Breathable crib mattresses are all about added comfort and safety. Simply put, babies tend to cry more when they're uncomfortable. Airflow under the baby allows heat to dissipate more efficiently, helping regulate temperature for less sweaty backs and a reduced risk of overheating. Breathability is also about physical safety. In an independent test designed to measure suffocation risk, Naturepedic achieved the lowest risk category, allowing a simulated baby to breathe directly through the breathable surface indefinitely.
