Fire “Safety” in Mattresses
Mattresses are required by the Consumer Product Safety Commission to meet flammability laws. This previously meant that they were almost always treated with bromated or chlorinated flame-retardant chemicals, typically one of the first three on this list:
- Polybrominated diphenyl ethers. PBDEs are associated with hormone-disruption and neurodevelopmental delays, including lowered IQ. The European Union has banned the use of PBDEs in electronic devices. Studies show that children in the United States have higher levels of PBDEs than adults do. Oh, and here’s the kicker: they don’t even work very well at stopping fires!
- Firemaster 550. This nasty chemical cocktail is made with bis (2-ethylhexyl) tetrabromophthalate (TBPH). Yes, you saw that word in there: phthalate. TBPH is nearly identical to DEHP, the phthalate banned in children’s products (including mattresses!!) due to evidence of carcinogenicity and developmental toxicity.
- Chlorinated tris. This is the notorious chemical that was removed from children’s pajamas in the 1970s because it was shown to cause cancer.
- Halogen-free flame retardants. This newer class of chemicals (such as ammonium polyphosphate, aluminium diethyl phosphinate, and melamine polyphosphate) is believed to be much less likely to bioaccumulate than bromated flame retardants. I still prefer my mattresses to be free of even these.
In addition to these notoriously toxic flame retardants, companies may use some of the following ingredients to pass flammability tests: boric acid, silica, melamine, vinylidene chloride, and fiberglass.
The Importance of Fiberglass-Free Mattresses
Fiberglass isn’t a chemical flame retardant, but it can still come with some serious health risks.
Here’s just two reasons that buying mattresses without fiberglass is important:
- No more itchy nights. Fiberglass particles can easily escape from mattress covers. This can cause itching, redness, and respiratory issues like coughing and wheezing. This is especially concerning for children and those with sensitive skin or allergies.
- Better indoor air quality. Fiberglass dust can also float around, potentially triggering coughs, wheezing, and generally messing with your respiratory system.
A Myth About Off-Gassing
Many of my clients think that their mattresses are okay if they are old because they have “already off-gassed.” Unfortunately, this is not true in the case of foam mattresses. In fact, as the foam degrades, more PBDEs (hormone-disrupting flame retardants) may be released.
Are Mattress Coils Dangerous?
There has been a lot of online chatter in recent years regarding metal coils in mattresses. We paid close attention to this and did some research, and we arrived at the conclusion that steel springs present no established danger.
We simply cannot find any credible evidence showing that metal coils can act like an antenna and concentrate EMFs into our sleeping bodies. Phew–one less thing to worry about!
What Is the Least Toxic Mattress Material?
A toxin-free mattress will likely contain some combination of the following materials:
- Organic wool (untreated) is naturally flame- and mildew/dust mite-resistant.
- 100% natural latex (made from rubber trees) is safer than latex blends. The latter may contain petroleum-based polyurethane. It’s important to note that no latex foam mattress can be 100% natural or organic. Turning latex rubber to foam necessitates the use of chemicals, period. Certified latex mattresses simply have less chemical content.
- Organic cotton (grown in untreated soil, without pesticides) can be used for batting or mattress wrapping. There is a robust debate about whether or not the herbicides and pesticides used on cotton crops will wash/bleach out as the cotton is processed. Most studies show that it does, but some folks believe that a residue remains. We believe that the risk of sleeping on a mattress or sheets made from conventionally grown cotton is tiny. Still, for the good of the planet, we should all choose organically-grown cotton whenever possible.
- Trusted certifications from third-party certifying bodies mean that some ingredients in the mattress have been vetted by organizations committed to improving air quality. This also means a safer sleeping surface for you. However, all certifications are not created equally, as you’ll learn below.
Dunlop Versus Talalay Latex in the Best Non-Toxic Mattress Brands
You’ll probably read a lot about Talalay versus Dunlop latex in your search for the best organic mattress. In terms of comfort, Dunlop is firmer and Talalay is lighter and softer. If you’re looking for a GOLS-certified mattress (more on this below), you’ll need to choose a mattress made of Dunlop latex.
Don’t Be Fooled By…
The mattress industry is full of greenwashing. Here are just a few claims that should alert you that a brand may be Sneaky Stuff.
- “Natural latex.” Petroleum comes from the earth, so petroleum-based mattresses can be “natural.” A “natural latex mattress” may only contain only 50% natural latex and may be blended with polyurethane foam and treated with various VOCs. Look for mattresses that specify that they are made from only 100% natural latex.
- “All-natural wool,” “pure wool” or “eco-wool.” Unless wool is certified organic, it is likely processed conventionally with a variety of chemicals. You may or may not be okay with this (I feel that the flame retardants are more concerning). In some cases, a wool producer may not bother with organic certification, despite organic practices.
- Biofoam. Soy- or plant-foam is still made of mostly polyurethane. Biofoam mattresses typically contain less than 20% plant material.
- Certifications. Oftentimes, these certifications apply only to certain parts of the mattress, not necessarily the mattress as a whole. In some cases, the mattress company creates its own certification. You will read more about these certifications in a moment.
Bottom line: There is a lot of deceptive marketing in the mattress world. It is not illegal to throw around terms like “natural,” “green,” and even “organic” without actually having to prove anything.
