How Long Are Car Seats Good for Before They Expire?

Depending on the brand and model, car seats are good for six to 10 years from the date of manufacture. Expect the majority of car seats—even the best ones—to expire after about six years. Those made with steel-reinforced frames can last up to 10.

What is the lifespan of a car seat?

The lifespan of a car seat varies both by brand and type of car seat. Rear-facing seats, the kind you use to bring your infant home from the hospital, have shorter shelf lives while convertible and booster seats last a bit longer. So while a rear-facing Evenflo car seat will last you six years, a booster seat from Chicco will last closer to eight.

When to upgrade your car seat

Rear-facing car seats 

  • Usually last about six years
  • Fit infants and toddlers up to 35 lbs. and 32 in. tall

Convertible seats

  • Last between six and 10 years
  • Fit kids up to 60 lbs. and 50 in. tall

Booster seats

  • Last between six and 10 years
  • Fit children up to 100 lbs. and 57 in. tall

How long do infant car seats last?

Rear-facing car seats typically last for six years. Infants and toddlers should use a rear-facing seat until they reach the maximum height or weight limit—usually around 40 pounds and 32 inches respectively—which varies by brand.1

Because convertible car seats typically convert either from front-facing to booster or from rear-facing to front-facing to booster, they have a longer shelf life. Most convertible car seats expire after eight to 10 years, but weight and height restrictions vary.

    Still, you can expect most convertible car seats to cover roughly the same ground. If a convertible seat has a rear-facing mode, you can use it until your baby reaches 40–50 pounds and 32 inches tall. Once you convert it to forward-facing, you can use the convertible car seat for a toddler up to roughly 60 pounds and 50 inches tall. And as a booster, expect to fit a child up to 100 pounds and 57 inches tall.

    How long do booster seats last?

    Backless and belt-positioning booster seats last for about 10 years. Use one if your child is 40–57 inches tall or 40–100 pounds.

      Do car seats actually expire?

      In short, yes. To figure out when a car seat expires, reference the seat’s owner’s manual for its lifespan and find the manufacturer’s label on either the side or base. Some seats have the date of manufacture, others list an actual expiration date, and some car seats have both.

      If you no longer have your owner’s manual on hand or if you don’t remember when it expires, don’t worry. You can write down the seat’s model number and look up the lifespan online on the brand’s website or call the manufacturer to find out when your car seat expires.

      Why do car seats expire?

      Car seats expire for several reasons:

      • Wear and tear
      • Improved standards
      • Replacements and recalls
      Wear and tear

      Car seats are typically made of plastic, which degrades over time, especially when exposed to extreme temperatures. And since these child restraints stay inside your vehicle, they’re often exposed to both very warm and very cold temperatures. Depending on where you live, the temperature inside your vehicle can range from -50°F to 140°F.2

      For an easy comparison, consider what a plastic patio set looks like after being exposed to sun, heat, and cold temperatures year after year. It’s brittle and prone to breaking. The same goes for your car seat, which holds much more precious cargo.

      Improved safety standards

      Technology is constantly improving and so are car seats. A seven-year-old convertible seat may look like it’s in good condition but it won’t be fit with the latest technology—like energy-absorbing foam or steel frames—to save your child’s life in a crash.

      If you’re curious about technology’s role in car seats, consider the LATCH system. LATCH, an advanced technology that makes it easier to install and secure car seats, is required on car seats and most vehicles, but it wasn’t standard until 2002.3

      Replacements and recalls

      It’s good practice to register your car seat with its manufacturer after your purchase so you can keep up with any recalls. If you’re using a used or expired seat, you risk that it may have been part of a recall that you don’t know about.

      Plus, parts are bound to go missing when you’re converting your 3-in-1 car seat from rear-facing to forward-facing to a booster. If your car seat is creeping towards its expiration date, you may not be able to get replacement parts after that date has come and gone.

      Can you reuse a car seat?

      If your child has outgrown their car seat but the seat is in good condition with all parts intact, hasn’t expired, and hasn’t been recalled, you can reuse it or pass it on. But if the seat is damaged in any way or if it’s been in a car accident, don’t reuse it.

      We also recommend to avoid purchasing used seats online. You have no way of knowing if the seat was involved in a severe crash or if any parts are missing.

      If you’re looking for something to do with an expired or damaged seat, you have a few options.

      What to do with an expired car seat

      Tempting though it may be to let an expired or damaged car seat collect dust in your garage or to dump it on the corner for sanitation to deal with, there are other options.

      Stores like Target and Walmart offer annual trade-in events where you can swap an old car seat for a coupon or gift card. And although most recycling centers don’t accept car seats, you can check to see if any recycling locations in your state accept car seats.

      If you opt to throw it out, there are a few steps you should take to make sure someone else doesn’t get their hands on an unsafe seat:4

      1. Use scissors to cut off the seat’s fabric, foam padding, and safety or harness straps.
      2. Use a screwdriver to remove as much metal as you can. Afterwards, remove the car seat cover and any padding underneath.
      3. Throw away unrecyclable bits like fabric, straps, and small plastic or metal pieces.
      4. Use a permanent marker to mark the remaining plastic unsafe and cross out the expiration date.
      5. Recycle the plastic body of the car seat and any remaining metal parts.



      While car seats can last anywhere between six and 10 years, it’s important to retire them once they’re expired to ensure your children’s safety. We recommend keeping up with your child safety seat’s expiration date—and replacing as needed—to keep your little ones safe.
