The Winners: Our Picks for the Top Organic Crib Mattresses

Keep reading for our reviews and ratings, plus more information about how to choose from among all the organic crib mattresses on the market, and why it’s such an important decision. If you have a bigger kid, read our best organic kids mattress guide.

When I was pregnant with our daughter, I hated the waiting. Pregnancy wasn’t my bag, and to keep my mind off of what seemed like a never-ending wait, I threw myself into research. Whenever I found a spare moment and a bit of energy (a rare combo, to be sure), I combed the internet for different baby products and added them to our shopping list.

And you know what I realized?

Finding a safe, non toxic crib mattress is one of the hardest things when shopping for a new baby.

When it came to sippy cups and high chairs, I asked friends and was able to make decisions fairly easily.

But when it came to choosing from all the organic crib mattresses on the market , I found myself stuck.


Finding the Best Organic Crib Mattress is Kind of Scary

The Internet is full of warnings of the dangers hidden in within cot mattresses.

Toxic VOCs, fire retardants, and phthalates that will harm your baby and the planet.

Killer mattresses that will suffocate your baby (and also breathable mattresses that apparently won’t).

Hidden mold reservoirs that will result in lifelong asthma and breathing difficulties.

The more I read about this essential item, the worse it got. And the deeper I went into the rabbit hole of research.

Why Get an Organic Crib Mattress?

Babies spend about 12 hours per night sleeping in their cribs. 

Add in a few naps throughout the day, and many babies spend more than half of each 24-hour day in their crib. 

While most moms and dads know this, research backs it up: very young infants sleep and average of 17 hours per day. Older babies and toddlers sleep for 13 to 14 hours within a 24 hour period.

Sleep is a Time for Development, Not Damage

For infants, toddlers, teenagers and seniors, sleep is a universal need. Just as moms and dads need enough sleep, so do babies.

Sleep keeps adults healthy. But for babies, it’s a key part of their development into thriving, healthy children. 

Here’s what just some of the evidence has to say about the importance of sleep for babies:

  • Sleep is a key for very young babies’ ability to learn. Sleep facilitates brain development and maturation, and allows babies to explore the world in increasingly sophisticated ways (source).
  • Sleep plays a key role in babies’ memories. Through sleep, babies can consolidate information they experienced while awake (source). 
  • Babies keep learning while they sleep! Evidence suggests babies process sensory stimuli and learn about their environment…even when they’re snoozing (source). 
  • Better nighttime sleep is correlated with higher cognitive scores in babies (source).
  • Babies who sleep better have been found to be more approachable and adaptable (source). 
  • Sleep helps babies manage and respond to stress (source), such as being briefly separated from their moms or being prevented from playing with a toy. 
  • Good sleep in babies helps prevent obesity and too much weight gain in young children (sourcesource).  

Add to that, sleep plays a key role in our health at a cellular level. Researchers have found that, during sleep, our bodies remove potentially toxic waste products from our brains. And it’s also key to neuroplasticity – our brain’s ability to adapt. 

According to Johns Hopkins Medicine:

Depression, seizures, high blood pressure and migraines worsen. Immunity is compromised, increasing the likelihood of illness and infection. Sleep also plays a role in metabolism: Even one night of missed sleep can create a pre-diabetic state in an otherwise healthy person.

Put simply, sleep is a time for your body – and your baby’s body – to recover from the environmental stressors of the day. It’s a time to detoxify, not deal with even more chemicals, like flame retardant chemicals and materials that aren’t eco friendly. 

And as parents, it’s our job to support a healthy sleep environment, starting with choosing from the best organic crib mattresses for your needs.

That’s why a safe organic cot mattress and non-toxic bassinets and non toxic cribs are really smart additions to your baby’s nursery (and be sure to add organic toddler pillows to that list when the time comes!).

What is the Best Organic Crib Mattress for Babies?

We’ve rounded up what we think are some of the top organic mattresses for babies and toddlers that are on the market today.

Naturepedic’s Breathable Lightweight mattress won us over on value for money combined with safety, with Brentwood Home’s Wildfern Crib Mattress coming in second as the runner up. We think the Wildfern is a great choice for most families, but acknowledge it doesn’t have the same brand recognition that a Naturepedic organic baby crib mattress does. As of November 2020, it’s also currently unavailable – we’re not sure if that’s a permanent thing or temporary.