What to Know About Mattress Certifications
Sorting through mattress certifications is maddening. Here’s just some of why that is:
- First of all, not all certifications are created equal. Some offer great assurance that your new mattress will be non-toxic, while others are essentially meaningless.
- What’s more, just because a company shows a certification doesn’t mean all of the material in that mattress is certified. One of our readers wrote to us about a mattress that contained Oeko-Tex 100 certified wool, but the company wouldn’t confirm that they solely purchase the wool from this source. Thus, in this case, it would be impossible to know if the mattress you’re purchasing contains the certified wool or not, to say nothing of the other materials in this mattress.
- Sometimes, a mattress will claim to have a certification that they don’t really have. One of the most common deceptive practices is when a manufacturer claims to have GOLS certification for their latex mattress, and even display the GOLS logo on their website. They might even show an actual copy of it on their website, complete with date and signatures. If, however, the certificate is not written to the same name as the manufacturer, it is not particularly meaningful. They are commonly written to a latex supplier out of Sri Lanka, India or South America. Such a certification shows only that the latex was certified up to that point on its journey to becoming someone’s bed. Between Sri Lanka and your bedroom, all sorts of things can happen to the latex to cause it to be more toxic than the certification implies.
So, how do you know if a mattress is non-toxic?
Best Non-Toxic Mattress Certifications
The two certifications to look for in your mattress are GOLS (Global Organic Latex Standard) and GOTS (Global Organic Textile Standard).
(And again, the best non-toxic mattress brands have these certifications written directly to the mattress manufacturer.)
To obtain a GOTS certification, at least 95% of the mattress must be made of certified-organic materials. Certain chemistries are prohibited entirely, even for that other 5%. A GOTS certification on a mattress means that the entire manufacturing and distribution process is environmentally safe and socially responsible.
Prohibited materials and contaminants in a GOTS-certified mattress include:
- Polyurethane foam
- Heavy metals
- Formaldehyde
- The fire retardants listed above
One thing we love about GOTS certification is that in order to obtain it, a mattress must be produced in a facility that is also certified. In fact, GOTS certifiers visit production facilities as part of the certification process. (If you are curious about a brand that we don’t review in this guide, you can check for GOTS certification in the GOTS database.)
Similar to GOTS, a GOLS certification means that the mattress is made of at least 95% organic latex. This means that 5% of the latex can be made of synthetic materials, although these are still restricted in some important ways). A GOLS certification requires third-party testing and inspections by certifiers.
Good Non-Toxic Mattress Certifications
While OEKO-TEX Standard 100 doesn’t require any organic materials to be used in a mattress, it does set limits for VOC emissions (such as formaldehyde). It also prohibits the use of dangerous flame-retardants and dyes. When looking at mattresses, the highest level of OEKO-TEX certification is Class 1.
Greenguard-certified mattresses have been tested for, and are within limits of, several hundred VOCs, including formaldehyde. Greenguard Gold has stricter standards than plain old Greenguard, but they are not testing for flame retardants or PFAS.
Okay Non-Toxic Mattress Certifications
Organic Content Standard 100 just means that some of the ingredients are organic. This certification doesn’t ban flame-retardants or other harmful chemicals.
CertiPUR was developed “by members of the global foam industry,” although it does ban the use of some chemicals, such as PBDE flame-retardants and formaldehyde. It’s important to know that CertiPUR does not certify an entire mattress, only the foam portion.
A Sneaky Mattress Certification
NAOMI (National Association of Organic Mattress Industry) was created by Pure Rest Organics, which is a mattress company. Obviously this means that a NAOMI certification no way independent or third-party
The Bottom Line on Non-Toxic Mattress Certifications
When it comes to mattress certifications, most are of SOME value, but they can be used sneakily by mattress manufacturers.
You really need to ask to see the actual signed certification, keeping in mind that if it’s out of date, it’s worthless. You also want to make sure that the entire factory that produces your mattress is certified to be free of toxins, particularly flame retardants. This will guarantee that you don’t have to worry about cross-contamination and mattress health issues.
If You Can’t Afford the Best Non-Toxic Mattress
Maybe you’ve looked all the way down to our Okay Stuff category and checked out the coupons (top of this page), and you simply don’t have it in your budget to upgrade to a safe mattress right now.
Readers often ask: “How do I protect myself from a toxic mattress?”
Unfortunately, there’s no way to wrap a mattress to protect yourself from VOCs. However, running a robust air filter will go a long way towards purifying your indoor air. I have the Austin HealthMate PLUS Air Purification System in my bedroom because while I do have a toxin-free mattress, I also have other furniture and rugs that aren’t as clean. I love knowing that the air filter is mitigating the damage!
You also might consider a futon as an alternative to an expensive, non-toxic mattress. They are much more comfortable than they were in your childhood, and I love the ones by Soaring Heart in particular. (Conventional or Sneaky futons will be loaded with all the same scary chemicals as mattresses.)
Here’s where I explain the difference between a mattress and a futon:

