Are used carseats safe to use?
If you are unable to verify that the carseat has never been involved in a crash, do not use it. Above that, you should inspect it carefully to make sure all the parts and labels are intact, and that there are no visible stress marks. You should also verify that the stickers with the manufacturer, model number and date of manufacture are legible. You must also have the owner’s manual, or get a copy from the manufacturer. Finally, you need to make sure the used carseat has not been recalled (or if it has, that the appropriate corrections were made). Older seats may not meet current safety standards. Older seats may also be less convenient and more difficult to use, and may lack the latest safety features. If there is any doubt on the condition or history of a used carseat, please destroy it completely and permanently (using a saw or otherwise) and purchase a new one.
