The best organic mattresses in 2025

The type of mattress we sleep on each night should be chosen with great consideration. We spend a huge portion of our lives on them–approximately a third! Not to mention it's important that a mattress is of high enough quality to last a good amount of time before it needs replacing. According to The Sleep Charity, this should be done ‘every seven years’. Changing a mattress more frequently than that means its environmental footprint inevitably goes up. Another way to consider a mattress' impact on the earth is by looking at what it is made of. Although synthetic memory foam and hybrid mattresses have become increasingly popular in recent years, we are seeing more and more crafted from mainly natural materials, both traditional (cotton, wool) and unconventional (bamboo, charcoal), that have a responsible environmental focus and aim to reduce waste in the mattress industry.
What is an organic mattress?
Unlike in the food industry, there isn't a specific definition of what makes a mattress organic. For the purpose of this piece, we have selected mattresses that have a basis of or principally include naturally derived and sustainable materials, that haven't been chemically processed. Rather than manmade materials like memory foam, cooling gel or synthetic latex, the focus of the mattresses here is primarily on materials derived from nature. Something to note, however, is that synthetic doesn't necessarily mean bad for the environment: there are some sleep products that also incorporate sustainable fibres made from recycled plastic bottles, for example.
Natural materials like wool have hypoallergenic properties, making them ideal for those with allergies or asthma, or if you have concerns about dust mites. Organic mattresses are generally better for the environment, too, with a focus on sustainably grown, traceable and durable materials, and brands like Naturalmat working hard to eliminate single-use plastic packaging and mattresses going to landfill.
There are brands that specialise in natural mattresses, such as the previously mentioned British company Naturalmat, as well as big brands such as Simba. They make a wide range of mattresses including synthetic memory foam and hybrid options, but they also offer a selection of eco-focused ones that prioritise natural materials. Read on for our pick of the crop.

Best organic mattress overall: The Superb Mattress, £1,950 from Naturalmat (tried & tested)
- Naturalmat's most popular mattress.
- Handmade in Devon with natural materials.
- Lighter side sleepers who find the medium mattresses too firm have a soft choice option, which is rare amongst Naturalmat’s premium competitors.
- When this mattress arrives it may smell of wool but it soon subsides. Some customers love the smell; others are happy when it goes.
- 45 day sleep trial is not as long as some other brands.
- At nearly £2,000 for a double, this is premium quality at a premium price.

The USP of Naturalmat is its commitment to using natural fibres – something sleep scientists consistently find leads to better quality of sleep, thanks to its inherent moisture-wicking and temperature regulating properties. The wool used in Naturalmat mattresses is from Devon sheep, while the natural latex is from the sap of the Hevea rubber tree and is a natural alternative to synthetic foams. Handmade in Devon, the Superb is their most popular model and sits in the middle of their range.
The tension in the medium that I tested overnight is perfect; there was no movement from the mattress overnight, I didn’t dip into any pockets and whatever way you turn, you feel deeply comfortable and supported. It’s so prized that some of the best hotels in the world use this model, from the One and Only resorts to The Hoxton.
Most of Naturalmat's mattresses are delivered in reusable, plastic-free bags. On the occasions when these bags can't be used, they deliver in bags made from carbon neutral bioplastic derived from sugarcane and recycled plastic - these bags are completely recyclable (it may need to be taken to your local supermarket if your council doesn't collect LDPE 4 plastics).
I loved the excellent end of life policy that takes into account the amount of mattress waste we see: when you need to refresh your mattress you can either get it repaired and ‘restuffed’, donate it or recycle it with them. An excellent initiative that will help you sleep soundly.
The mattress may feel more or less firm depending on whether your bed has fixed or sprung flats, respectively. The mattress may feel firmer than expected at first, but should become softer after a few weeks of use. The wool in the mattress may give off a natural smell which should subside after airing out.