Hi there-
We would consider that bed Bad Stuff, unfortunately. Soaring Heart does offer a nice zoned support bed that is incredibly comfortable. Please feel free to email john@gimmethegoodstuff.com for more help choosing the right mattress!

Hi! I was wondering if you had heard of Avocado Green Mattresses? They are a new company and I just ordered one for our new bed and I’m wondering what you think. They claim to be a company in response to all of the false “organic” and affordable mattress certifications out there and are made with “natural latex rubber, wool and GOTS organic cotton”. Any info you have would be helpful! Thank you!
I found them here: https://www.avocadogreenmattress.com/maurice dudeley
When shopping for a mattress, look for one that’s free from latex, soy based foam, and chemical retardants, and look for one that uses materials like wool, cotton, and all natural rubber instead.

Hi Ryan,
ThanksJohn here…Unfortunately Sleep Number is a long way from being “Good Stuff”. They are way at the other end of the spectrum. “Nontoxic” is simply not their thing. Feel free to contact me directly at john@gimmethegoodstuff.com and I’ll be happy to help you find a truly nontoxic mattress.
Ryan
Have you done any research on SleepNumber beds? Our family of 4 wants to upgrade to a king mattress and I don’t see sleepjumber anywhere on this page. Sleepnumber uses air pressure/air chambers to adjust the firmness. Specifically thinking about the C3, C4 or P5 mattress. Thank you so much!

Hello – I am interested in purchasing the intelliBed or the Purple mattress and wanted to know if they are, “non-toxic” beds like they claim. I really appreciate your time.
Kind Regards, GlennKasey E
Thank you so much for your reviews, whenever I’m curious about a product I look on your site.
I am curious if you know anything about the newton rest crib mattress? It seems to be a good product, but I can never be to sure! Thanks for your time!

