Our most luxurious pocket sprung mattress blends nature’s most decadent materials for the ultimate in comfort.

No expense has been spared to bring together this harmonious orchestra of the most prized natural mattress making materials - including cashmere and needled horsehair. All perfectly balanced with one aim in mind: a better night’s sleep, naturally.

  • 1. Natural Latex

    From the sap of the Hevea rubber tree. A springy and supportive natural alternative to synthetic foams.

  • 2. Organic Coir

    Organic coconut husk fibres, bound with rubber. Breathable, supportive, durable, and an infinitely renewable material.

  • 3. Pocket Springs

    Hand nested in individual cotton pockets and available in three tensions - firm, medium and soft.

  • 4. Organic Wool

    Sourced from local organic farms. Traps heat when you need it and disperses it when you don’t.

  • 5. Organic Cotton

    Naturally fire retardant mattress covers made with a signature blend of organic cotton and wool.

The Sumptuous - where the world’s most luxurious natural fibres and our cleverest design ideas meet. Take a look back into the history of luxury mattress making, and you’ll find fibres such as horsehair and cashmere were once prevalent. They’ve always been prized for their natural spring, breathability and durability, but over the decades have been superseded by cheaper synthetic materials.

We combine these layers of cashmere, and horsehair needled with coconut fibres, with our signature natural latex and organic locally sourced wool. The layers unite to provide superior comfort and breathability, aiding your temperature control and allowing you a more settled night’s sleep whatever the weather. For extra support and long-term rigidity on the most wear-sensitive part of the mattress - its edges - we encase the Sumptuous’ spring unit with a hessian wrapped layer of organic coir.

A Mattress For Life

Over 5 million mattresses end up in landfill every year in the UK alone, a truly terrifying statistic.

Our Mattress for Life Initiative™ ensures this should never happen to our mattresses. When your Naturalmat nears the end of its lifespan (around 10 years from now!), we offer three options to ensure absolutely nothing goes to landfill:

Refurbish | Recycle | Donate

Clever Covers

In the UK there are strict fire safety standards that mattresses must pass before they can be sold. The majority of manufacturers achieve this certification by treating their products with chemical fire retardants, but ​this never sat right with us. So we developed a unique covering fabric, woven with a blend of organic cotton and wool, that met the safety requirements without the need for any chemicals whatsoever.

We are also the only mattress manufacturer to add a hypoallergenic finishing process to our covers. We treat them with an Oeko-Tex certified geraniol treatment to guarantee protection from dust mites and bed bugs - perfect for allergy sufferers, whose conditions are often triggered by these unwelcome bedfellows.

Handmade in Devon

At Naturalmat, we believe that people, not machines, make a superior, long-lasting product. Our team of craftspeople ensure every stitch, every fibre, every tufting button and every cover is painstakingly created, teased and checked. That’s why we proudly stamp ‘Made by hand in Devon’ on all of our mattresses.

Sustainable Packaging

We’ve never liked the idea of delivering our beds and mattresses in reams of bulky, plastic packaging - so we challenged ourselves to get rid of it altogether.

In 2021 we introduced these sturdy, waterproof reusable delivery bags, which were specially made for us in the UK. We now deliver almost all of our beds and mattresses in these reusable bags, saving over 5,000kg of single-use plastic since their introduction.

    Just perfect

    Visited the Exeter showroom and was greeted by Ishwari, who was excellent and took the time to go over our requirements to make sure we got exactly what we needed. New mattress arrived on time as promised, felt a little firmer than the showroom one initially, but after around 4 weeks has softened slightly and is now just right! Bit more expensive than others, but you definitely get what you pay for with both service and product. Go and see them, you won’t regret it!

    a great combination of non toxic and very comfortable

    I spent a good amount of time at Naturalmat shop trying out beds and was torn between soft and medium. We ended up going for soft Sumptuous and it has been lovely. I realised I'd spent most of my life sleeping on slightly too firm mattresses. As a side sleeper the combination of some softness while still providing good support is ideal.

    Fantastic mattress and service

    I don't think I've experienced better service than in the Knutsford showroom. The space and set up is brilliant and so well thought out. Louise was friendly and helpful and achieved the perfect balance of providing information and leaving us to try the mattresses out and browse around the shop. There is no aggressive hard sell here like there is in so many other places. I only wish every shopping trip for big items could be like this! And that other companies were so people and planet conscious.

    We both love the mattress, it is very comfortable, we have great nights sleep on it and it is warm too. I'm very happy we bought it and wouldn't hesitate to buy another one.

    Great Mattress and Great Service

    From the moment we stepped foot in the Chiswick Showroom we experienced such wonderful service. Explaining the types of mattresses and different materials, to spending a good amount of time testing out the beds which is no mean feat with two young children. It was important to me to buy an organic mattress using natural materials. When we ordered the mattress the production team were so accommodating when we needed to delay delivery, and on the day the bed arrived the delivery guys were so friendly and helpful. The bed itself is everything we hoped it to be and the quality and craftsmanship is evident. I loved our old mattress, as a side sleeper it was so supportive, but it was long overdue replacing (20 years) and we are so happy we chose Naturalmat.

    Fabulous mattress!

    Initially we were shopping for any mattress that would fit our emperor size bed, which was real hard work & pretty stressful at times. I hadn’t heard of Naturalmat previously so when I found them online we soon popped into their Topsham showroom to discuss our options! The showroom staff were amazing, listened to every question we had and offered their best advice to our conundrums. We decided to take some time to think it over as it is a large purchase but we’re so glad we did! I’ve never slept so well. The delivery was seamless, delivery staff utterly amazing also & took our old mattress away to be recycled and used elsewhere. We are definitely now a lifetime customer.
