Frequently asked questions
What certifications should I look for in a safe crib mattress?
Look for Greenguard Gold, CertiPUR-US, and OEKO-TEX certifications. These indicate low volatile organic compounds (VOCs) and absence of harmful chemicals.
Is a firm crib mattress necessary?
Yes, firm mattresses reduce the risk of Sudden Infant Death Syndrome (SIDS). A firm surface ensures the baby's face won't sink in, maintaining an open airway.
How often should I replace a crib mattress?
Typically, a crib mattress can last for one child through the toddler years. Replace it if you notice sagging, tears, or if it doesn't fit snugly in the crib.
Can I use a second-hand crib mattress?
It's not recommended, as older mattresses may not meet current safety standards and could have wear or contamination. It's safer to buy new.
What is the difference between foam and innerspring crib mattresses?
Foam mattresses are lighter and often more affordable, while innerspring mattresses tend to be firmer and more durable. Both can be safe if firm and certified.
