A heavenly combination of nature’s finest materials - the most luxurious mattress in our Natural Fibre collection

The Cashmere begins with a supportive, breathable core of organic coconut fibres, which we surround with two thick layers of comfy blended natural latex. We then add a layer of gorgeous cashmere and to finish, a topping of our locally sourced organic wool. Our softest Natural Fibre mattress, but still on the firmer, denser end of our full range.

  • 1. Cashmere

    From the soft fleece of cashmere or pashmina goats, a luxurious layer of insulation and breathability.

  • 2. Natural Latex

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

  • 3. Organic Coir

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

  • 4. Organic Wool

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

We pull out all the stops for the Cashmere. We combine generous helpings of our signature natural fibres with cashmere, one of nature’s most prized materials, renowned for its superior insulation and breathability. As with all of our mattresses, the Cashmere provides exceptional comfort, free from any harmful chemicals and other nasties.

When it comes to our Natural Fibre range, it’s all about the layering. The order in which we stack our carefully sourced organic and natural fibres, and the thickness of those layers, dictates the firmness and density of the mattress. In the case of the Cashmere we double up on the wondrous material that is natural latex (see below to learn more). More latex equals a softer feel when compared to the two other Natural Fibre mattresses in our range. For more information on mattress firmness, check out our guide here.

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 to the public. An overwhelming majority of manufacturers achieve this certification by treating their products with chemical fire retardants. ​This never sat right with us, and we worked to develop a cover fabric 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.

    Lovely mattress

    I feel very supported when sleeping on this mattress. And love the fact that it can be refilled when needed.

    This is, without question, the most comfortable mattress which we have ever owned. Worth every penny. Cannot recommend too highly.

    Easy ordering on website and quick dispatch.

    Good quality product though a little expensive. Would buy one for every bed in the house but the cost would be prohibitive :-(.