Keep reading for our reviews and more info.

Naturepedic Breathable Lightweight 2-Stage Crib Mattress

A cross section of the Naturepedic Breathable Lightweight crib mattress

The Winner

There’s a lot to love about the entire line of Naturepedic organic crib mattresses, but the Breathable Lightweight waterproof mattress stands apart as one of the best. Affordably priced as a mid-range mattress at $349.

The Naturepedic organic breathable series is the company’s mid-range line of safe, organic crib mattresses. Standing apart from the cheaper Classic series, this mattress has a breathable, removable cover. The breathable sleep surface is made from organic cotton with Naturepedic’s waterproof backing.

With Naturepedic’s Breathable line, you have the choice between either their lightweight wavesupport™ inner core, or a traditional coil spring.

The lightweight core (recommended here) is made from food grade polyethylene plastic. This firm inner core is then surrounded by organic cotton batting, plant-based PLA material (made from non-GMO sugarcane) on the toddler side, a wipe-clean waterproof layer (Naturepedic uses non-GMO sugarcane-derived food grade polyethylene for waterproofing), followed by the 3D breathable sleep pad, made from certified organic cotton.

The breathable pad is an independent unit – you can completely remove it for washing, and can use the mattress with or without it, in the case of middle of the night accidents. You can also get an extra one for situations like these, and just a quick middle of the night swap out.

Worth nothing, the Naturepedic’s Breathable series of mattress is a 2-stage dual firmness mattress. Dual firmness means there is a firm side for infants and a slightly softer side for toddlers, meaning the mattress will grow with your child until they outgrow a toddler bed.

This mattress is organic textile standard GOTS-certified, MADE-SAFE Certified, and Greenguard Gold certified. As with all Naturepedic crib mattresses, this mattress is made in the USA and is free from flame retardant chemicals.

Brentwood Home Wildfern (Nov. 2020 Update: Unavailable)

The Brentwood Home Wildfern mattress truly is mostly all natural, with the benefit of being a waterproof mattress for your baby.

The Runner Up

A 2-stage dual firmness crib mattress, the Wildfern is suitable from birth all the way through toddlerhood. Filled with organic coconut coir and natural latex, the mattress has a waterproof cover achieved with food-grade polyolefin. With no flame retardant chemicals and Greenguard Gold certification, there’s no need to worry about off-gassing. Vegan families will love that this crib mattress is wool free. $295, with free shipping

We think the Wildfern is the best organic crib mattress choice for most families. While it’s not perfect, there’s a lot to love about it, including the price: $295.

Brentwood Home is ultra transparent about the “inner bits” of this mattress – organic coconut husk and organic latex. And that’s it – no mystery materials or flame retardant ickiness, and fairly eco friendly.

The Wildfern organic mattress has a waterproof mattress cover, a feature that requires food-grade polyolefin to achieve. Polyolefin is a plastic – the same plastic found in milk carton coatings and food bottles. While we get that some families won’t like this feature, we also believe many will. Crib mattress “accidents” are no joke, after all, and an easy to clean mattress for your baby will also make your life easier as a parent.

The Brentwood Home Wildfern is also a great choice for vegan families, as it’s wool-free. You can also be happy to know this mattress is made in the USA in LA. This mattress is Greenguard Gold certified too!

You can read our more detailed review of the Wildfern here.

Naturepedic Classic Lightweight

The Most Affordable

Naturepedic’s Classic line is a top seller (formerly referred to as the Naturepedic No Compromise or Organic Cotton Classic line). Offering a great blend of affordability and safety, we think a ton of families are going to love this choice for baby!

Naturepedic’s Classic line of organic mattresses includes Lightweight and 150 innerspring. Of the Lightweight option, you can choose between single firmness (firm on both sides) or dual firmness (with a plusher toddler side).

Personally, we think the lightweight, dual side is the best buy at $289, as a 2-stage crib mattress will last you a lot longer, especially once your little one develops opinions and demands a softer mattress to sleep on!

The construction and materials used in this mattress are largely the same as the Breathable line, without the benefit of the removable breathable pad.

Some things are absolutely the same thought, such as the peace of mind that comes with no flame retardant chemicals or use of questionable materials, like memory foam. And it still has wipe clean waterproofing, making it easy to clean after middle of the night accidents.

Naturepedic also has a great organic mini crib mattress. You can see it on their website, here.

