We strongly recommend that you replace the seat car, even if it does not appear damaged, because its hull may present invisible cracks.
If your vehicle has an accident, check out the user guide for your seat to see if the manufacturer recommends that you no longer use the car seats.
** Note however that many MANUFACTURERS and INSURANCE COMPANIES say you absolutely must change it, even if it doesn't appear to be damaged.
FOR SEAT REPLACEMENT
Check with your insurance company if this type of property is included in your policy.
If you need to buy another seat in due to an accident, you can include its value in your insurance claim. Also, before using an old or used car seat, make sure that it has never been involved in an accident.
