Non-Toxic Mattress Guide

updated 1/2024

Most conventional ( non organic) mattresses are still made with PU foam - this has been the standard fill for most mattresses since the 1960s

Some people will claim that once the chemical reaction of manufacturing PU foam takes place, the polyurethane foam is completely inert and harmless. However, many studies certify that many of these chemicals do migrate/ leach out for years. This is important because, unlike PU foam used in a sofa, when it is in a mattress, the user is exposed to these chemicals - at low levels- for many hours a day, every single day, for a lifetime.

In fact, Children and adults sleep on our mattresses anywhere from  6- 12 hours (or more!) a night. The problem with sleeping on a mattress that could be off gassing even small amounts of harmful toxins is that your head is  really close to your mattress for hours at a time, breathing it all in for many hours every day….  cumulative exposure could be a concern

What leaches out of PU foam based mattresses and how?

Plenty. For his book Sleep Safe in a Toxic World, author Walter Mader sent a few mattress to a lab for testing and One memory foam model was found to emit 61 volatile organic compounds (VOCs)… and its not only the memory foam mattresses that create this problem!

The Consumer Products Safety Commission (CPSC)  conducted a study to assess the potential health risks that might result from consumer exposure to fire retardant chemicals in mattresses.  They found that  the average adult will absorb a daily dose of :

.802 mg of Antimony (the inhalation of Antimony causes lung tumors in animals and is considered a probably human carcinogen)

 .081 mg Boric Acid (Roach Killer- a probabe reproductive and developmental toxicant in humans, Long-term exposure to boric acid is suggested to cause kidney damage. ), and 

.073 mg DBDPO (Deca- considered toxic based on liver and thyroid effects in rodent studies, it is also a possible human carcinogen) from flame proof mattresses, every night. 

Additionally, the study did find that five year old children will absorb .5 mg Antimony every night, this is 63 times more poison than the EPA says is safe. No studies have been conducted  on children under 5

While these amounts are quite small for adults, they do add to our ‘toxic burden’ (that is the amount of chemicals we are exposed to day in and day out over a long period of time). And that is the point: while some of these toxins being emitted by PU based mattresses are very very low levels, they do add up.

Before diving into toxins emitted by PU foam based mattresses, its important to understand how they migrate out

  1. Chemical additives like those used and mentioned below are not bound into the final product ( the foam) which is why we see them leaching as easily and for as long as they do.

  2. Some will leech and migrate to the dust we then touch or breathe.

  3. Others will be emitted into the air we breathe as potentially harmful volatile organic compounds, VOCs, sometimes for years 

  4. Finally, a secondary exposure route is that sometimes they leach into ocean water when these foams are thrown out ( affecting fish we eat) .

What additives? Well, PU foam manufacturers are not required to disclose the specific type of flame retardant nor additives used in their products, plenty of researchers have studied PU foam so we know what chemicals are commonly found in them.

Recently an international group of Researchers selected 50 plastic and rubber items that we use in our everyday lives and looked at the chemicals that leached from them once in the ocean.

Among their findings:

  1. all items start to leach additives from the plastic as soon as they enter the water.

  2. polyurethane foam mattress (#49) was among the ten most toxic extracts.

Some of the most concerning chemicals found in PU are:

  • 4-(2,4,4-Trimethylpentan-2-yl)-N-[4-(2,4,4-trimethylpentan-2-yl)phenyl]aniline (CAS 15721-78-5, used in lubricants and greases). .. when not in ocean waters this would likely migrate to dust and air

  • substituted diphenylamines (SDPAs) additives used in many products such as plastics, rubbers, fuels, lubricants, hydraulic fluids and industrial adhesives to prevent materials from undergoing oxidative degradation . These compounds are suspected endocrine disruptors and some have been demonstrated to affect reproduction in mammals [35].

  • 4-methylbenzene-1,3-diamine (more commonly known as 2,4-diaminotoluene, CAS 95-80-7) This compound is commonly used in production of polyurethane foams, and is a known carcinogen

  • The antioxidant methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate (CAS 6386-38-5, RI 1903, match% 85) This compound is classified by ECHA as toxic to aquatic life with long lasting effects.

Other studies have also found:

  • According the EWG , some mattresses have added fragrance to mask unpleasant odors.. these can cause allergic reactions and sometimes contain hormone-disrupting phthalates. 

