  "title": "Crib mattresses that stay cool for baby's sleep",
  "question": "Which crib mattress stays cool so a baby can sleep comfortably?",
  "answer": "Naturepedic Verse Organic Mattress: Breathable organic wool and cotton are used to wick moisture and avoid the need for memory foam or gel. Scored cooling and motion isolation very good, pressure relief and edge support good, and durability very good.\nNaturepedic Breathable Organic 2-Stage Baby Crib Mattress: The tester found the breathable cover airy and thick, with a soft, plush three-dimensional organic cotton surface they could press their face into and still breathe freely. It contains no polyurethane foam at all, a structurally different build rather than a lower-emission version of the same foam.\nNaturepedic MC47C (innerspring): Long-term testers rate this mattress highly for durability and for its waterproof layer, and found babies sleep well on it.\nLullaby Earth Gentle Start: This buyer-facing comparison names the Gentle Start its best gentle-start pick and warns that only the cover is breathable: the core underneath is conventional, so air does not pass through the whole mattress the way it does in a Wovenaire-core design.",