- Luxurious pillowtop feature adds an extra element of comfort
- Sustainably minded - use of natural materials and recycled materials, recyclable packaging, endorsed by the Eden Project
- Hypnos are Royal Warrant holders
- 40 night comfort trial is less than many retailers offer
- Pillowtop is not removable
- Expensive
| Hypnos Luxurious Earth 03 Mattress | |
|---|---|
| Care: | No turn mattress |
| Mattress depth: | 32cm |
| Trial period: | 40 night comfort guarantee |
| Guarantee: | 10 years |
| Sizes available: | Single, double, king, super king |
| Type of mattress: | Pocket springs, latex and wool |
| Firmness: | Medium or firm |
| Delivery: | £39 for orders over £100 with 1 item in the basket, £59 for orders over £100 with 2 or more items in the basket |
This mattress has a plush pillowtop sewn in to the design, for an extra layer of comfort. The Luxurious Earth 03 is filled with layers of of organic British wool, natural Talalay latex and Allo fibres, a renewable and regenerative material sourced in the Himalayas. It also contains a material that they call eOlus™, which is sustainable but not natural, as it is created from recycled plastic bottles. The mattress's cover is crafted from a cooling cotton damask, which is chemical free. All packaging is recyclable and the mattress is made in the UK, adding more bonus points for sustainability.
This mattress is particularly deep, so may require deeper fitted sheets. The delivery charge is also rather steep, when many retailers offer free delivery as standard, and the mattress alone is at a high price point.
Best natural latex mattress: Natural Latex 4200 Mattress, £2,099 from Feather & Black
| Natural Latex 4200 Mattress | |
|---|---|
| Care: | Air before use and regularly, do not roll or bend, clean it once a month with a soft brush - do not use a vacuum cleaner, don't flip but rotate from head to toe once a week during the first three months and once every three months thereafter |
| Mattress depth: | 32cm |
| Trial period: | 100 night comfort guarantee |
| Guarantee: | 10 years |
| Sizes available: | Single, double, king, super king |
| Type of mattress: | Pocket springs, latex and other natural fibres including wool |
| Firmness: | Medium |
| Delivery: | Free |
In the cushioning pillowtop of this Feather & Black mattress is a layer of natural latex, which is hypoallergenic, provides support and is breathable, helping to avoid overheating at night. The mattress is handmade in Kent, and the three layers of wool inside come from Romney sheep, which are native to Kent. Other natural fibres inside the mattress include insulating mohair, soft cashmere and silk. Underneath, the 3,604 pocket springs (in the double size) respond to your body and provide a base of support. This mattress is also available in a zip and link version.
Again, this is quite a deep mattress which is something to bear in mind. Delivery is in around two weeks, which is longer than some other brands.
Best organic mattress for flexible delivery: Earth Apex Mattress, £1,599.20 from Simba
| Earth Apex Mattress | |
|---|---|
| Care: | Regularly air the mattress, no turn, but rotate every couple of months for the first 6 months, and twice a year thereafter |
| Mattress depth: | 32cm |
| Trial period: | 200 nights |
| Guarantee: | 10 years |
| Sizes available: | Single, double, king, super king |
| Type of mattress: | Sprung base topped with layers of natural materials and springs |
| Firmness: | Medium firm |
| Delivery: | Free VIP delivery |
This offering from Simba's Earth range has an extended sleep trial of 200 nights, the longest of any on our list. On this product, they offer free VIP delivery, which means they contact you to arrange a convenient time for delivery, they will install the new mattress in a room of your choice, and remove and recycle all packaging. For a fee of £50, they can also remove and recycle your old mattress. Unlike with Simba's hybrid and foam products, the focus here is on natural fibres, including cashgora wool (as soft as but more durable than cashmere), smooth yet strong silk, and wool from Hampshire.
Again, the cover is made from plant-derived but partially synthetic fibre viscose, and the springs in the base are encased in polypropolene pockets, so while mostly natural, this mattress does have some manmade elements.
