  "answer": "Lullaby Earth Breathe Safe Breathable Mini Crib Mattress: The maker gives dimensions of 23.5 by 37.5 by 3 inches, agreeing with Strolleria; the other store listing and Healthline give approximately 24 by 38 by 6 inches, so the sources disagree. One store listing says the mattress measures about 24 by 38 by 6 inches, which conflicts with the 3-inch thickness given by the maker and the other store.\nMoonlight Slumber Starlight Dream Crib Mattress (Compressed & Rolled): The mattress is 5 inches deep.\nMoonlight Slumber Starlight Dream Crib Mattress: The mattress is 5 inches deep and wrapped in a woven fire barrier with no spray-on flame-retardant chemicals.",
