Natural Mattresses
A natural mattress is filled with materials that come from plants or animals rather than a chemical plant: wool, cotton, cashmere, silk, horsehair and natural latex, usually layered over a pocket spring core. They breathe well and handle temperature and moisture better than foam, and they're built to be turned rather than rolled and boxed.
Natural fillings sit almost entirely at the premium end of the market, which is why most of them appear inside the luxury pocket sprung ranges from British bed makers rather than in a category of their own.
We compare mattresses across UK retailers with prices checked regularly, so you can see which natural options are available and where.

×What is a natural mattress?
A natural mattress uses fillings of natural origin in place of the polyester and polyurethane foams found in most mainstream beds. Wool is the most common, valued for holding warmth in winter while releasing moisture in summer. It is also naturally flame resistant. Cotton adds breathable softness and horsehair gives springy resilience and long life. Cashmere and silk appear at the top of the range for surface feel. Underneath sits a spring unit, usually pocket springs, sometimes hand-nested in calico.
Natural latex belongs to this family too, tapped from rubber trees rather than made from oil, though it behaves differently enough to have its own page. See latex mattresses for that.
Natural is not the same as eco-friendly. Natural describes what the mattress is filled with, while eco-friendly describes how it was made and what can be recovered at the end of its life. In practice those are two different price brackets. See eco-friendly mattresses.
Who natural mattresses suit
- Hot sleepers and anyone who wakes up damp, since wool and cotton move moisture away rather than holding it.
- Buyers who want a mattress to last a decade or more and are willing to turn and rotate it.
- Anyone avoiding synthetic foams, whether for sensitivity or simple preference.
Who might want a different option
- Anyone on a mainstream budget. Natural fillings cost considerably more than foam, and the same money buys a better-specified hybrid.
- People with a wool or animal-fibre allergy, where natural latex or a plant-fibre build is the safer route.
- Anyone who wants a no-turn mattress delivered in a box, since natural builds are usually heavy and double-sided.
What to look for
- Check which fillings are used and how much. A stated weight of wool or a named blend is a real specification; the phrase natural fillings on its own is not.
- Look for hand tufting, which holds the layers together and stops them shifting into lumps. It is the traditional marker of a properly built natural mattress.
- The spring unit sets the support while the fillings set the feel, so check spring type and tension as carefully as the fillings.
- Most natural mattresses are double-sided and need turning several times a year, which matters if lifting is difficult.
How we compare them
We use information from manufacturer and retailer specifications, verified owner reviews and our own catalogue data across more than 800 construction-checked models, with prices checked regularly across our UK retail partners.

What is a natural mattress made of?
Fillings of natural origin over a spring core: wool, cotton, horsehair, cashmere, silk or natural latex, usually layered above pocket springs and held in place with hand tufting. The point of difference from a mainstream mattress is the absence of polyester and polyurethane foam in the comfort layers.
Are natural mattresses better for hot sleepers?
They are among the best options. Wool and cotton absorb and release moisture and let air move through the fillings, so the surface stays drier than foam. A sprung core underneath adds airflow that a solid foam mattress cannot offer.
Why are natural mattresses so expensive?
The materials cost more than foam and are heavier to ship, and much of the construction is done by hand, including the tufting and the nesting of springs in calico. In return a well-made natural mattress is usually double-sided and built to last longer than a foam equivalent.
Is a natural mattress the same as an organic one?
No. Natural describes the origin of the materials; organic describes how they were farmed and requires certification, such as GOTS for cotton and wool. A natural mattress can contain non-organic wool, and the label should tell you which it is.
Where do I find natural mattresses if the choice here is small?
Most natural fillings appear in the premium sprung ranges from British bed makers, so our pocket spring range is where to look, particularly at the higher-priced end. Latex mattresses are the other natural route.
