  "title": "Crib mattresses with edge support for keeping a baby centered",
  "question": "Which crib mattresses offer edge support that helps keep a baby centered?",
  "answer": "Lullaby Earth Breathe-Safe 2-Stage: Testers describe the mattress as lightweight but strongly supportive, with firm edges that suit a newborn, and say the light weight makes the claimed 3D air circulation feel genuinely effective. Firmness: Dual firmness gives a firmer side for infants and a less firm reverse side for toddlers. Moonlight Slumber Chill Baby Crib Mattress: It measures 27.5 by 52 by 6 inches.",