Nook Pebble Pure

The Upgrade

Covered in the gorgeous and practical Pebble Wrap, the Nook Sleep Pebble Pure is organic, non-toxic, earth-friendly and breathable. The inside consists of organic coconut coir, natural rubber tree latex, and organic wool. The signature Pebble wrap is made of organic cotton, eucalyptus fiber, an organic cotton/non-toxic poly blend, zinc, and a nylon zipper. The cover is removable and machine washable, and can be used without sheets.

For design-forward families, it’s hard to go wrong with the Pebble Pure. If you want an organic crib mattress that’s functional, healthy, and downright beautiful, look no further.

Firstly, it’s covered in Nook’s signature Pebble Wrap, which can be used without sheets. The wrap is made from organic cotton, eucalyptus fiber, an organic cotton/non-toxic poly blend (which adds to the machine washability), zinc, and a nylon zipper. And the eucalyptus fiber provides natural moisture resistance, and the “pebbles” design adds to breathability of the mattress.

The inside of the mattress is made of coconut coir, natural latex and organic wool.

The Nook Pebble Pure is priced at $419, comes with a lifetime warranty with proof of purchase, and a 100-night sleep trial. Nook offers free shipping and returns within the continental USA.

Naturepedic Breathable 252

Best Innerspring

Naturepedic is definitely cleaning up on this list, but with fairly good reason – it’s one of the most recognized brands in the organic mattress world (they also make adult mattresses, btw!)

The Organic Breathable 252 is the sister mattress to the Organic Breathable Lightweight. It’s more or less identical, with the exception of the inner core. In this model, the company uses 252 innerspring coils, instead of the wavesupport™ inner core.

Other than that, it’s still got all the benefits of our winner, including a breathable pad, safe waterproofing and materials, credible certifications, and comfort of 2 stages for your growing little one.

Runner Up: Best Innerspring Organic Crib Mattress

Organic Innerspring Crib Mattress

Made of breathable, all-natural coconut fiber, a heavy duty coil innerspring, and a quilted cover with natural organic wool and cotton. The Emily mattress is GREENGUARD Gold Certified as well as GOTS and GOLS certified organic. Handmade to order with a 100-night sleep guarantee, and no plastic whatsoever.
Learn More

We love that the Emily Crib Mattress is hand-made in the USA from non-toxic materials. It uses all organic and all-natural materials (apart from the innerspring coils).

The GREENGUARD Gold Certification means you don’t have to worry about VOC off-gassing. And the 100-night sleep trial and 7-year warranty means you can buy this mattress with confidence.

The Emily mattress provides a safe, firm sleep surface for a newborn. It combines an innerspring design with GOTS certified organic coconut coir. GOLS-certified organic natural latex is used to bind the coir. And the quilted cover is made from organic cotton and organic wool.

For families that don’t mind sacrificing waterproofing to get a plastic free crib mattress, the Emily is a great choice. With the Emily, parents are free to choose which waterproofing method makes sense for their family. This means the decision remains in your hands – not a company’s.

We also love My Green Mattress’ commitment to ethical and environmental production methods.

Overall, the Emily Crib Mattress is a great innerspring organic crib mattress. It uses all natural and organic materials (with the exception of the innerspring coils!), and comes from an ethical, environmentally-minded company.

The All Natural: Best All Natural, No Plastic Organic Crib Mattress

The Best Truly All Natural Crib mattress

Made from organic coconut fibre, organic wool, and unbleached natural cotton, with no plastic whatsoever. Fits a standard USA crib, and comes with a 5-year warranty.
Learn More

The organic crib mattress market is filled with crib mattresses that are semi-organic, at best.

The Brentwood Home Wildfern is our top choice for most families, but it does use a thin food grade plastic coating to achieve waterproofing. The Emily Mattress uses innersprings – there’s no such thing as organic steel! And the Nook Pebble Pure uses a cotton/poly blend in the pebble wrap/cover.

There’s nothing wrong with this, per se – these mattresses are all well-certified as safe and healthy choices for your little ones.

However, we also understand that some families will want an all natural crib mattress with no plastic whatsoever. Enter Naturalmat’s Coco Mat.

The Coco Mat is made from simple materials that you can pronounce: organic coconut fibre, organic wool, and unbleached natural cotton. Quite uniquely, it doesn’t have any plastic products in it, although you can add their mattress protector if you want waterproofing.

