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.

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 They’ve always been prized for their natural spring, breathability and durability, but over the decades have been superseded by cheaper synthetic materials.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. An overwhelming 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 covering fabric woven exclusively from 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 pr​ocess to our covers. We treat them with natural extracts 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 3,400kg of single use plastic since their introduction.

    Excellent!

    I am so pleased with my purchase. The service I received at the showroom near Exeter was exemplary in ensuring that I was able to test various mattresses so that I was able to choose the one which suited me best. Not rushed and no hard sell! I was kept informed of progress, which was very helpful, and on the day that the mattress was delivered, the old one was also taken away for recycling, etc - so helpful.

    The mattress is extremely comfortable and suits me very well. I would unhesitatingly recommend this company to anyone interested in purchasing a new mattress.
