What to know about crib mattresses
Your baby spends more time on their crib mattress than on any other surface — often 12+ hours a day, with their face just inches from the material. That makes the mattress core, cover fabric, and any finishes or treatments some of the most important things to get right.
- Welpr focuses on what the mattress is made of: the type of foam or fill, the cover material, and whether flame retardants, VOCs, or chemical treatments are present.
- Because babies breathe faster and have thinner skin, materials that off-gas or contain synthetic treatments deserve extra attention in this category.
Check your current crib mattress
Look at the label or product listing for your crib mattress to see what it's made of. Focus on the foam or fill material, the cover fabric, and any certifications mentioned.
- Look for third-party certifications like CertiPUR-US® (for foam) or GREENGUARD Gold — these confirm the mattress has been tested for flame retardants, VOCs, and formaldehyde.
- If the label doesn't list materials or certifications, check the brand's website — if you still can't find clear details, that's a sign to prioritize replacing it.
Use your current crib mattress more safely
If you're not ready to replace your crib mattress right away, a few simple steps can help reduce your baby's direct exposure to the surface materials.
- Use a tightly fitted crib sheet made from organic cotton or untreated natural fabric to create a barrier between your baby and the mattress cover.
- Air out a new or stored mattress in a well-ventilated room for several days before putting it in the crib — this helps reduce initial off-gassing.
Choose a cleaner crib mattress
The best crib mattresses use simple, well-sourced materials with minimal chemical treatments. Look for organic cotton or wool covers, and foam that is independently certified to be free from flame retardants, VOCs, and formaldehyde.
- Prioritize mattresses with CertiPUR-US® certified foam and covers made from organic cotton, wool, or other natural fibers — and be cautious of vague claims like "non-toxic" or "eco-friendly" without a named certification to back them up.
