What is an organic mattress?

First thing's first:

What exactly is an organic mattress?

Marketing terms like organic, natural, non-toxic, and eco-friendly are often thrown around, but it isn't easy to ascertain what these mean.

And just because a mattress is advertised as organic, it doesn't necessarily mean that it is a 100% natural mattress. 🌱

Properties of organic mattresses


If you see a mattress that's been certified as organic by an independent testing authority, then you know it is the real deal. 👩‍🎓

In general, this means the mattress:

  • Is free from pesticides & chemical treatments.
  • Doesn't contain harmful or toxic substances.
  • Supports sustainability & reduces the overall carbon footprint.

While often more expensive, organic mattresses are available in a wide range of different materials, with a range of different properties.

So if you're looking for a high-quality organic mattress, it's possible to find the bed that's just perfect for you. 🥳

What materials are organic mattresses made from?

Mattresses can be made from a wide variety of different materials, but an organic mattress will have to rely on completely natural and organic materials.

Most standard mattresses contain synthetic foam, like polyurethane foam.

Even innerspring or hybrid mattresses usually contain at least one synthetic foam layer!

Foams certainly have their advantages:

While these foams may be certified to be free from harmful chemicals, they are still synthetic.

This is easy to notice when you encounter off-gassing, a chemical smell commonly emitted by bed-in-a-box mattresses when first unpacked. 📦

Choosing biological alternatives

With organic mattresses, these synthetic fillings have to be replaced by natural materials. 🍀

Common organic mattress materials include:

  • Cotton
  • Wool
  • Latex

Other materials that are becoming more and more common include horsehair, hemp, and coir.

Organic mattress materials

To test the quality of a material, you need to consider both:

  • The origin of the material, and
  • how it was cultivated.

This affects the eco-friendliness of the product.

Organic cotton mattresses

Cotton used to be a very common mattress material, but it has since often been replaced by synthetic foam.

This makes sense, of course, as cotton is more expensive.

But many luxury mattresses still contain cotton or cotton covers.

Cotton mattresses have numerous advantages:

  • Natural, unbleached cotton is very durable and likely to last 15 years or longer.
  • Cotton is incredibly breathable & absorbs moisture quite well, helping you sleep better and keeping you more comfortable.
  • Quality cotton mattresses don't contain any chemicals.

Organic cotton mattresses

Organic wool mattresses

Organic wool mattresses are becoming increasingly popular, like the ones from Harrison Spinks. 🐑

Some non-organic mattresses, like the Simba Hybrid Pro, include a top layer of wool to benefit from some of wool's fantastic qualities.


Some advantages of wool mattresses:

  • Wool allows for excellent breathability, which wicks away moisture and keeps your mattress dry & bacteria-free.
  • Organic wool is hypoallergenic and antimicrobial.
  • High-quality wool is naturally flame-resistant, so mattress brands don't have to add any synthetic chemicals.
  • Wool promotes thermoregulation, meaning that you'll feel cooler in summer and warmer in winter.

Organic wool mattresses

Organic latex mattresses

Not all 100% natural latex mattresses are organic.

Brands can term their mattresses 100% natural latex, even if they only contain 85% natural latex. 😱

But of that 85%, 100% needs to be natural latex.

The difference is made up of synthetic latex or mattress fillers.

This can be very confusing. 🤯

To ensure that you have a 100% natural and organic latex mattress, you will have to take a closer look at the product.

You can also rely on GOTS and GOLS certifications (more on this further down) to guarantee the quality of the product.

In the absence of proof, there is a good chance that a 100% natural mattress is not entirely natural. 🥺

Organic latex mattresses have numerous advantages:

  • Organic latex is very sustainable and eco-friendly.
  • It is a naturally firm & dense material, which is great for people struggling with back pain or those of a larger build.
  • Natural latex offers excellent temperature regulation and is antibacterial and dust-mite-resistant.

If you're looking for an excellent 100% natural latex mattress, you can consider the Dunlopillo Royal Sovereign Mattress.


It's an expensive mattress, but it's excellent quality.

Organic latex mattresses

Organic mattress UK certifications

Since mattress brands can be unreliable, it's become imperative to look at mattress certifications. 🤓

If you buy a certified organic mattress that's been tested by independent authorities, you can rest assured that you are indeed getting a natural, organic, and eco-friendly mattress.

There are two popular organic mattress certifications used worldwide. 🌎

These are the GOTS and GOLS certifications.

Global Organic Latex Standard (GOLS)

Certified GOLS latex is produced in an environment where all materials and manufacturing processes meet strict global organic standards.