Hi!
Thank you for such a helpful and informative site/discussion!
I am vegan so I want to avoid wool but I still want a non-toxic mattress.
I have narrowed my search down to three options.
I know your thought about Soaring Heart but can you please give me your opinion about the other two options?
Thank you!
1. Soaring Heart- latex (no wool with Dr. prescription)
2. Seattle Natural mattress
3. Ergovea – Madera Latex Mattress

Warm wishes, MireyaAbsolutely love your site! Any updates on the Nook Pure?
Silvana
Great information! Thank you so much!
My daughter and son- in- law after much research, purchased a customized Obasan, made in Canada (local for us). Very expensive, but health issues were a priority. There was a reference to this company earlier but I didn’t see a response. We are in the market for a new mattress and I would be interested to know what your thoughts are.
Thank you
cathy
I’m looking forward to your updated mattress guide! Can you review sleep on latex? It got high remarks in consumer reports and the website says it’s natural latex/organic cotton. Families that can’t afford thousands for new beds need some options too. Thank you for your awesome guides!
Karen
I notice that you have rarely mentioned OMI Organicpedic and Organicpedic Earth mattresses. Someone else asked you about this brand in an earlier comment but there was no reply. They seem to have all the correct certifications and I like the feel of them more than the Savvy Rest. I am worried that I may be overlooking something. Do you have any thoughts on this manufacturer or either line of their products? Thank you so much for all the helpful information!
Dina
What did you end up going with? I am looking at that brand now too.
Bérénice L.
Hi, Nice article, very helpful to navigate what is important and how to look for it!
Did you look into Sleep on Latex? They look legit (GOTS organic cotton, Oeko-Tex and ECO natural latex, GreenGuard Gold mattress), and they are the cheapest I could find for 100% natural latex mattress … I am curious to know what you think! What about Sleeping Organic? Thanks!John Goss
Hi Rachel,
Thanks,My Green Mattress does not qualify as “Good Stuff”. There is a lot of deceptive marketing in the industry and it’s worth taking a closer look. Feel free to contact me directly… john@gimmethegoodstuff.com I’ll be happy to help you figure things out.
Rachel
This is so helpful! Thank you.
Have you looked into My Green Mattress at all? They seem like a good, affordable option.Mallory
I’m wondering about this company too. It seems like a really good option. I’m having a hard time finding a downside
Mom
Update on our 2 month ordeal with Vivetique/The Natural Bedroom: after a month of sleeping on the wrong mattress Natural Bedroom/Vivetique had delivered us, they finally exchanged the mattress, but for something even cheaper! At that point, they owed us a few hundred dollars in refunds—though Steve Carwile (the owner) kept promising a refund in the difference but would not process the transaction. The 2nd mattress he delivered to us was so cheap that my husband refused to sleep on it. By this time, 1.5 months had gone by since we bought our mattress from Vivetique, and they still had not refunded the difference between the mattress we had bought and the less expensive mattress they had delivered. We had enough of their lies and returned everything and were promised a full refund after the items had been picked up (defective box-springs, mattress and toppers). Vivetique’s delivery guy picked up everything, but we were never issued a refund. After days of waiting for a refund confirmation from Steve Carwile, we finally disputed the transaction with our credit card company. However, a month later, Steve Carwile told the credit card company that he had never received the returned merchandise back at this store, therefore being unable to issue a refund. I contacted his delivery guy, who confirmed all items had in fact been returned to the store and he had signed documentation to prove it. Thank goodness, we won the dispute and received a full refund of approximately $3,000, never having to deal with such crooks ever again!
FYI: Several months later and my lower back is still in pain from having slept on Vivetiques defective and cheap mattresses—I’m getting chiropractic adjustments to deal with the pain.
Janice
hi.
I’m wondering if you can provide some feedback on some Canadian based mattress companies that sell “good Stuff” everything I seem to find is U.S and cost way over my budget. We had to upgrade to a king and ended up getting a toxic bed and hate it.