It measures 52” x 28” x 6”, which is a standard crib size in the USA, and has a 5-year warranty.

The All Natural Latex: Best Organic Latex Crib Mattress

All Natural Latex

An all natural organic latex crib mattress, Soaring Heart also uses organic wool and organic cotton. No mystery materials give parents confidence when choosing this option!
Learn More

Soaring Heart is another company that makes an all natural organic crib mattress. Instead of using a coconut inner mattress, like Naturalmat, Soaring Heart uses all natural organic latex, along with organic wool and organic cotton cover. No fire retardant chemicals here, folks. Worth noting it’s also not waterproof, meaning you’ll probably want an extra mattress cover or pad to protect it.

Soaring Heart’s organic latex is firm, making it suitable for newborns and older babies. It’s single sided, meaning there isn’t an infant side (which is firm to reduce risk of sudden infant death syndrome) and a toddler side – there is only a firm surface suitable for both.

This crib mattress measures 28 ⅝” x 52 ⅜” x 3 ½” and fits in US standard cribs. Their mattresses come with a 20-year-warranty and 30-day comfort guarantee.

Organic Crib Mattress Buying Guide

Materials & Chemicals

Unfortunately, some crib mattresses are a source of harmful chemicals in the home. While not all chemicals are harmful, many of them are. Personal care products, cleaners, bedding, and baby and childrens’ products such as car seats, bath toys and baby bath tubs can all contain chemicals that are harmful to our kids’ health and the environment.

When shopping for the baby crib your little one is going to sleep in, we recommend starting with a non-toxic crib, and adding in a safe mattress and bedding.

But what does that mean, exactly, and what materials and chemicals should you look for (and look to avoid)?

Polyurethane Foam

Polyurethane foam is one of the most common crib mattress components (and adult mattresses, too).

To make polyurethane foams and memory foam, manufacturers react diisocyanates (methylene diphenyl diisocyanate [MDI] and/or toluene diisocyanate [TDI]) with polyols and water. It may also contain other chemical catalysts, blowing agents and flame retardants.

If your eyes glazed over a bit here, try to stay awake.

Flexible polyurethane foam is in a lot of your baby’s gear – including pieces she spends the most time with. We’re talking her crib mattress, car seat, nursing pillow, and more.

In “normal” flexible polyurethane foam (as opposed to plant-based foam), both the polyols and the isocyanates are petroleum-based.

In other words, it’s made from non-renewable resources. 

Besides being environmentally problematic, polyurethane foam can also be problematic for your baby’s health. If manufacturers use excess TDI, they can remain in the foam as unreacted isocyanates

TDI is a probable carcinogen and the USEPA notes that exposure to isocyanates can cause asthma; lung and skin damage; respiratory problems; and eye irritation.

Certipur US certified foam is likely a better option, but certainly doesn’t fit the bill of being an organic mattress option!

Our Grade: Fail (avoid if you can)

Polyurethane Foam Deserves to Fail

If possible, avoid buying products for your baby that use polyurethane foam. Choose healthier alternatives like coconut coir, natural latex, organic wool, and unbleached organic cotton. If you don’t have a choice, look for products that are Greenguard Gold certified, and those that use CertiPUR-US certified foam. CertiPUR-US certified is an independent certification.

Plant-Based Foam or Soybean Foam

Plant-based foam is foam in which some or all of the polyols used in the foam come from plant sources. Soy is the most commonly used plant in creating foam, which is why you’ll most often see it marketed as soybean foam or soy foam. 

Where as petroleum-based polyols can be replaced with plant-based polyols, diisocyanates cannot be. Even in plant-based foams, therefore, a considerable portion of the raw ingredients are petroleum-based.

Plant-based foam is likely better for your family and the environment, but marginally so. While it’s often marketed as an environmentally-friendly solution, we think there are far better alternatives, including natural latex, coconut coir, organic wool, and unbleached organic cotton.

Our Grade: Fail (avoid if you can)

Plant-Based Foam is Mostly Greenwashing

Soybean foam, soy foam, plant-oil foam – from what we can tell, it’s all a different way of saying the same thing. And at the end of the day, “foam” is the most important word. If you can, avoid plant-based foam. And if you can’t, look for products that are Greenguard Gold certified as well as those that are CertiPUR-US certified.

