Frequently asked questions
What firmness should a bassinet mattress have?
Infant mattresses should be firm to reduce the risk of suffocation and SIDS. A firm surface means the mattress does not conform to the baby's head. Always check for firmness labels and safety certifications.
Are foam bassinet mattresses safe?
Yes, when they meet safety standards like CertiPUR-US and federal flammability requirements. Ensure the foam is free of harmful chemicals and that the mattress fits snugly in the bassinet without gaps.
How do I clean a foam bassinet mattress?
Regularly wipe with a mild soap and water solution, and allow to air dry. Use a waterproof cover to protect the foam. Avoid soaking the foam; if the cover is removable, machine wash it according to instructions.
Can I use a crib mattress in a bassinet?
No, crib mattresses are larger and may not fit properly, creating dangerous gaps. Always use a mattress specifically designed for your bassinet model to ensure a snug fit and safety.
How long can a baby use a bassinet mattress?
Most bassinet mattresses are for infants up to about 15-20 pounds or until the baby starts to roll over. Once your baby outgrows the bassinet, transition to a crib for safety.
