The media is telling us every day that we need to stop using single-use plastics, releasing toxic materials and start thinking more long term.

Slowly but surely the brands are starting to look away from cheap, chemically packed materials and making way for greener alternatives in their chain of production. We have put together a guide to some of the top natural and organic mattress options available right now in the UK, as well as clarifying the differences between an organic mattress and a sustainable mattress.

Experts Advice

Whether you want an organic mattress for health reasons or environmental ones (or both), there’s more to the decision-making process than a quick glance at the manufacturer’s label. If only it was that easy!

First, look for accreditation to back the claim to be organic – GOTS is one of the most common.  Which materials are certified organic? Probably not all of them, so what percentage? What other materials have been used? Bear in mind that while organic cotton has less environmental impact than regular cotton, hemp and bamboo boast strong eco-credentials too.

Second, if sustainability is your motivation, consider whether organic is the best – or only – criteria to judge this by. Other certification schemes, including Fairtrade, can also indicate better-than-standard environmental practices. Likewise, durability is an important factor. The longer your mattress lasts, the lower its impact on the planet because it won’t need disposing of or replacing as quickly.

Mattress Material History

If we take a look back we can see that history has a way of repeating itself and, same as in fashion, trends return. The innerspring bed was invented in the 1870s by German Heinrich Westphal and although it took over 60 years for them to become popular, the metal springs are today one of the most common components in mattresses.

Back then, the spring mattresses were filled with natural materials such as wool, hay and down, not too different from the materials we can find in today’s organic and natural mattresses. However, as often happens, the trend changed and other materials entered the market.

John Boyd Dunlop started experimenting with latex together with scientist E.A. Murphy, trying to transform it into a foam. The story says that Murphy used his wife’s cake mixer to whip the latex into a foam. The first latex mattress was introduced to the market around 1930 and, fast-forwarding ninety years, Dunlop latex is today one of the most popular materials in natural and organic mattresses.

Latex is whisked and baked into foam

Latex was however not as cheap to produce as its latest competitor, the polyurethane foam, which quickly became very popular. NASA took it to the next level in 1970 when they developed a “slow spring back foam”, designed for crash protection and more comfortable seating for airlines. After releasing the technology around the 80’s it did not take long before the today known as memory foam mattress was born.

There was also an intense trend of water beds booming in the late 1980s but it was short-lived, likely due to the complexity of having to fill it up, or even worse, trying to move the bed. Not to mention the problems that could occur if there was a leak.

Mattress Materials Today

Now that we have covered the most recent history we can see that some trends have been coming and going, such as latex mattresses. Others, like water beds, seem to be gone (at least for now) but there is one material that has been very consistent since it was introduced on the market - the memory foam.

Memory Foam

Given the low production cost and the many good qualities that it has, it is no surprise that this is such a popular material. Memory foam mattresses have changed the lives of many people suffering from back problems thanks to their pressure-relieving abilities and the cradling comfort they provide. But they do come with one, very large, exclamation point - they tend to contain a lot of chemicals that can sometimes be harmful both to humans and to the environment.

An organic mattress should not contain any dangerous chemicals

If you have ever purchased a memory foam mattress you may have noticed that your new mattress might smell a bit funky the first few days. This phenomenon is called “off-gassing” and occurs when the VOC’s (Volatile Organic Compounds) break down. When coming into contact with air these compounds release an unpleasant smell that can sometimes worry people.

It’s worth noting that VOC’s are common in a wide array of products that most households have, such as non-stick pans, cleaning products, printers and furniture, and not something we need to be overly worried about. However, a study✓ shows that mattresses can emit higher levels of VOC during sleep, reaching concerning levels for children and infants.

This naturally makes people have reservations about spending a third of their lives breathing in these gasses that are commonly found in both the foam and the adhesives of the mattresses.

No to toxic memory foam

Do All Foam Mattresses Contain Harmful Chemicals?

Not all types of foam mattresses are bad for us.  Many of the bigger mattress brands are certified by organisations such as CertiPUR-US that ensures that the foam does not contain any ozone depleters, heavy metals, dangerous flame retardants and that they have low VOC emissions (less than 0,5 parts per million).

Up And Coming Organic And Natural Mattress Materials

Although many people are aware that foam mattresses are not great for our health, they are still widely popular. But luckily for those who have sworn off memory foam, there are plenty of organic and natural mattress materials that are back in fashion, as well as new players on the field.

