Car Seat Expiration: How Long Are Car Seats Good For?

A car seat is not designed to last forever. Over time, materials can degrade, components can wear out, and safety standards may change. That is why checking the car seat expiration date is an important step before continuing to use an older seat or purchasing a secondhand car seat.

So, how long are car seats good for, where can you find the expiration date, and should you continue using an expired car seat? Here is what parents need to know.

What Is Car Seat Expiration?

Car seat expiration refers to the point at which the manufacturer determines that a child car seat has reached the end of its recommended service life. The expiration date is typically calculated from the Date of Manufacture (DOM), not from the date the car seat was purchased or first used.

For example, if a car seat has an eight-year lifespan and was manufactured in June 2026, its expected expiration date would be around June 2034, unless the manufacturer specifies otherwise.

It is important not to apply one general expiration rule to every car seat. Different brands and models may have different recommended lifespans.

How Long Are Car Seats Good For?

Most car seats on the market are designed to be used for approximately 6 to 10 years from the date of manufacture. However, this is only a common range and does not apply to every product.

The actual lifespan of a car seat may depend on:

  • The seat’s design and materials
  • The type of car seat
  • The manufacturer’s guidelines
  • The specific model or version
  • How the seat is used and stored

Some convertible car seats or booster seats may have a longer usable life than certain infant car seats.

To determine exactly how long a car seat is good for, parents should check the label on the seat or refer to the owner’s manual for that specific model.

Why Do Car Seats Expire?

A car seat expiration date is not simply a deadline intended to encourage consumers to buy a new seat. There are several practical reasons why child safety restraints have a limited service life.

Materials Can Degrade Over Time

Car seats are regularly exposed to changing temperatures inside a vehicle. In the summer, the cabin can become extremely hot, while winter temperatures can drop significantly.

Over the years, plastic, padding, harness straps, and other components may age or wear down. Not all of these changes are visible to the eye.

Components Can Wear Out

Buckles, harnesses, adjustment mechanisms, ISOFIX/LATCH connectors, and other moving parts may be used hundreds or even thousands of times during the life of a car seat.

Even if the seat still looks good on the outside, some components may no longer perform the same way they did when the product was new.

Safety Technology and Standards Continue to Evolve

Car seats are designed to meet the technical and safety requirements in effect when they are developed. Over time, product designs, testing methods, and safety standards may be updated.

Replacing a very old car seat can also give parents access to newer safety features and updated child-restraint technology.

How to Check a Car Seat Expiration Date

Not every car seat displays the words “Expiration Date” in an obvious location. Parents can use the following steps to determine when a seat expires.

1. Find the Date of Manufacture Label

Check the back, underside, or base of the car seat.

The product label may include information such as:

  • Date of Manufacture
  • Manufactured Date
  • Model Number
  • Serial Number
  • Expiration Date
  • Do Not Use After

If the manufacturer provides a specific expiration date, follow that date.

2. Check the Owner’s Manual

If the car seat only lists the date of manufacture, check the owner’s manual for the recommended service life of that particular model.

For example:

Date of Manufacture + Recommended Lifespan = Estimated Expiration Date

If a car seat was manufactured in September 2026 and has a seven-year lifespan, it would generally expire around September 2033.

3. Check Information for the Exact Model

Do not use the expiration period of another model from the same brand to estimate the lifespan of your seat.

Even within the same manufacturer, infant car seats, convertible car seats, and booster seats may have different expiration periods.

Can You Use an Expired Car Seat?

It is not recommended. Once a car seat has passed its car seat expiration date, parents should stop using it and replace it with a car seat that is still within its recommended service life and appropriate for the child’s height, weight, and age.

A car seat that still looks new does not necessarily mean it is still within the manufacturer-approved period of use.

In particular, parents should not continue using an expired car seat simply because:

  • The shell is not cracked
  • The harness still works
  • The seat was rarely used
  • The seat was stored indoors
  • It is only needed for a few more months

When it comes to child passenger safety equipment, the manufacturer’s instructions should always take priority.

What Should You Do With an Expired Car Seat?

When a car seat expires, avoid simply placing the intact seat outside where someone else could pick it up and reuse it.

Parents can:

  • Check for local car seat trade-in or recycling programs
  • Remove the harness and detachable components
  • Clearly mark the seat “EXPIRED” or “DO NOT USE”
  • Dispose of the seat according to local recycling or waste guidelines

The goal is to reduce the chance that an expired car seat will be reused for another child.
