Get comfortable with our handy guide to the best organic mattresses – from single to super king we’ll help you find the right eco-friendly mattress for you.

Of all the sustainable furniture purchases you can make, choosing a mattress is the most important to get right. After all, the average person spends 26 years in bed, and a good night’s sleep is critical to both our health and well-being.

Luckily for the sustainable shopper, there are heaps of purchasing options when it comes to mattresses. You can opt for recycled, natural, organic or vegan mattresses – wherever your ethical preferences lie.

If you want a mattress that has been made from natural materials that have been grown without the use of harmful chemicals then you will want to opt for an organic mattress.

An organic mattress is one that is made with certified natural materials, such as certified cotton, wool or natural latex, which are grown or produced without the use of chemical fertilisers, pesticides, or other chemical inputs.

Once quite a niche market, thankfully the options for organic mattresses have expanded greatly in recent years, as more and more brands seek to minimise their impact on the environment.

About Snoozel Green

Looking to provide a truly eco-friendly alternative to mattress-in-a-box companies, who mostly trade in synthetic layers of foam and chemical fire retardants, British mattress brand Snoozel Green has proudly achieved that goal.

Its premium eco-friendly hybrid mattresses are handmade with organic natural latex, organic cotton and sheep’s wool for an eco-friendly night’s sleep. These naturally breathable materials are perfect for anyone who sleeps hot.

If you are looking for an organic mattress at a more affordable price point then Snoozel Green is our top choice. Mattresses that have been returned within 30 days and are in good condition are inspected and cleaned. These are then resold as rejuvenated mattresses at a reduced cost – starting at under £500 for a double mattress. This makes it lighter on the pocket compared to other organic options.

About Snoozel Green’s Mattresses

Snoozel Green’s organic mattresses are built with comfort in mind. Combining a full-size pocket-spring system with its natural latex comfort layer delivers the benefits of both latex and springs. This allows you to enjoy the perfect blend of sturdy support from the pocket springs, and contouring comfort from the latex, making the mattress more flexible and durable.


Snoozel Green’s commitment to sustainable materials is impressive. It uses only organic certified natural latex that is sourced from Forest Stewardship Council (FSC) certified sustainably managed rubber tree groves.

This FSC certification ensures that the forest where the latex is sourced from is managed in a way that protects biodiversity, whilst benefiting the lives of local people and workers.

Meanwhile, Snoozel Green’s cotton is certified organic by the Global Organic Textile Standard (GOTS). This is grown and processed in Southern India to the highest organic standards and is unbleached and undyed for the smallest environmental footprint. And even the wool used is also certified organic.

Some mattresses are treated with fire-retardant chemicals. Not in Snoozel Green’s case. Its latex is blended with the natural mineral graphite, which makes it fire retardant without the use of potentially toxic chemicals.

It’s not just chemical fire retardants that Snoozel Green leaves out. It also uses zero chemical adhesives, zero petroleum-based foams, and no bleaches or pesticides. This means your mattress won’t have any nasty pongs.


All of Snoozel Green’s mattresses are ethically made in Sri Lanka, close to where its raw materials are produced. Snoozel Green says that factory employees benefit from free food and accommodation, as well as a wage 20% higher than the market standard.

About Ethical Bedding

Whilst most mattresses are made with wool and other animal-based fabrics, Ethical Bedding’s organic mattresses are entirely vegan-friendly. In fact, Ethical Bedding is the only Vegan Society-approved bedding company on the planet. As such, the NatureCore Luxe mattress is our top choice for vegan-friendly sleep.

Handmade in the UK using carefully sourced and considered ethical materials, and with a tremendous 15-year warranty (the best we’ve found), Ethical Bedding isn’t sleeping on the job when it comes to sustainability.

Ethical Bedding also donates a meaningful portion of its profit to World Wildlife Fund appeals. Plus Ethical Bedding is a member of 1% For The Planet – an international organisation whose members contribute at least 1% of their annual revenue to environmental causes.

It also plants a tree for every order. And as a Certified BCorp, this means that Ethical Bedding adheres to the highest ethical and sustainability standards and that the goals of the company go beyond making a profit. So much so that Ethical Bedding was listed as BCorp’s ‘Best For The World’ in 2022.

About The NatureCore Lux Mattress

With sustainability at the core of Ethical Bedding’s mission, you might be worried that there is a compromise on comfort. Not with Ethical Bedding.

