| Evenflo | 6-10 | Some convertible seats last 10 years |
| Maxi-Cosi | 6-10 | European brands may differ |
| Safety 1st | 6-8 | Budget-friendly options |
| Clek | 7-10 | Higher-end, longer lifespan |
| Diono | 8-10 | Steel frame models |
| UPPAbaby | 6-7 | Infant seats on shorter side |
| Cybex | 6-8 | German engineering focus |
Ultimately, replacing an expired car seat is a small price for your child's safety. If your seat is near its expiration, start shopping for a new one that meets the latest standards.

As a parent who's been through this with two kids, I can tell you that car seats do expire—usually around 6 to 10 years. I learned the hard way when I found an old seat in the attic and saw the date had passed. It's not just about rules; the plastic gets brittle over time. Always look for the stamp on the seat; it's your best bet to keep your little one safe without overcomplicating things.
