  "title": "Car seat liners and inserts: safety notes",
  "question": "Are aftermarket inserts or liners safe to use with a car seat?",
  "answer": "Britax Seat Saver Waterproof Liner: Forum users treat the Britax liner as approved for Britax seats because Britax says it was crash-tested for them; for other harnessed seats they say it may fit but has not been tested. Britax Head & Body Support Pillow: Forum members were unsure whether the pillow was crash tested and for which seats, and were reassured once Britax's statement that it is approved for use in all Britax infant and convertible seats was quoted. It must not be used as an infant insert, and must not be used for children over 22 lbs. Several posters said it looks much like the aftermarket Snuzzler insert, which some consider unsafe, and debated whether a manufacturer-branded version is any different.",