We bought a king and twin organic cotton futon mattress from Cotton Cloud and now I am curious about your thoughts, too… Thank you!

Alissa O'Connor Rottingen
Love your site.
Need to purchase a new mattress asap. It’s too bad that living toxin free isn’t a luxury everyone can afford.While I would love a mattress, I may only be able to afford a futon. Is there a futon with latex and cotton, but not wool? I may have a sensitivity to wool. If a wool sweater makes my neck itch, would the wool inside the mattress be an issue?
If I do go with a futon, would you recommend a topper (latex) for more support/cushion?
Fenny
Hi John,
What about Healthy Choice Organic Mattress? http://hcmattress.com/index.aspx They are in the Real Simple magazine. Please let me know since they have a President’s Day Sale and I need to replace my mattress this month. Thanks!joanna
hi I found this site called sleepez.com that claims to you use all natural latex. In addition they say they do not use flame retardants to treat or any pdbes or harmful plastics. Seems way cheaper then your other recommendations. Have you ever heard of this company or think their claims are Legitimate?
thank youJohn Goss
Hi Folks,
The above rep, Bradley Bonic, Director of Marketing for My Green Mattress, would like for you to consider buying their products and is likely concerned that they do not get a “Good Stuff” rating from us. Brad says, “…our latex is 100% natural Dunlop latex”. Brad likely knows as well as I do that the term “natural” has no legal meaning and is tossed around a lot. Marketers like Brad know that the term “natural” is often good enough to lead us to believe that the product is safe, or good for us, or nontoxic. A stroll through any supermarket aisle will prove the flaws with that belief. Many mattress manufacturers use that term, but from our perspective they need to be able to back that up with GOOD independent 3rd party certifications. The term “natural” is essentially meaningless. Poison Ivy is “natural”, as is plutonium. I don’t think we want to sleep on those things. Brad also says their latex “is Oeko-Tex Certified”. I could not find an image of the actual signed/dated document with the name “MY Green Mattress” shown that would back this claim up, so I went to the Oeko-Tex website and conducted a database search to see if My Green Mattress was listed as a certified manufacturer. The results?…“No results for this query.” In other words, it does not appear that My Green Mattress actually holds an Oeko-Tex certification. An Oeko-Tex logo displayed on a website has plenty of marketing value, but oddly, I don’t see it used on the My Green Mattress site. And even if they use the logo, that in itself does not mean that the manufacturer is properly certified. You need to see the actual certificate with the manufacturers name and a valid date on it. Brad also claims that they will soon have GreenGuard Gold certification. That may be true, I don’t know, "but GreenGuard, by measuring only emitting chemicals, is significant for what it does not measure: It does not measure any of the heavy metals (lead, mercury, copper, etc.) It does not measure PVC, which is a polymer and therefore not volatile It does not measure phthalates (except in the Children and Schools certification).†Finally, (and this is the biggest problem) I cannot find what sort of flame retardants are used in their latex mattresses. Without knowing that, everything else seems petty! All of the above is far too common in the world of mattress manufacturers. I see it every day. If there is something I’ve missed I invite Brad to correct me. We are just a few weeks away from publishing our new, updated safe mattress guide. There are some changes. Look for it soon. It’s a confusing world. Buyer beware. Best, JohnJohn here…. I do research for our website (Gimme the Good Stuff) Occasionally a mattress manufacturer will jump into this conversation, as we see in the above post. We welcome their input. We can all learn.
Brad
Hello everyone. I wanted to provide some updates on our products after reading some of your concerns. My Green Mattress uses all natural wool sourced from California that contains no polyester fibers and is not treated with any harsh chemicals. Our cotton is GOTS certified organic and our latex is 100% natural Dunlop latex, which is Oeko-Tex Certified. We also recently obtained our GreenGuard Gold certification and will have that live on our website as soon as possible. If you have any other questions or concerns please do call us directly; we love talking about our products.
Maia James
We have an updated guide in the works that should be ready this month! We appreciate your patience. :)
Deserae
avocado does show a GOTS certification and eco institut
are those what we should be looking for?
Randy
Any update to Lifekind.com if they are in the good or bad listing since their mattresses are listed as organic natural rubber with the Greenguard , GOTS and GOLS certification?
Olya
Hello:)
Thank you so much for all this helpful information. I wanted to ask what you thought about the Naturepedic No Comprimise organic cotton classic lightweight crib mattress? You guys sell the classic 150 organic one… do u think it’s safer/healthier than te lightweight one? Thank you so much! Olya
Mark J
We’re also looking at a White Lotus mattress for our kid. Curious why you went with the Green Cotton instead of an Organic Cotton mattress. The salesperson said they can’t guarantee the farms where they source the green cotton don’t use pesticides. The green cotton is significantly cheaper, so I’m just looking to weigh the pros and cons. Thanks for your in-depth review!
Ashley
Could you guys do an updated guide? Please!
Madeline
Hello
Would love your opinion Thank youThank you so much for all this amazing info! I want my daughter to have the safest mattress! Unfortunately my budget is very tight! I was curious how your felt about the tuft and needle mattresses? I know it’s. It the best because it is foam but wondering if it’s not too bad? I’ve been trying to do some research but it’s confusing! I was going to get the White Lotus Green Cotton & Wool Dreamton Futon but is sooo expensive!but No returns That’s a lot of money to have no idea how it feels!

