Frequently asked questions
What certifications should a crib foam mattress have?
Look for CertiPUR-US (verified foam content, low VOCs) and GREENGUARD Gold (low chemical emissions). OEKO-TEX Standard 100 also indicates no harmful substances. These ensure the mattress is safe for your baby.
Are foam crib mattresses safe for newborns?
Yes, if they are firm and fit snugly in the crib. The American Academy of Pediatrics recommends a firm, flat surface to reduce SIDS risk. All our picks meet this standard.
How firm should a crib mattress be?
It should be firm enough that it doesn't conform to your baby's head or body. A simple test: press in the center; the mattress should spring back immediately.
Can I use a used foam crib mattress?
It's not recommended. Used mattresses may have sagging, stains, or wear that compromise safety. If you do, check for firmness, certifications, and condition.
How often should I replace a foam crib mattress?
Typically every 3-5 years or if you notice sagging, stains, or damage. For hygiene and safety, a new mattress for each child is ideal.
