Child Car Seats - Working/Non-Expired/Accident Free
Child car seats are designed to fit inside an automobile's backseat to secure small children. (Expired car seats, or those involved in a car accident are considered "Rigid Plastic" & can be recycled once the seat is stripped of its cover &/or straps/buckles. Give the latter away to owners of similar models for use as back ups or replacements due to spills.)