Hi, thanks so much for your website. Is there any chance that you have ever looked into Room & Board’s mattresses? They claim to be flame retardant free … would love to know what you think of their mattresses.
Thanks so much in advance!John Goss

Spindle does not make our list of “Good Stuff”. Their certifications are dubious.Fenny
What about Spindle Mattress that doesn’t cost $$$$. Anyone purchase Spindle Mattress? Spindlemattress.com
John Goss
John here…
Avacado shows zero certifications on their site. They simply claim that their latex is “Natural”. The term “Natural” has no legal meaning and is commonly used by many manufacturers who are hoping that “Natural” will be enough to convince us that their product is less toxic. There is a lot of deceptive marketing in the industry. It is worth asking questions. Best,John Goss

Hi Kate,
We have taken a look at WaveSupport and although we are generally not fans of plastics, it appears to be a good stuff. It tests well. Thanks for the heads up re: frames. I tend to think of bed frames as being made of wood, but you correctly point out that some are made from metal. BestJohn here…

Hi Cathy,
John here… Brentwood Home appears to have no independent 3rd party testing or certifications. As such they would not be considered “Good Stuff”. There is too much misleading marketing in the mattress industry. Feel free contact me directly at: john@gimmethegoodstuff.com Let me know what sizes you are looking for.Nika
I would also like to know about newton mattresses as well. My sister and brother in law want to gift it to us but I don’t know much about it. Please help. Thank you in advance!!!

Have you researched Brentwood Home beds…looking at the Coronado on sale at Costco. Their website looks good and says they are non toxic. I want to replace my 3 teen children’s beds and mine with healthier beds (our old ones are older Sealy) so I can’t spend a fortune. Thank you!
Kate
Hello Maia,
I was looking to purchase mattresses from your store and I noticed that you don’t carry all wool mattresses. Is there any reasons for that? I was leaning towards all wool mattress and was recommended the futon shop. Any thoughts on that company? Also I need a crib mattress and the Naturepedic light version seems good but i just wanted to make sure that the wavesupport technology doesn’t off gass or emit anything? As far as I understand it’s a new technology so I’m worried if enough testing have been done to prove it safe. Also you forgot to mention that it’s not just coil mattresses that produce EMF but also bed frames. The same article is featured on Dr. Mercola site and he talks about bed frames as well: " …bed frames and box springs are made of metal, and the length of a bed is exactly half the wavelength of FM and TV transmissions. The maximum strength of the field develops 75 centimeters above the mattress,…" Any suggestions on cribs brands without metal frames? I haven’t seen any that wouldn’t have a metal support for the mattress. Best regards and thank you for the great work you do!