  • Flame retardants like antimony, Fiberglass, TBPP flame retardant , Diisocyanates10 are also used to make polyurethane foam more flame-resistant. Diisocyanates are highly reactive compounds that can cause health issues like respiratory problems, skin damage, eye damage,  nausea, vomiting, or abdominal pain, as well as increase the likelihood of cancer. Exposure to fiberglass could cause rashes, respiratory irritation and even property damage. 

  • Solvent-based glue often binds the layers of a mattress.  Some mattresses can contain up to 10 lbs of adhesives! These release VOCs and formaldehyde, a known carcinogen.  The most common adhesives used are:

        • Methylene Chloride based adhesives:   also found in paint strippers, high levels of Methylene chloride has been linked to cancer, cognitive impairment, and asphyxiation.

        • n-Propyl bromide-based adhesives: Classified as a VOC, it is is a reproductive toxin.

        • Acetone-based adhesives:  while acetone is not considered a VOC, Some formulations based on acetone also contain other chemicals like hexane, heptane, and mineral spirits. These other chemicals may be classified as VOCs and some may be relatively toxic.

Better options? An organic mattress is definitely a better surface, from a toxicity perspective, to sleep on than a conventional mattress

But, the truth is that buying a ‘non-toxic’ mattress is one of the biggest investments you might make in your non-toxic living journey and it can also be one of the trickiest industries to navigate.

It can be confusing to figure out which mattress to buy, it can be confusing to figure out which claims and companies to trust.  The mattress industry is unregulated and I have found it to be very sneaky:  it is hard to find out what is inside mattresses and there are a lot of companies using terms like ‘organic’ and ‘natural’ very very loosely.   Close to 40% of mattress companies refuse to fully disclose all materials used in their mattresses, failing mostly to provide information on how they make their mattresses flame resistant, waterproof or antimicrobial.   As a general rule of thumb if a company is NOT disclosing everything, don’t buy their mattress.

In an ironic twist you might, literally, loose sleep over the issue.   

Note on affordability: Organic mattress can cost more that non organic mattresses. Babies and young children are more vulnerable to toxins than adults  ( Babies and children detoxifying system isnt as developed as an adults, Babies and children are physically smaller than adults, which results in greater exposures per kilogram of body weight to any contaminants in the air, water, or food compared with adults., Babies and children are more vulnerable to toxin exposure because they progressing through the complex, delicate, and easily disrupted stages of early development) so- if you have to choose/ prioritize, I would always choose getting an organic mattresses for your baby and child and then for yourself.

HOW TO CHOOSE A ‘NON- TOXIC’ MATTRESS

  1. Materials and certifications: you want to search for a mattress made with any of these certified materials or a combination of them:

  • GOTS organic cotton: the Global Organic Textile Standards is the strictest organic certification available. Products with this certification must contain at least 95% certifies organic fibers and the remainder are highly restricted (no flame retardants nor PFAS chemicals are allowed)

  • GOLS latex: The Global Organic Latex Standard. Products that have this certification must contain at least 95% certified organic latex. (the remaining 5% of ingredients are highly restricted- no flame retardants nor PFAS chemicals are allowed, however synthetic chemicals are required to make tree sap into latex foam).   There are two types of natural latex:  Dunlop and Talalay.  While they both come from the same sap from the same type of tree, the manufacturing process is slightly different.  Additional processing used in Talalay latex  can never be certified as organic.  These latex bed can be Oeko Tex certified.  Please note:  natural latex still requires synthetic chemicals to produce

  • WOOL

  • Made Safe certification in another certification that has very strict standards and can be trusted.  They certify both GOTS certified mattresses and natural latex ones)

Certifications and materials I do not recommend:

Certipur :  this is a PU industry owned and regulated certification.  Many of the chemicals it lists as banned are already not allowed in US foam products.

Soy foam / bio foam:  Although it sounds like it could be ‘healthier’ soy foam is not much better than regular PU foam.  Soy foam might contain up tp  20% soy content but can contain as little as 3-5% depending on the product. The rest is PU.  A  common trend is a mattress that  contains, for example, a thin layer of organic cotton over PU foam or uses soybean oil as part of the polyurethane foam, and the mattress in marketed as ‘green’ or ‘natural’.   If it still contains PU foam it will still give off VOCs.   Soy foam also requires petroleum, so it too will off gas VOCs and the expansion of soy plantations in Brazil is partly responsible for de-forestation of the rainforest. Skip these.
