The most popular mattress in our Natural Fibre range. Favoured by our customers who prefer a firmer, denser level of comfort.

The Lambswool is handcrafted with layers of natural latex and organic wool, around a thick core of organic coconut fibres, known as coir. This central layer helps provide a denser than average feel, perfect for those looking for a firmer mattress. A firm fan favourite, you could say.

  • 1. Organic Wool

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

  • 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.

Our range of Natural Fibre mattresses gain their levels of comfort and support through the layering of our carefully selected natural materials. Organic coconut fibres, known as coir, provide stability. Natural latex, tapped from the Hevea rubber tree, brings the bounce. This duo are complimented by a layer of beautiful locally sourced organic wool, that delivers exceptional temperature control.

In the Lambswool - our most popular Natural Fibre mattress - the firmer, denser feel comes from its core. The central layer of the mattress is made up of a thick sheet of organic coir, with thousands of coiled coconut fibres imparting a firmer feel. We sandwich this coir with two slimmer layers of natural latex to produce a mattress second only to our Mohair on the firm end of our mattress tension guide. Firmer and denser than most, but still blissfully breathable, supportive and comfortable.

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.

    Comfortable and breathable - well worth the money

    We found it slightly too firm at first but, as promised, it has softened/adjusted in use and is now extremely comfortable. In particular, the breathability and temperature regulation is a huge improvement on our previous (memory foam) mattress - I used to regularly get far too hot, but no longer - and we’re now both sleeping very well. Very happy indeed with the mattress.

    The most comfortable mattress EVER

    I’m so happy about this mattress. I’ve never had mattress this comfortable with nothing to complain about. The sleep zone at the shop was very helpful for me to physically try out and decide on the mattress that fits my needs.
