Frequently asked questions
What firmness is best for a bassinet mattress?
The safest bassinet mattress is firm, as soft mattresses increase the risk of SIDS and suffocation. A firm mattress ensures your baby's head doesn't sink in, maintaining a clear airway. Always look for mattresses labeled 'firm' and check for compliance with CPSC safety standards.
Can I use a regular crib mattress in a bassinet?
No, bassinets require a fitted mattress that matches their size exactly. Using a larger mattress can create gaps where the baby could become trapped, increasing suffocation risk. Always use the mattress designed for your specific bassinet model.
What certifications should I look for?
Look for GREENGUARD Gold (low chemical emissions), CertiPUR-US (foam safety), and OEKO-TEX Standard 100 (fabric safety). These certify low VOC levels and absence of harmful substances. Organic mattresses may also have GOTS certification, but not required.
How often should I replace a bassinet mattress?
Replace the mattress after each child, or if it shows signs of wear such as sagging, stains, or tears. Most bassinet mattresses last about 2-3 years. Check manufacturer recommendations, as some warranties cover defects for a limited time.
Do I need a waterproof cover on the bassinet mattress?
Yes, a waterproof cover is essential to protect against leaks, drool, and spit-ups, preventing mold and bacteria growth. Many mattresses come with a waterproof outer layer. If not, use a fitted waterproof pad designed for bassinets.
