Crib mattress safety: what to know and look for
Shopping for a crib mattress can be overwhelming and confusing. With all the different types, materials, and safety standards to consider, it can leave you feeling like you need a chemistry degree to make a decision.
But with babies spending up to 18 hours a day sleeping, choosing the right mattress is a crucial investment in their safety and comfort.
Let's break down the different types of mattresses, and explore the safety standards and certifications to look for so you can confidently choose the best option for your little one.
Crib mattress safety basics
There are so many factors to consider when purchasing a mattress for your little one's crib, but let's start with the safety basics.
Size
The mattress should fit snugly inside the crib with no gaps between the mattress and the crib's perimeter. The size of the mattress is an important safety feature, as any gaps within the crib space could cause entrapment or suffocation.
The Consumer Product Safety Commission (CPSC) has standardized the dimensions of full-size cribs and mattresses to improve safety standards and make it easier for parents to purchase without worrying about sizing.
A mattress for a full-size crib should be no more than 6 inches thick, at least 27 ¼ inches wide, and 51 ¼ inches long. By law, non-full-size cribs, such as mini cribs or oval cribs, must be sold with the mattress included.
Firmness
One of the most important factors to consider when choosing a crib mattress for your baby is its firmness. You might be tempted to opt for a soft, cushiony mattress, but this can be dangerous for your little one as it poses a risk of suffocation.
A firm mattress is crucial to help prevent Sudden Infant Death Syndrome (SIDS) and promotes healthy bone development while your baby sleeps.
Buy new
It's best to buy a new crib mattress rather than a used one. Older mattresses might not meet current safety standards and may also contain allergens or bacteria that can harm your baby.
Types of crib mattresses
When shopping for your little one's mattress, you'll find there are two main categories—foam and innerspring.
Foam
Foam mattresses are popular for cribs as they are lightweight and often less expensive than innerspring varieties.
While most foam mattresses are made from high-density polyurethane, some eco-conscious companies have started using soybean or other plant oils instead. Additionally, specialty mattress companies have created organic alternatives from wool, cotton, rubber, and coconut fiber. These organic options can provide your baby with a more natural sleep environment and may be a good choice if you are concerned about chemicals or allergens.
It's worth noting that foam mattresses differ from memory foam, also known as "viscoelastic foam." Memory foam is designed to conform to the shape of whatever is placed on it, which is unsafe for your little one. The American Academy of Pediatrics (AAP) recommends avoiding crib mattresses or mattress toppers made from memory foam.
Innerspring
Innerspring mattresses are designed to be durable and strong, with steel coils that provide support and resilience. Unlike foam mattresses, innerspring mattresses do not compress as easily and tend to last longer.
The construction of an innerspring mattress can vary greatly, with factors such as coil count, coil thickness, insulator pad, cushioning layer, and cover all affecting the quality and price of the mattress.
Crib mattress covers
Between diaper blowouts and spit up, there's no doubt that your little one's mattress will get messy. Leaks and spills can quickly turn a clean and hygienic mattress into a breeding ground for harmful bacteria, mold, and other germs that can pose a risk to your baby's health. This is why many parents choose to purchase a waterproof mattress cover or pad.
While vinyl and PVC covers are popular and effective, many contain high levels of chlorine and phthalates. These chemicals are known to release toxins into the air that have been linked to cancer, reproductive concerns, and other chronic health conditions.
Try to look for mattress covers labeled as vinyl, PVC, and phthalate free to ensure your little one's sleep environment is clean and healthy.
Standards and certifications to look for
The crib mattress you purchase for your baby must meet the federal safety standards set by the CPSC, but there are additional certifications to look for to help you make the best decision for your little one.
Global Organic Textile Standards (GOTS)—This certification is recognized as the world's leading processing standard for textiles made from organic fibers. A minimum of 70% of the material used in a crib mattress must be organic to achieve a GOTS certification.
Oeko-Tex Standard 100 Certification—This globally recognized certification ensures that a product is free from hundreds of harmful chemicals, including pesticides, heavy metals, and formaldehyde.
GREENGUARD Certification—Products that have earned this certification have been tested to meet rigorous standards for low levels of volatile organic compounds (VOCs) and other harmful chemicals that can impair a child's developing immune and respiratory systems.
Promoting healthy sleep
As parents, providing a safe and comfortable sleeping environment for your little one is a top priority. Selecting the right crib mattress can seem like a daunting task, but with the proper knowledge and research, you can create a cozy and safe environment for your baby's sleep.
And remember choosing your little one's mattress is just the first step. There are many things you can do to establish healthy sleep habits for your baby. From consistent bedtime routines to safe sleep practices, setting a strong foundation is key.
