The safest way to dispose of an expired car seat is to render it completely unusable and then check with your local trash service or recycling facility for specific guidelines. Most car seats have an expiration date—typically 6 to 10 years from the manufacture date—because materials like plastic and foam degrade over time, compromising safety in a crash. Simply throwing it in the trash intact risks someone else reusing it unsafely.
Your first step should be to dismantle the seat. Use a screwdriver or power drill to remove the fabric cover and harness straps. Then, cut the straps with scissors and use a permanent marker to write "EXPIRED - UNSAFE" on the shell. This visual warning is a crucial step. Finally, break the plastic shell if possible.
Check with your local municipal waste authority for disposal rules. Some areas accept them with regular trash if prepared this way, while others have special bulk item pickup schedules. A growing number of communities offer recycling programs, though these can be limited. Some retailers occasionally host trade-in events, offering a discount on a new seat in exchange for properly recycling an old one.
The table below outlines the primary disposal methods and their key considerations.
