Finding the best nontoxic, organic crib mattress for your baby seems to get more challenging, especially as we learn more about how harmful traditional mattresses can be.
There’s much to learn about organic versus non-organic, and latex fibers versus rubber or cotton. And don’t get us started about finding which companies are GOTS certified through the entire process.
As much time as we take picking out the perfect crib and adorable sheets, a safe, organic crib mattress is often an afterthought determined by cost rather than quality.

That being said, there is some unnerving data around the effects of chemicals made in traditional baby mattress production.
“Our research shows mattresses can be a significant source of chemical contaminants in the nursery and bedroom,” says Dr. Brandon E. Boor, an assistant professor of civil engineering at Purdue (source).
Crib mattresses are generally composed of polyurethane foam, a petroleum-derived synthetic material. And they often contain adhesives and other chemical additives. The foam core is usually enveloped with a waterproof cover. These mattress components can release harmful VOCs, some of which can cause respiratory and nervous system damage (source).
First, here’s what to look for when buying a crib mattress plus our recommendations. Or if you’re looking to start off with baby in your room, take a look at our guide to safe, nontoxic bassinets.
Further down, you’ll find more information on which materials and additives you should avoid and why.
WHAT TO LOOK FOR IN AN ORGANIC CRIB MATTRESS
Choosing the best nontoxic mattress for your baby is imperative. With the right information, you can make an informed choice. Keep these requirements in mind:
- Choose a mattress that is entirely GOTS or GOLS certified. This ensures the finished product was made in a certified facility with rigorous standards. For example, “natural latex” is not the same as GOLS-certified latex because the former can contain up to 30% synthetic materials, including polyurethane foam which is toxic and highly flammable.
- Make sure it hasn’t been sprayed with chemical flame retardants (learn more below).
- Choose a mattress without petroleum-based foam. Also beware of brands claiming to use a soy-based foam. You should ask whether it’s 100% soy (many mix a small percentage of soy-based foam in with the highly flammable polyurethane foam), and whether there are chemicals mixed into the foam itself.
- Avoid vinyl waterproofing. Polyvinyl Chloride (PVC) is the most toxic plastic for our health and the environment. (source) Choose an organic waterproof pad from our recommendations below.
- Look for a mattress that is made in the USA. Many crib mattresses are made in China, where oversight, quality control, and contamination are often issues.
- Avoid synthetic or recycled materials. A truly organic crib mattress won’t contain polyester or recycled content.

WHY VOC EXPOSURE IS ESPECIALLY TROUBLING FOR BABIES
“A baby’s exposure to chemical contaminants in their crib mattresses can be amplified since they sleep for 12 to 14 hours every day and inhale air just inches above the mattress surface, where the concentrations of the VOCs (volatile organic compounds) can be about twice as high as standing just a few feet away,” he said. “Their body heat also increases VOC emissions.”
As it stands, federal law does not require mattress companies to list the chemicals they use in their production processes.
An alarming number of toxic chemicals such as boric acid, antimony, modacrylic, formaldehyde, and polyurethane foam are used in the production of baby mattresses. Some of these chemicals are used in the construction of the mattress, glues, or as flame retardants.
When these off-gas, some of these chemicals may be linked to increases in many ailments, including allergies, eczema, organ toxicity, liver issues, and even cancer.
MATTRESS OFF-GASSING AND SIDS
When discussing baby sleep safety, SIDS (Sudden Infant Death Syndrome) and risk of suffocation is a top concern for new parents.
KidsHealth.org says SIDS is the leading cause of death for children between the age of 1 month and 1 year of age. It claims the lives of about 2,500 children each year in the United States. There is no definitive cause for this terrifyingly unpredictable condition, although there are many possible risk factors leading to SIDS.
While the correlation between SIDS and mattress off-gassing is still being investigated, there is reason to consider a connection. When the SIDS epidemic had its first major awareness campaign in 1994, a “Back to Sleep” initiative was suggested (and is still promoted) to parents and caregivers.
This is the first time that back sleeping, running a fan, and keeping baby from overheating were advised. These solutions could explain a connection to off-gassing.
These tactics would put baby’s face away from the surface of the mattress. It also circulates the chemicals up in lower concentrations and throughout the room rather than directly in baby’s direct breathing space. And baby’s sweat and body heat wouldn’t activate a higher concentration of the gasses.
5 COMMON OFF-GASSING CRIB MATTRESS MATERIALS
Certain off-gassing fumes are way more harmful than others. The following are some of the worst off-gassing offenders in crib mattresses and their potential health risks to your little one. Just a reminder, by choosing an organic crib mattress like the ones listed above, you’ll avoid these chemicals.
1. Polyfluoroalkyl Substances (PFAS)
PFAS are a common chemical additive for waterproofing crib mattresses. PFAS are linked to a growing number of serious health concerns like kidney cancer, lowered birth weights, and immune and endocrine system disruption. The latest tests show that 99% of the population has measurable amounts of PFAS in their bloodstream. (source)
A vinyl crib mattress surface is a potent source of off-gassing as the phthalates (a known animal carcinogen) do not stick well to vinyl and therefore circulate in the air. Vinyl and phthalate exposure has been linked to:
- Nervous system dysregulation
- Behavioral issues
- Child IQ deficits
- Decrease in memory
When inhaled, formaldehyde can also cause irritation and damage to the nose, throat and lungs and can increase the risk of developing asthma. This toxin can also still be found in many crib mattresses as an adhesive.
4. Flame Retardant Chemicals
Fire retardants are added to baby crib mattresses with the intention of preventing or slowing the spread of fires. Although perhaps well-intentioned, these harmful substances have been linked to:
- Neurological impairments
- Immune and endocrine system disruption
- Chronic health issues
5. Polyurethane Foam/Memory Foam
Most mainstream foam mattresses are actually made of mostly petroleum based materials – which are highly flammable (think gasoline) and sprayed with toxic flame retardants. To reiterate why a mattress made of gasoline is bad, watch the video in this post.
What’s more, polyurethane foam is highly flammable, meaning that it requires all those toxic flame retardants we just discussed. It is also a porous material that compresses to trap heat and can make babies or toddlers feel hot and sweaty. Without proper waterproofing, this porous material can harbor mold and contribute to respiratory issues.
Picking the best nontoxic mattress can be a daunting task. But we’re lucky to have companies today that use natural materials and are dedicated to baby sleep safety.

