Safe to Buy a Used Car Seat, Stroller, or Crib?

While all car seats must pass minimum federal safety standards, some may provide additional margins of crash protection, and some are easier to install than others. That’s crucial, considering a poorly installed car seat leaves a child vulnerable in a crash.

“Those reasons, along with continuous ease-of-use and safety improvements, make a strong case for investing in a new, top-performing car seat,” says Emily A. Thomas, PhD, manager of auto safety at Consumer Reports’ Auto Test Center.

The life span for most car seats is six to 10 years. In many cases, an expiration date is printed on the manufacturing label—make sure you’re abiding by it, because a car seat outside its expiration date won’t provide the protection of a newer model. If the expiration date is not on the manufacturing label, you can find the information in the car seat owner’s manual and do the math based on the date of manufacture.

If you’re buying or inheriting a secondhand car seat, use our interactive decision chart to find out whether the seat is safe to reuse. In addition to the seat’s expiration date—which ensures that the seat hasn’t become too worn—you’ll also want to check whether the car seat has been involved in a crash, which could weaken the seat’s structural integrity beyond what you can see.

Should you end up with a car seat that’s not safe to reuse, don’t haul it to the curb or town dump—it might tempt strangers to use it for their baby. Instead, strip the car seat to its shell, removing fabrics, harnesses, and buckles. Then mark “Do Not Use” on it, and check with your local authorities to find out whether any components can be recycled before you dispose of the car seat.