Polyethylene Terephthalate (PEET or PET)

Polyethylene terephthalate is a food grade plastic derived from hydrocarbons. 

When used in food and other packaging, it’s most commonly known as PET or PETE, and is identifiable by the #1 recycling symbol. When used as a textile, it’s known as polyester. 

PETE is generally considered to be one of the “safer” plastics available, and leading health authorities agree PETE is generally safe.

However, it has also been found to leach antimony (a possible carcinogen used as a catalyst during manufacturing) into bottled water. A number of studies have also found polyester clothing can expose wearers to antimony. 

From an environmental perspective, PETE is not biodegradable and is energy intensive to manufacture. However, it is recyclable, and very lightweight, which means it requires less energy during shipping. 

Studies investigating the relationship between SIDS and antimony have shown no link between the two. 

Put succinctly in the Journal of Environmental Monitoring:

“Antimony, which is normally present in domestic environments, has also been studied as a possible cause of cot death syndrome (SIDS) but extensive investigations have not confirmed this.”

Our Grade: Okay (Likely Okay for Health; Not Great for the Planet)

PET Makes the Grade (But Still isn’t Awesome)

While PET(E) is probably a safe crib mattress filling for your baby, it’s made from a non-renewable resource. If you purchase a crib mattress that uses PETE, look for one that uses recycled PETE, thereby helping to postpone the plastic’s introduction to our landfills and giving it a second lease on life.

Harmful Chemicals in Crib Mattress Waterproofing

Anyone who’s had a baby or young child knows how often middle-of-the-night accidents lead to middle-of-the-night clean-ups.

And because manufacturers understand the need to protect the inside of the mattress against urine and – ahem – other – messes, it’s long been the wisdom to use waterproof covers and layers in crib mattresses. 

Some crib mattresses are enveloped entirely in a waterproof cover, while others make use of a waterproof crib mattress pad or waterproof layer near the surface of the mattress.

With benefits of waterproofing, come some major drawbacks for your little one’s health. This is primarily because of the chemicals and materials used to achieve a waterproof crib mattress.  

Polyvinyl Chloride (PVC), Phthalates and Phthalate Alternatives

PVC, more commonly known as vinyl, is a popular choice for waterproof crib mattress covers.

And one of the major problems with PVC is the phthalates (and phthalate alternatives) that come with it. 

Without phthalates, PVC is a hard, rigid plastic. By adding phthalates and other plasticizing chemicals, manufacturers transform that rigid plastic into one that’s soft and pliable – like your raincoat, shower curtain, or inflatable plastic toys. 

The problems with phthalates are many. They can vaporize and off-gas into the air in your home. They can also “disconnect” from the plastic they’re added to and attach to household dust. Babies (all of us, in fact) can also absorb phthalates through their skin. 

Phthalates and their alternatives come with a number of demonstrated and suspected nasty health and developmental effects. 

They’re known endocrine disruptors and are suspected to contribute to endocrine diseases such as breast cancer and obesity, are correlated with asthma, neuroatypical disorders such as autism, low IQ, male reproductive development issues and more.

While some phthalates are banned in the United States for use in children’s toys and care articles, as well as some banned from children’s toys that can be placed in a child’s mouth, others are still permitted. 

Further, with the ban on some phthalates, there’s been a corresponding uptick in the use of phthalate alternatives, about which less is known. 

Our Grade: Fail (avoid if you can)

Keep PVC and Plasticizers Away from Your Family

There are still a lot of knowledge gaps regarding phthalates and phthalate alternatives and their effects on human health. What we know is concerning enough to avoid these nasty chemicals.

Other Harmful Chemicals in Crib Mattresses

Chemical Fire Retardants and Chemical Flame Barriers

Flame retardants are a significant problem across a range of consumer products, including anything made of flexible polyurethane foam (foam and memory foam mattresses, car seats, upholstered furniture) and electronics.

Flame retardants have nasty health effects, having been linked to a range of diseases and disorders, from hyperactivity to early puberty to cancer. 

And unfortunately, researchers have found chemical flame retardants in a range of products meant for babies and young children: car seats, baby carriers, changing table pads, infant crib mattresses, nursing pillows, strollers, toys….