Naturepedic exceeds all baby sleep safety standards. This brand avoids the use of latex in their organic crib mattresses for a more allergen-friendly design made specifically for babies and children. Their waterproof mattresses, pads, and accessories feature a patented waterproof surface. And they are all made without harmful chemicals. Naturepedic also meets or exceeds all GOTS, GOLS, Non-GMO, Greenguard and Green America certifications.
BABY SLEEP SAFETY + FLAME RETARDANTS
If you’re like us, once you learned about flame retardants, you probably believed that the tradeoff for inhaling chemicals all night was that if a fire broke out in your home, your mattress wouldn’t catch and your family would have more time to get out safely.
It turns out – that belief is mostly wrong.
Any brand you choose should pass all federal and state flammability standards without the use of any fire retardant chemicals or flame retardant barriers.
Mattress companies are not required to disclose all of the chemicals they use in their products. Many companies soak mattresses in flame-retardant chemicals like polybrominated diphenyl ether, better known as PBDE.
These chemicals are highly toxic, and you don’t have the right to know if they’re included. These chemicals can accumulate in the body through skin and inhalation exposure and are known endocrine disruptors. Exposure can be associated with brain, hormonal, and reproductive damage.
Cotton or wool have been used successfully to inhibit flames and pass the government’s flammability requirements. Silica is another mostly natural, non-toxic fire blocker. Boric acid will be in some crib mattresses as a flame retardant, but is debatable when it comes to baby sleep safety.
Naturepedic is one of the rare companies who use zero flame retardant chemicals (even the more “natural” ones) and still meet all state and federal standards for fire safety.
In addition to using certified organic components, your best organic crib mattress choice is one where the entire crib mattress is also certified organic to the Global Organic Textile Standard (GOTS). Another way to tell that it is safe and high quality is to look for the Greenguard Gold certification. Mattresses that are safe for your body are also eco-friendly.
HOW HIGH SHOULD THE CRIB MATTRESS BE FOR A NEWBORN?
Always follow the crib manufacturer’s assembly instructions and look at your baby’s growth for signs that it’s time to adjust the crib mattress height.
Most baby cribs offer three settings for changing mattress height as they reach size and developmental milestones. Here’s a great illustration from Babylicious to illustrate how high the crib mattress should be for a newborn and through most of the first year.
Newborn – Set the mattress at its highest level for newborns through about 3-4 months. Baby shouldn’t be rolling or pushing up at this setting.
Baby gets mobile or begins sitting – Once baby can sit up by themselves, it’s time to lower the mattress to the next setting. This may be anywhere from ages 4 to 8 months. If you’re baby isn’t quite sitting up yet, but is very mobile, it’s a good idea to lower the mattress.
Baby starts to pull up – When baby shows signs of being able to pull up on furniture, the crib, or your hands, it’s time to lower the mattress to the third setting down. Baby pulling up to a standing position puts them in danger of toppling out of the crib when the mattress is too high.
Baby is climbing or is 35″ tall – Plenty of kids figure out how to climb out of the crib before age 1. Climbing or a height of 35″ or taller means it’s time for a toddler bed or floor bed.
If you plan on co-sleeping, be sure to follow safe co-sleeping guidelines and make sure your bed is also safe from harmful off-gassing chemicals. For big kid and adult size beds, we recommend the high-quality, nontoxic mattresses from Naturepedic and their budget-conscious counterpart, Happsy.
When you choose one of these non-toxic crib mattresses, you won’t have to worry about chemicals might wafting around your baby’s sleeping space… because there simply won’t be any.

I tried to used the 15% off code for Naturepedic and it said it was an invalid code.
Amity Hook-Sopko says
Hi Misty. I sent you an email earlier today but just in case you didn’t get it – I’m sorry it’s giving you trouble.
I just added a crib mattress to the cart from mobile and added code GreenChild15 and it appears to have applied the discount.
We’ve seen a handful of uses of it this week without issue. Maybe try again from a different browser?
If that doesn’t work please let me know and I’ll get in touch with Naturepedic as soon as I get back to the office.
Again – our apologies for any trouble.