Latex

Our previously mentioned friend John Boyd Dunlop’s method is today one of the two standard methods of making latex foam. The scientist’s wife’s cake mixer has been upgraded but the theory is the same: infusing the latex with air and then baking it. This creates a more breathable foam than the rather compact polyurethane which tends to get warm at night.

The latex comes from the Hevea Brasiliensis tree, more commonly known as the rubber tree. These trees are tapped and the white, milky substance that is collected is the liquid latex that is later turned into latex mattresses. The other method is the Talalay method which is slightly more complex than the Dunlop method as the latex is being whipped, vacuum-sealed to expand, frozen quickly and then baked.

The difference between these two methods is that the Talalay latex is more breathable and fluffier, which makes for a great addition to the comfort layers in a mattress. The Dunlop latex is denser which makes it suitable for the base layers of the mattress, although many brands also use it for the comfort layers as it is also cheaper to produce than Talalay latex. 

Talalay latex foam is common in organic mattresses

Other Materials In Organic Mattresses

Other materials that are frequently used in organic and natural mattresses are:

  • Wool - A great, organic filling that is naturally fire retardant and has the ability to keep you warm in the winter and cool in the summer.
  • Bamboo - Bamboo can be used in different ways in mattresses. It can give an incredibly smooth finish to covers, or enhance breathability when infusing foam with bamboo charcoal.
  • Coir - This organic material, also known as coconut fibre, is becoming increasingly frequent in the support layers of organic mattresses. The fibres act as micro coils and are often used to substitute steel springs.
  • Horsehair - Similar to the coconut fibre, the curled hairs give a springy feel and are great at wicking away moisture.
  • Cotton - Commonly used in organic and natural mattress covers thanks to its breathability.

Did you know?
There are various studies✓ and research articles✓ pointing at the many benefits of organic cotton farming versus conventional cotton farming in countries like Turkey and India. However, due to the lack of financial support, the transition period between the two methods becomes a major obstacle.

What Is An Organic Natural Mattress?

Don’t be fooled by brands throwing the terms “organic” and “natural” around as if their life depended on it. A mattress that has an organic cotton cover does not automatically make it an organic mattress. It is important to look at the materials and their certifications to define how organic it actually is.

Some mattresses, such as spring mattresses, simply cannot be 100% organic as the steel springs are not something you can grow. That being said, don’t be discouraged, the rest of the materials could potentially be fully organic and the steel could be recycled or recyclable, making it a great mattress anyway.

Approved organic natural mattress

Instead of buying into greenwashing, look for labels and certifications such as GOLS and GOTS that will ensure the quality of the materials used and make sure that as many components as possible are, in fact, organic. Another well known British organisation you can look for to ensure quality in your mattress is the Soil Association.

Pro Tip!
Some brands offer an old mattress disposal service to ensure that your previous mattress doesn't end up in a landfill when you buy your new one. Make sure to look for this when deciding on your new mattress.

Is My Organic Mattress Also Sustainable?

Not necessarily. While the materials in your mattress may be organically grown, meaning that no harmful chemicals have been used in the process, it does not mean that they have been sustainably sourced or that the mattress has been produced in a sustainable way. A sustainable mattress requires more boxes ticked than just containing organic materials, so in order to know if your mattress is sustainable, you need to look closely at the entire process.

Look closely to see if a mattress is sustainable

Why Should I Get An Organic Mattress?

  1. Organic mattresses are generally hypoallergenic, anti-bacterial and dust-mite resistant, which is great for people prone to allergies or asthma.
  2. Organic mattresses often come with a higher breathability than for example memory foam mattresses which can help regulate temperature. This can make them a good option for hot sleepers.
  3. They are kinder to the environment compared to many other mattresses.
  4. Natural materials are often more durable than synthetic ones, meaning that you will enjoy your mattress for an even longer time.

The Downside To Organic Mattresses

There are not many negative things to say about organic mattresses but to name a few they can be a bit more expensive than standard mattresses and the options are more limited. Then again, if you do your research well and invest in a high-quality organic mattress it might last you for many years to come.

What is an organic mattress?

An organic mattress is a mattress made of materials that are organically grown, meaning that no pesticides or other harmful chemicals have been added to the process. Some examples of these materials are organic wool, cotton, latex, coconut fibre and horsehair.

Where to buy an organic mattress?

Not all brands offer organic mattress options but some do. Before trusting their word for it, make sure to look for accreditations that ensure that the materials used have, in fact, been organically grown.

Why getting an organic mattress?

An organic mattress is beneficial both for the sleeper as it contains natural materials that are often hypoallergenic and anti-bacterial, as well as for the environment due to the lack of harmful chemicals.