Interestingly, not all polyurethane foam products contain fire retardants. Duke University’s Foam project analyzed 2215 samples of foam sent into the lab by members of the general public. They’re findings are illuminating:

  • In approximately 9% of samples (203 units), researchers detected two or more fire retardants.
  • In approximately 41.5% of samples (919 units), researchers detected only one of the fire retardants tested for.
  • In almost half of the samples (1093 units, representing roughly 49%), the researchers didn’t detect any of the flame retardants tested for.

Despite this, further research shows that fire retardants are so common in our lives and environment, they now show up in some very unwelcome places, from our supermarkets to our breast milk

Our Grade: Fail (avoid if you can)

Look for Products That Use Natural Flame Barriers

As parents, we personally advocate an “abundance of caution” approach. Given that natural and non-toxic flame barriers exist – coconut coir and wool are two examples – it makes sense to look for a crib mattress that doesn’t contain harmful chemical flame retardants. 

Volatile Organic Compounds

Furniture, building products, glues, paint, cleaners, air fresheners and other day-to-day products can all release volatile organic compounds (VOCs) into the air in our homes. 

Some VOCs fit into the other classes of chemicals discussed here. For example, the class of fire retardant known as polybrominated diphenyl ethers are VOCs, as are toluene diisocyanates, used in flexible polyurethane foam. 

VOCs are linked to cardiovascular disease, allergies, fatigue, asthma, reproductive disorders, kidney and liver damage, and cancer  – among other things (source). In other words, it’s worth taking them seriously and trying to reduce VOCs in our homes. Especially considering the fact that young children may be more susceptible to the ill effects of VOCs than healthy adults.

If you’ve heard about mattress off-gassing, you’ll be interested to know it relates to VOCs. Off gassing is the process by which VOCs are released from the chemicals inside your mattress into the air.

And it’s not just the crib mattress you should consider when it comes to VOCs. Cribs that use manufactured or composite wood, and those that use certain paints and finishes, will also emit VOCs. As such, we also recommend you buy a non toxic crib.

Our Grade: Fail (avoid if you can)

Buy Low VOC Products with Independent Emissions Tests

Greenguard Gold is the gold standard for ensuring a product has low VOC emissions. Only buy mattresses for your baby and family that meet this standard, and choose minimally processed crib mattress materials that are from plants (eg. cotton, coconut, natural latex) or animals (eg. wool) to reduce VOC exposure.


Formaldehyde is a VOC you’ve most likely heard of before. Being exposed to formaldehyde can cause skin, eye, nose and throat irritation, and may cause cancer at high levels. 

Unfortunately, we’re all pretty much constantly exposed to small amounts of formaldehyde, According to the USEPA:

The primary way you can be exposed to formaldehyde is by breathing air containing off-gassed formaldehyde. Everyone is exposed to small amounts of formaldehyde in the air that has off-gassed from products, including composite wood products.

At room temperature, formaldehyde is in gas form. Which means if you’re in a room with formaldehyde, there’s a good chance you’re breathing it in.  

You’ll find formaldehyde in composite wood products like hardwood plywood, particleboard and medium-density fiberboard, in building and insulation materials, in glues, paints, coatings, in some cosmetics and medicines, in dishwashing liquid and fabric softener, and in fertilizers and pesticides, for example.

Our Grade: Fail (avoid if you can)

Formaldehyde Belongs in the Lab, Not the Nursery

Look for crib mattresses that don’t use adhesives and glues, which may be a source of formaldehyde. You can also look for UL Environment’s Formaldehyde free verification.

Safe Non Toxic Crib Mattress Materials

Now that you know what NOT to buy, let’s turn our attention to some non-toxic crib mattress materials, and organic crib mattress materials, to look fo when shopping.

First, look for a crib mattress constructed from non-toxic materials. Generally speaking, non-toxic materials mean minimally processed materials from a plant or animal. However, when it comes to crib mattresses, innerspring coils are also a great choice, so long as they’re not used in combination with toxic crib mattress fillings and chemicals.

Additionally, look for materials that are also independently-certified as organic, where applicable. This means your little one won’t be sleeping on “natural” materials that happen to be treated with pesticides and other harmful chemicals during growing and processing.

Organic Cotton

Conventional cotton is environmentally and socially problematic. It’s a pesticide, land, and water intensive crop, and much of the world’s cotton likely relies on forced labor. Processing is also problematic, as the dyeing, bleaching and finishing processes involve various levels of hazardous chemicals. 

