Aftermarket Car Seat Products

Kiddo is seating in a carseatAftermarket car seat products are items not sold with a car seat. The products claim extra comfort, style and protection, but do not be fooled! Aftermarket products may void your car seat's warranty. Worse yet, they can prevent your child from being secured correctly or can come loose in a crash and cause serious injury. Some common aftermarket products include, head support cushions, harness strap covers, car seat covers, add-on toys and trays, seat belt adjusters and headrest mirrors. Until these products are tested and there are federal guidelines for them, do not use add-on items with your car seat.

To learn more, consider attending a car seat safety check.