Hampden Mattress, £2,095 from The White Company
| Hampden Mattress | |
|---|---|
| Care: | Spot clean and turn with the seasons |
| Mattress depth: | 27cm |
| Trial period: | According to the website, for hygiene reasons, you can’t return your mattress once you’ve opened the packaging |
| Guarantee: | 10 years |
| Sizes available: | Single, double, king, super king, emperor |
| Type of mattress: | Pocket springs with latex, wool, organic cotton, flax and hemp |
| Firmness: | Medium |
| Delivery: | Free delivery in up to 9 weeks |
This mattress is made to order in the UK by Hypnos with The White Company. It's their top end mattress, crafted with traceable, responsibly produced British wool from Red Tractor-assured farms. They also work with the organisation The Woolkeepers®, which is ‘a quality assurance scheme of which Hypnos is part – is committed to delivering and promoting environmental and social change and ensuring a fair price is paid to the farmer’. It also contains organic cotton, flax and hemp, as well as a layer of natural latex. The surface of the mattress is chemical free.
Due to being handmade to order, the delivery wait could be lengthy, taking up to nine weeks according to the website. No sleep trial is specified, and the mattress cannot be returned due to hygiene reasons. The mattress outer is made from cotton viscose. Viscose is a semi-synthetic fibre, as it is derived from wood pulp, but is then chemically treated in order to make it into a fibre. This does mean that there is an element of this mattress that is not wholly natural.
The Mohair Mattress, £2,630 from Naturalmat (tried & tested)
| Reviewed by: | Jessica Salter, contributing writer |
|---|---|
| Care: | No need to flip |
| Mattress depth: | 21cm |
| Trial period: | All Naturalmat mattresses comes with a 45 day trial period, whereby you can exchange the mattress for a different product |
| Guarantee: | 10 years |
| Sizes available: | Single, double, queen, king, super king and emperor |
| Type of mattress: | Organic latex |
| Firmness: | Very firm |
Whether you like this or not will depend on whether you like a very firm mattress: this is the brand Naturalmat’s firmest mattress, comprising of two chunky layers of coir, which provides the tough stability to the mattress, but also allows it to breath, with a layer of bouncy natural latex in the middle, and wrapped in a needled mohair layer, that helps regulate body temperature. It’s 21cm deep and comes with a ten-year guarantee.
Personally, I like a bit more give than this mattress delivers, but on the brand’s website there are 11 reviews of the mohair mattress, and all of them left five stars. What is a huge bonus is that if you share a bed with someone who has different mattress preferences, you can buy two types with with zip-and-link covers to cater for individual needs.
Only for those looking for a particularly firm mattress.
No. 2 Mattress, £16,780 from Savoir (tried & tested)
| Reviewed by: | Jessica Salter, contributing writer |
|---|---|
| Care: | Flip the mattress after two weeks, then rotate it again two weeks later, before turning it monthly |
| Mattress depth: | 20cm |
| Trial period: | None (returns of unused items accepted within 14 days) |
| Guarantee: | 25 years |
| Sizes available: | Double, king, super king, Savoy king and emperor |
| Type of mattress: | Sprung |
| Firmness: | It comes in three different firmness levels; we tested medium |
This is the Rolls Royce of mattresses: the No 2, which was originally made for The Savoy hotel (and where you can still sleep on one) has hosted guests from Marilyn Monroe to Winston Churchill. Savoir mattresses are all made by hand in their London workshop, using traditional techniques and natural materials including wool, horse tail and cotton to craft the best night’s sleep. Although you won't see it most of the time, we love that it comes in three colours (grey, silver or white), making it stand out from the crowd.
Sleeping on a No 2 is an incredibly luxurious experience: the perfect firmness (they believe that 7.5 turns on the pocket springs ensures this), with no movement if your partner turns over in the night. But of course it’s a huge investment and unlike other companies, there is no trial period. So make sure you visit the showroom – or The Savoy – to thoroughly test this out.
Its extremely high price point puts this mattress out of reach for many. There is a leather label on the mattress, meaning that it is not vegan-friendly.
