What to check on a second-hand car seat
- Choose a listing in which the seller states the seat's history.
- Look at the production date on the shell; most manufacturers set a lifespan of 6 to 10 years.
- Look up the manufacturer's vehicle list to see whether the seat fits your car.
- Check in the listing whether the harness, cover and ISOFIX base are original, and check on arrival that the straps adjust properly.

Frequently asked questions
Is it safe to buy a second-hand car seat?
Yes, if you know what you are buying. Choose a listing that states the age, the history and the parts included, with the manual or the manufacturer's vehicle list, and check the seat when it arrives.
Does a car seat fit every car?
Not always. Especially with ISOFIX and a support leg, it depends on the rear bench and the floor of your car. Most manufacturers publish a vehicle list of the cars the seat was tested in.
Do I need an ISOFIX base?
Not strictly. Most infant carriers can also be installed with a regular seatbelt. But an ISOFIX base makes installation faster and reduces the chance of fitting it incorrectly. If the listing includes the matching base, that's a real bonus.
