Car seats are one of the most important safety products you'll ever use for your child. Did you know they typically have a lifespan of 6 – 10 years, depending on the brand and model?
While it might seem surprising that something so solid and well-built would have an expiry date, there are good reasons behind it.
Why Do Car Seats Expire?
- Wear and Tear: Over time, materials like plastic can become brittle and weaken, especially after sitting in a hot vehicle exposed to harsh UV rays. Even if a seat looks fine on the outside, internal components may have deteriorated, and this could potentially compromise the seat's effectiveness.
- Changing Safety Standards: Car seat technology and safety regulations evolve. An expired seat may not meet the latest standards or be compatible with newer vehicle designs.
Considering a Second-Hand Car Seat?
If you're thinking about buying - or accepting - a second-hand car seat, checking the expiry date should be your first step.
Additionally, it’s important to:
- Ensure it hasn’t been in a crash: Car seats involved in an accident may have hidden damage and should not be reused.
- Make sure all parts are included: Without the original manual and components, proper installation may not be possible.
- The seat must also have its original certification label to certify it complies with one of New Zealand’s approved safety standards - NZ/AU, ECE, or US displaying yellow S sticker. Learn more
Where to Find Expiry Information
The expiry will either be from Date of Manufacture or from Date of Purchase (with a receipt) – depending on the brand. To check your seat, check the car seat expiry list here.
Car seats generally have a label or stamped date on the shell that indicates the date of manufacture.
This example above shows the date embossed on the shell – Date of Manufacture 4 June 2022
In this example the date is found stamped on the harness clips - Date of Manufacture August 2023
In this case it’s a sticker – Date of Manufacture 18 July 2024
The Bottom Line
Your child’s safety is too important to leave to chance. Always check a car seat’s expiry before use - especially if you’re considering a second-hand one. When in doubt, it’s best to invest in a new, up-to-date seat that meets all current safety standards.
