  "question": "Which kids' mattresses need assembly or a specific setup before first use?",
  "answer": "DaVinci M53115W: Setup is unroll and unwrap; the mattress needs 48-72 hours to reach full size before use.\nHalo Essential Breathable Crib Mattress: The blog reports expansion to the full 4.5-inch height within minutes; Strolleria says full expansion takes 24–48 hours, so the sources disagree. The blog reviewer reports noticing no chemical smell or off-gassing; its claim of immediate setup disagrees with Strolleria's instruction to allow 24–48 hours for full expansion.",
