What Are the Recommended Safety Standards for Mini Crib Mattresses?
The recommended safety standards for mini crib mattresses ensure that they provide a safe sleeping environment for infants and toddlers.

- Material Safety: The materials used in the mattress should be non-toxic and free from harmful chemicals. Look for certifications like CertiPUR-US or GREENGUARD Gold, which indicate the absence of harmful substances such as phthalates, formaldehyde, and heavy metals.
- Waterproof Cover: A waterproof cover is essential for maintaining hygiene and protecting the mattress from spills and accidents. This feature not only helps in easy cleaning but also prevents mold and mildew growth, ensuring a healthier sleeping environment.
- Breathability: A breathable mattress promotes airflow, helping to regulate the baby’s temperature during sleep. This is important for comfort and can also reduce the risk of overheating, which is another factor linked to SIDS.