Owen Mattress, £2,099 from Feather & Black
| Owen Mattress | |
|---|---|
| Care: | Air the mattress regularly, remove dust and fluff every few months using a soft brush, never use a vacuum cleaner, spillages should be absorbed using a dry cloth or paper towels, spot clean with a damp cloth and a very mild solution of soap and water |
| Mattress depth: | 23cm |
| Trial period: | 100 night comfort guarantee |
| Guarantee: | 7 years |
| Sizes available: | Single, small double, double, king, super king, emperor |
| Type of mattress: | Pocket springs with layers of 100% natural fibres |
| Firmness: | Soft or medium |
| Delivery: | Free delivery |
The Owen is crafted in Yorkshire by luxury mattress brand Harrison Spinks, for Feather & Black. Inside is fully traceable British wool, farm-grown hemp, and flax, which is antibacterial and has cooling properties. The double has a whopping 9,000 supportive pocket springs, which are 100% recyclable.
This mattress has a slightly reduced guarantee (7 years), than the 10 years given for the other Feather & Black mattress on this list. Although it claims to be made from 100% natural materials, the surface is a wool-viscose blend, so there is a synthetic element with the viscose.
OTTY Natural Evolve Mattress, £1,149.99 from Otty
| OTTY Natural Evolve Mattress | |
|---|---|
| Care: | Rotate your mattress once a month for the first 12 months and then once every 3 months thereafter, this mattress can also be flipped which is advisable |
| Mattress depth: | 28cm |
| Trial period: | 100 nights |
| Guarantee: | 10 years |
| Sizes available: | Double, king, super king |
| Type of mattress: | Pocket springs with natural wool, cashmere and silk |
| Firmness: | Medium-firm |
| Delivery: | Free delivery to front door, premium delivery to room of choice from £10, extra fee for old mattress collection |
This is the premium mattress in Otty's Natural range. It is made in the UK and durably finished with hand-stitched elements. As well as wool, it includes luxurious silk and cashmere. What's great about this mattress is that it's double-sided - it has a mirror image of all the layers on top and bottom, meaning that it can be flipped as well as rotated.
The cover is made from semi-synthetic viscose.
Is it worth buying an organic mattress?
The benefits of organic mattresses are plentiful.
Good for those with allergies, or if you're concerned about the potential toxins of certain synthetic materials.
Often better for the environment, providing that the materials are grown or harvested in a sustainable manner, and processed without chemicals - we've done our best to select natural mattresses that fall into this category.
If you dislike the synthetic ‘off-gassing’ smell that new memory foam mattresses tend to give off, a natural mattress is a good choice. However, one thing to bear in mind is that some organic mattresses, such as those filled with wool, can have a natural scent of their own, so it's down to preference. We'd recommend heading to a showroom to do a light road-test of any mattresses you're interested in. Lots of companies also offer extensive sleep trials, allowing for flexibility on the purchase.
What is the best organic mattress?
Although there are plenty of choices on the market these days, when it comes to totally natural mattresses that are crafted with consideration from start to finish, Naturalmat is undoubtedly the leader in the field. From their sustainable packaging initiative outlined earlier on in this piece, to their Mattress for Life scheme to refurbish, recycle or donate your mattress at the end of its life, which ensures that your mattress won't be resigned to a landfill. In terms of the manufacturing process, they only use durable natural materials, repurpose fabric offcuts, and make their mattresses to order, which reduces waste.
What is the healthiest type of mattress?
Mattresses made with purely natural materials, that have not been treated chemically, are considered to be the healthiest, both for yourself and the environment. Use of organic materials elimates the risk of toxins and chemicals that can be found in certain synthetic materials, or the artificial smell that a memory foam mattress can give off.
What makes an organic mattress different from a regular mattress?
Focuses on natural materials like organic wool, latex, and cotton, and distinguishes them from synthetic options.
Which certifications should I look for to ensure a mattress is truly organic?
Highlights credible labels like GOTS, GOLS, GREENGUARD Gold, and OEKO-TEX as markers of authenticity and safety.
Are organic mattresses better for people with allergies or asthma?
Explains how natural fibres – especially wool – offer hypoallergenic benefits and resist dust mites and irritants.
Do organic mattresses sleep cooler than conventional mattresses?
Discusses the breathability of materials like wool and latex, and their ability to regulate temperature effectively.
Are organic mattresses worth the extra cost?
Balances the premium investment with long-term benefits – durability, eco-credentials, and better sleep quality.