Hand-crafted by experts in the UK with decades of experience in bed design and manufacture, the mattress is packed with 17 individual comfort layers. Here, the luxurious fillings used are designed to mould to your body shape. And with 7,000 pocket springs, these evenly and gently distribute your body weight for a dreamy night’s sleep.


Ethical Bedding has avoided the traditional animal products such as wool, silk or cashmere found in most mainstream luxury mattresses. Instead, it has replaced everything with the most innovative and advanced natural substitutes they can that meet all UK fire regulations.

As such, the NatureCore Luxe mattress is made in the UK using a combination of bamboo, coconut, recycled denim, recycled polyester, bioplastic, organic flax, organic hemp and organic cotton. This gives you a truly sustainable sleep.

And the NatureCore Luxe, like all of Ethical Bedding’s products, is OEKO-TEX® 100 certified. OEKO-TEX® is the international safety standard for textiles, which certifies that every single component of the product, from the fillings and fabric, right down to the thread, has been rigorously tested against a list of up to 350 toxic chemicals.

The mattress is also fully recyclable at the end of its life. With that 15-year warranty though, it will hopefully be a long time before you need to consider this!


Ethical Bedding says that it insists on total transparency within its supply chain. As such, it ensures everyone is paid more than a fair living wage and works in excellent conditions. Ethical Bedding also insists upon the highest accreditations with all of its supply and production partners, carrying out regular checks to ensure compliance.

Ethical Bedding is also National Bed Federation (NBF) accredited. In order to be an NBF-approved member, the company must meet industry-recognised standards. This includes undergoing independent assessment and audit, and the inspection of manufacturing sites to ensure the company is working to best practice.

About Una

If your bed isn’t a standard UK size, or you’re looking for an adjustable organic mattress that both you and your partner can customise to your exact preferences, then check out Una Mattresses.

This German brand has cleverly designed a fully adjustable modular mattress system that we haven’t seen anywhere else. Here six individual breathable organic latex layers can be adjusted at home in just a few simple steps.

What’s even more exciting is that all of Una’s double mattresses and lager allow you to adjust the firmness level on each side of the bed. This means if you prefer a firm mattress, and your partner prefers a soft mattress you can arrange the layers to suit. The pillowtop layer then combines both sides seamlessly. Revolutionary!

This also means you can adjust your mattress to suit your circumstances. So for example, if you have a sports injury, have had surgery or are pregnant, and you need to change how your mattress supports you, then you can quickly and easily alter your mattress to suit.

What’s also to love, is that, unlike synthetic mattresses, you don’t have to air this one out before use. It’s ready to go immediately after delivery, without any chemical smells. This is perfect if all the excitement of arranging the layers leaves you needing a little nap!


Una Mattresses are made from renewable natural latex, which is sustainably extracted from Hevea trees on certified organic plantations in Southeast Asia. This process does not kill the trees, so it helps to promote biodiversity in the region.

The latex is Global Organic Latex Standard (GOLS) certified, which is only awarded to products that contain at least 95% organically certified material

Each individual mattress layer is then covered individually in GOTS-certified organic cotton. These have a colour-coded label stating the firmness rating of each layer – to help you configure your mattress to your perfect tension – and certification information for the organic materials used.

The outer cover is also manufactured from a GOTS-certified organic cotton and wool knitted jersey fabric. This gives the mattress a soft and comfortable surface to give you a great night’s sleep. Meanwhile, reinforced sides give the cover extra strength and durability, so that it can go the distance.

Due to the natural materials used, Una Mattresses are completely recyclable and biodegradable at the end of their life.


Una Mattresses are manufactured in India, close to where the latex is extracted. The organic cotton covers are then handmade in Una’s German workshop, adhering to EU labour standards.

Pros & Cons

Pros: Lengthy sleep trial / Long 10-year warranty / Customisable to meet your needs / Available in tricky-to-find sizes

Cons: Not vegan-friendly due to the wool cover / Not made in the UK or EU / Una won’t recycle your old mattress

The Bottom Line

When it comes to getting a sustainable night’s sleep on a mattress that’s been produced without the use of pesticides and other harsh chemicals, then there are heaps of choices available in 2024.

We’ve gone deeper than just looking at the materials used – looking at both the construction and certifications each brand has – to help you find the right type and brand for you. In fact, we couldn’t dream of any better brands to showcase – from Ethical Bedding’s vegan mattress to Una’s innovative adjustable mattress or Snoozel Green’s hybrid mattress.

The best news is that going organic doesn’t mean you have to sacrifice your comfort. All these options provide the support, breathability, and comfort you could ever need in a mattress.