To be friendly to your baby and the planet, look for crib mattresses that use Global Organic Textile Standard (GOTS) certified organic cotton. This certification applies across the production and processing chain.

Our Grade: Pass

When Buying Cotton, Look for GOTS Certified Organic

Organic cotton means you can rest easy, just as your little one does! Safely grown and processed, organic cotton is a safe and non-toxic option for your little one’s crib mattress.

Coconut Coir

Coconut coir is a firm and somewhat spongy material made from the hairy outer shell of a coconut. You probably have coir (pronounced core) in your house already: hanging baskets are often lined with coir, as it makes for great potting, many doormats are made from coir, and some rope, as well.

The benefits of using coir in a crib mattress are many! 

  • It’s naturally moisture resistant and breathable, which also means it’s great at resisting mold. 
  • It’s firm, making it a natural choice for a baby crib mattress, which must be firm for safety reasons. 
  • It’s relatively hypoallergenic, and is good at keeping dust mites under control.
  • It’s a good temperature regulator, and will keep your baby cooler in summer than most foam mattresses.
  • Coir can be an “earth friendlier” crib mattress choice, since it helps to ensure the entire coconut is used.

A word of warning: when shopping for a crib mattress that uses coir, make sure the coir is bound with natural tree rubber latex, rather than synthetic latex. 

Our Grade: Pass

Coconut Coir is a Firm, Natural Alternative to Foam

Ideally, look for organic coconut coir, and ensure the coir mats aren’t covered in synthetic latex.

Natural Latex

Natural latex is a tree sap collected from rubber trees. Much like maple trees are tapped to collect maple syrup, so are rubber trees tapped to collect natural latex. 

When shopping for a crib mattress that contains natural latex, it’s wise to be aware of some misleading marketing terms, and take a second look at anything claiming to use 100% natural latex. 

100% natural latex – and terms like it – are common in crib mattress marketing. However, it can be confusing to figure out exactly what this means. 

In fact, no processed natural latex is “100% latex.” Additives used during production mean the finished latex product is between 90% and 97% latex (with the remaining percentage made up by additives). The Global Organic Latex Standard (GOLS) specifies certified products contain more than 95% certified organic raw material. 

However, you still want to look for these kinds of terms. Because they generally mean the latex used in the product is 100% natural, rather than a natural-synthetic latex blend, which is also common.

Our Grade: Pass

Natural Latex is a Sustainable and Safe Option

Natural latex is a firm, safe, and relatively eco-friendly choice, and a much better option than foam. If you’re concerned about latex allergies, be sure to talk to your paediatrician!

Organic Crib Mattress Buying Guide: Considerations

All of the company’s we’ve chosen to feature are reputable. So what else should you consider when buying an organic crib mattress?


In the world of organic crib mattresses, there are a crazy array of independent third-party certifications out there. If this is your first time choosing a crib mattress, all the acronyms may feel a bit mind boggling. 

These are some of the most common certifications you’ll come across when shopping for an organic crib mattress.

GreenGuard Gold

GREENGUARD Gold Certification is an independent certification that measures VOC emissions from products.

When a product is GREENGUARD Gold certified, this means it is a low emitting product. The specific values are no greater than 1/100 of currently published ACGIH® Threshold Limit Values (TLVs) and no greater than one-half of California’s Chronic Reference Exposure Levels (CRELs).

GREENGUARD Gold certified products are safe for use with sensitive people and in sensitive settings. In other words, with children, the elderly, and education and healthcare facilities.   

We also suggest you purchase a greenguard certified and non-toxic crib, in addition to the crib mattress.

Validated Formaldehyde Free

Like GREENGUARD Gold, this independent certification/validation scheme is run by UL Environment. 

The Formaldehyde Free validation means a product is independently verified to be free from formaldehyde and formaldehyde precursors. One problem with formaldehyde is the fact that many products don’t actually contain added formaldehyde. However, they do contain chemicals that, when mixed together, create formaldehyde. This means companies can say their products are formaldehyde free, even if those same products emit formaldehyde. 

The UL Formaldehyde Free verification ensures your product doesn’t contain AND won’t emit formaldehyde.

Products that hold the Validated Formaldehyde Free label must also hold GREENGUARD Gold Certification.  

MADE SAFE® Certification

The MADE SAFE® program is a hazard-based independent screen that checks that products are made without known toxic chemicals. 