Global Organic Textile Standard (GOTS)

Certified GOTS materials are produced in an environment where all materials and manufacturing processes adhere to strict global organic standards.

Organic mattress certifications

What about foam certifications?

You're also likely to come across CertiPUR and Oeko-Tex certifications.


CertiPUR-US is a North American quality certification for foams. 🇺🇸

Certified foams have been independently tested in laboratories and certified as safe and responsible products.


Oeko-Tex standard 100 is a label that guarantees textiles are free of toxic products.

This includes toxins for the body and the environment.

Foam certifications

Mattresses can be Certi-PUR-certified and meet the Oeko-Tex standards, but this does not necessarily mean they are natural or organic mattresses.

It simply suggests that they are chemical-free mattresses & do not contain any toxic or harmful substances.

If you're looking for a certified organic or 100% natural mattress in the UK, it's essential to consider the GOLS and GOTS certifications.

What do organic mattresses cost?

While there are dozens of organic and natural mattresses available at different price points, they are generally more expensive than regular mattresses.

But since most organic mattresses are also made of very high-quality materials, they offer unparalleled comfort.

They are also far healthier, and you can rest assured that you're making a good choice for both yourself and your family. 🌱

In the long term, the higher price may be worth it as you're guaranteed to get one of the best mattresses on the market.

You can also consider some budget natural mattresses, but these generally lose shape and stability quickly.


If an organic mattress is out of your price range, and you'd still like to pay attention to what's good for you and the environment, you can also consider certified foam mattresses.

Foam mattresses with Oeko-Tex or CertiPUR certifications are guaranteed to be free from harmful chemicals and toxins.

These may not be natural or organic, but they're one step closer.

Our favourite UK mattresses:

Do organic mattresses meet flammability standards?

To be sold in the UK, mattresses need to meet flammability standards. 🔥

Traditionally, there were two ways to do this:

  • The surface of the mattress is sprayed or soaked in chemical flame-retardants.
  • Flame-retardant foams, which often rely on PBDEs (polybrominated diphenyl ethers), chemicals, and other hazardous materials, are used.

Both of these methods involve the use of toxic chemicals.

Organic mattress fire barrier

The method used by most mattress brands today (natural and standard) is using fibre or fabric barriers to surround the inside of the mattress, where most of the combustible materials are located.

A silica base that wraps around the mattress (between the foam and the mattress cover) is the most common.

It melts in case of fire, smothering the flames. 🧯

Thistle and wool are more natural alternatives, both of which prevent fires in the same way.

Can I buy organic or natural mattress toppers?

If you have a mattress that's just a tad too firm for you, but you don't want to invest in a new mattress, a mattress topper may be a good choice.

Mattress toppers are thin layers of extra padding that soften your sleeping surface and enhance comfort.

Many of the best mattress toppers are made from memory foam.

This is because memory foam adapts so well to the contours of your body and creates a much softer and more comfortable sleeping sensation. 🤗

But, conveniently, mattress toppers made of natural materials are not as uncommon as you'd think.

These may not necessarily be organic, but they are largely natural.

Our favourite natural material mattress toppers:

Organic cot mattresses

While choosing an organic mattress may be an important lifestyle choice for you, it's even more critical when choosing a cot mattress for babies or toddlers.

Organic mattresses allow young children to breathe more easily and avoid the risk of allergies. 🤧

As with adult mattresses, it's important to consider external certifications.

Our favourite UK natural cot mattresses:

Should I buy an organic or natural mattress?

It can be challenging to find a truly organic mattress - and these are often very expensive.

But, if you don't have any budgetary constraints and care about your health and the environment, investing in an organic or natural mattress is a good idea.

You can also look for mattresses with natural fillings, natural fibres, or eco-friendly choices as an alternative.

Frequently asked questions

  • Can I buy organic mattresses on Amazon?

    Yes, Amazon does have a small selection of organic, natural, and eco-friendly mattresses available.

  • How do you know if you should invest in an organic mattress?

    Of course, there are a few obvious cases when you know it's time to invest in an organic mattress, particularly if you're already focused on organic choices elsewhere in your life. 

    But you can also take a look at your old mattress.

    If you constantly wake up with allergies or are feeling unwell, then it may be time to invest in a new mattress that contains more natural fibres.

  • What bed frame should you get for your organic mattress?

    Organic mattresses are usually quite dense and durable, meaning they'll do well on any bed frame.

    We generally recommend slatted frames where the slats aren't too far apart, box springs, or divan bases.
