No matter how well your child’s car seat functions, it still has an expiry date provided by the manufacturer.

In this article we will cover this topic and other child safety-related tips regarding car seat safety. You should not use the car seat after it reaches the expiry date and here’s why…

Do Car Seats Really Expire?

The short answer is – yes they really do! Cars seat materials tend to break down over time resulting in a loss of structural integrity. If you are like me, you would never want to risk the safety of your little one by trying to get another year or two out of an expired car seat.

Here are some reasons why car seats expire:

  • Extremely cold and extremely hot temperatures truncate seat’s plastic components and make it brittle, although plastic deteriorates over time either way,
  • Seats with steel frames corrode due to spills,
  • Moving pieces are so easy to get lost (and damn hard to find and replace), which reduces the seat’s safe function dramatically.

Where Do I Find The Expiry Date?

It all depends on the manufacturer and the design. Still, the average lifespan of a regular car seat never goes under 4 and beyond 10 years. Luckily, the expiry  dates are either embossed on the unit or specified in the product manual.

Here are some of the most popular car seat brands and their expiry details:

  • Chicco – up to 6 years from date of manufacture.
  • Britax – infant models manufactured after June 2020 up to 6 years and convertibles up to 7 years
  • Evenflo – up to 6 years from date of manufacture. Some newer models up to 8 years
  • Graco – up to 6 to 10 years from date of manufacture. Some newer models may have a longer shelf life, check product manual to verify.
  • Diono – up to 10 years from date of purchase
  • Peg Perego – After November 2015 car seats expire after 10 years. Booster Seats – Before October 2015, car seats expire after 7 years.
  • Doona – Refer to the sticker at the bottom of the Doona car seat to determine expiry date. For most models discontinue the use of a Doona car seat after 6 years from the date of manufacture.

How Often Do You Change Car Seats?