Getting the certification means a product has been independently screened. They look for known behavioural neurotoxins, carcinogens, developmental toxins, endocrine disruptors, fire retardants, heavy metals, neurotoxins, high risk pesticides, reproductive toxins, toxic solvents, and harmful VOCs. 


GOTS stands for Global Organic Textile Standard and GOLS stands for Global Organic Latex Standard. Both standards certify ecological and social aspects of the entire product supply chain, from processing to distribution.


The Standard 100 is an independent verification for textiles. It tests all aspects of the textile for human and ecologically harmful chemicals. According to their website, if a textile carries the Standard 100 certification, “the article therefore is harmless in human ecological terms.” 


Brentwood Home

Brentwood Home offers one organic, all-natural crib mattress, The Wildfern. At the heart of the company is an ethos of protecting your baby’s and the planet’s health.

All Brentwood Home crib mattresses are free-from fire retardants. The company is transparent about the materials they use in their mattresses. In their own words, they use:

“a combination of organic, nontoxic, and natural materials with no chemical retardants, phthalates, ozone depleters, or heavy metals.”

The Wildfern is Greenguard Gold Certified.

My Green Mattress

My Green Mattress is a company with a great story to tell. Parent-led, Tim Masters started the company when his daughter Emily was born. Emily suffered from a number of environmental allergies, so Tim built a natural crib mattress to help alleviate her symptoms. That’s how the Emily Natural Crib Mattress was born – as a mattress good enough for Tim’s own daughter.

All My Green Mattress products (they also make mattresses for adults) are handmade in Lagrange, Illinois. The factory is GOTS/GOLS certified, and the products contain only organically grown, harvested and processed materials. They’re made in an environmentally and socially responsible manner.

Importantly, all their products are free-from harmful and potentially harmful chemicals. This means no formaldehyde, flame retardants, or VOCs, which often come hand-in-hand with materials like polyurethane foam and polyester.

My Green Mattress has multiple 3rd party certifications. They use GOTS certified wool and cotton and GOLS certified natural latex. They have a OEKO-TEX certificate for textiles. And they hold an Eco Institute Certificate, UL compliance, Carbon Neutral certificate, and Greenguard Gold certifications.

Nook Sleep

Nook is another parent-led company born out of the birth of the founders’ own children. Back in 2008, there weren’t a lot of organic crib mattresses on the market. Their own crib mattress shopping experience left them disappointed, and they figured they could do better!

Nook makes a range of really cool mattresses and other products. Not all of them are organic (the Pebble Pure is their all-natural and organic crib mattress). However, those crib mattresses that aren’t organic have really cool features. The Dream Cotton uses upcycled denim, and the Pebble Lite, uses recycled PETE bottles, for example. 

Nook’s certifications include: Greenguard Gold, GOTS, OEKO-TEX, CertiPUR-US® (for foam products), and FSC certification.


Naturalmat has been making mattresses since 1999. The company started out with a mission to change the industry by creating mattresses with natural (instead of synthetic) materials. And without any chemical additives, to boot.

Today, they claim ALL the ingredients that go into their products are 100% natural and from a sustainable source. Taking it a step further, Naturalmat mattresses are 100% biodegradable at the end of their life. 

The mattresses are handmade in Devon, England (Naturalmat is a UK company, but you can buy them in the US).

Naturalmat hasn’t gone “certification wild” like some of their organic crib mattress competitors. However, they’re pretty darn transparent on their website. No glues, no fire retardant chemicals, all natural and organic. 

Soaring Heart

Soaring Heart is another company that’s easy to love. The company sources materials from small farms and ranches. And they choose suppliers that operate according to sustainable principles and strong animal welfare practices.

Soaring Heart is also super transparent. You can actually order a box with small samples of all the materials used in your baby’s crib mattress!

Their mattresses are made in Seattle, and are safe and chemical free. According to the company, they’re all about keeping it simple with all organic, toxin-free materials. We can get behind that! 

Soaring Heart holds multiple certifications. They are GOTS and GOLS organic certified, USDA organic, Oregon Tilth organic certified, and Texas Department of Agriculture certified organic cotton.

Shipping, Warranties, and Satisfaction Guarantees

Most of the companies we’ve listed ensure their mattress comes with some sort of satisfaction guarantee and warranty. However, it’s worth double checking before hitting the buy button. Policies change. While we do our best to stay on top of changes, we can’t guarantee info is still up to date.
