Are wool mattresses actually wool?

Wool mattresses are rarely made entirely of wool. 🐑

Typically, they are pocket spring mattresses with a wool layer on top.

A pocket spring mattress has spiral-shaped springs wrapped in fabric pockets. Each spring moves independently and responds exactly where pressure is applied. This provides precise body adaption and a pressure-relieving effect.
layers of wool mattress
The inside of a wool mattress usually features pocket springs.

For example, the Harrison Spinks Saltaire 10750 Pocket Mattress has a wool layer followed by a layer of cashmere, mohair silk, and pocket springs.

We dive into the different benefits of wool mattresses and their composition further down.


What are the benefits of a wool mattress?

Wool includes all kinds of features that can improve a mattress.

Let’s get into the different benefits.

Benefits of wool mattress

Breathable and moisture-wicking

Wool mattresses are constructed using natural fibres from sheep’s wool.

Wool fibres are crimped, and when woven or packed together, they form a dense, layered structure with small air pockets that allow for circulation. 🌬️

This breathability ensures that your sheep wool mattress maintains a comfortable sleeping temperature, preventing heat and moisture build-up.

Additionally, wool fibres can absorb a lot of moisture, drawing it away from the body and releasing it into the air.

This moisture-wicking property helps to keep you dry and comfortable throughout the night.


As we’ve just discussed, wool fibres have air pockets, encouraging breathability.

However, these air pockets also trap body heat, forming a natural insulating layer that keeps warmth close to the skin. 🌡️

wool layer temperature

Unlike synthetic materials, wool has a natural ability to regulate temperature.

This means that while it provides warmth in colder conditions, it doesn't overheat the sleeper because of its breathability and moisture-wicking capabilities.

Supports British farming

Choosing an organic wool mattress often means supporting local agriculture, particularly if the wool is sourced from British farms. 🇬🇧

British wool is renowned for its quality and durability.

By selecting a British wool mattress, like the Hypnos Wool Origins 6 Mattress, you're contributing to the local economy and helping sustain traditional farming practices.


Free from toxic chemicals

Most natural wool mattresses are free from harsh chemicals.

Chemical treatments on mattresses, such as fire retardants, can off-gas harmful volatile organic compounds that accumulate in the body and cause allergic reactions.

fire retardant mattress

Wool is made from keratin protein, one of the most flame-resistant natural fibres, so it doesn’t require additional fire-resistant treatments.

However, wool mattresses are rarely made entirely from wool, so these mattresses often need an additional treatment to cover all the other materials.

For example, Millbrook’s Wool Luxury 4000 Pocket Mattress has an M-Pure cover treatment for additional fire resistance.

The M-Pure cover is a 100% natural, plant-based treatment without harsh chemicals that protects the mattress from fire.



Wool fibres are known to be coarse and resilient.

They can be bent and twisted thousands of times without breaking.

woman sat on wool mattress
Wool mattresses keep their shape, even when you sit on the edge of the bed.

This natural elasticity allows wool mattresses to maintain their shape and support over time.

With proper care, a luxury wool mattress can last for decades, outperforming many synthetic alternatives in terms of longevity.

Who are wool mattresses suitable for?

Wool mattresses are comfortable, sustainable and suitable for a variety of sleepers.

Here’s a detailed look at who wool mattresses are best suited to. 👇

Hot sleepers

Wool is known for its natural thermoregulating properties, which we explained above.

This makes wool mattresses perfect for hot sleepers needing breathable and moisture-wicking mattresses.

Wool mattresses often include other cooling technology as well, like a breathable cotton cover or foam layer. 🧊

simba hybrid pro composition
The Simba Hybrid Pro combines wool with a cooling layer of Simbatex foam.

For example, the Simba Hybrid Pro mattress includes a layer of Simbatex foam underneath the wool layer.

Simbatex foam has an open-cell structure that allows air to flow within the mattress.

It’s also infused with graphite, a natural heat conductor that draws heat away from your body.


Allergy sufferers

Wool is naturally hypoallergenic and resistant to dust mites, mould, and mildew, which are common allergens that can disrupt sleep. 🦠

This is down to wool’s moisture-wicking capabilities that keep your mattress dry, creating a less hospitable environment for bacteria.

Moreover, wool’s natural lanolin content is also known to repel dust mites with its distinct odour.

This keeps the dust mites at bay and your allergies under control.

Eco-conscious people

Wool mattresses are an excellent choice for individuals concerned about the environmental impact of their purchases.

Wool is a renewable resource, sheared from sheep annually without harming them.

It is biodegradable, meaning it will decompose naturally at the end of its life cycle.

Additionally, wool production has a lower carbon footprint than synthetic materials, making it a sustainable choice for environmentally conscious consumers.

Front and back sleepers

Wool mattresses tend to be firmer due to the natural resilience and density of wool fibres.

This firmness typically provides excellent support for front and back sleepers and helps maintain spinal alignment.

Stomach sleeper on wool mattress
A firm wool mattress is a great choice for front and back sleepers.

For stomach sleepers, a firm mattress prevents your hips and abdomen from sinking too deeply and prevents lower back pain as a result.

For back sleepers, the even support helps maintain the spine's natural curve, preventing the back from arching and causing you discomfort.

Who are wool mattresses not suitable for?

While wool mattresses offer a range of benefits for many sleepers, another mattress material may be better suited for others.

Here's a closer look at who might not find wool mattresses suitable.

Side sleepers

Wool mattresses are typically on the firmer side, as we discussed above.

Side sleepers, however, should opt for a softer mattress that contours the body’s curves and supports your hips and shoulders.

A firm wool mattress might be uncomfortable for side sleepers and could potentially disrupt spinal alignment.

Side sleeper on soft mattress
Side sleepers may find a softer mattress is more comfortable.

The Hypnos Wool Origins 6 Mattress is available in two firmness levels: medium and firm. 🥳

If you’re a side sleeper looking for a wool mattress, we recommend trying the medium level to see if it works for you.


Older people

Wool mattresses tend to be constructed from several layers of wool, pocket springs and other materials.

While this improves their comfort and support, it also makes them quite heavy.

This makes it difficult to move or rotate a wool mattress, especially for older individuals or those with limited strength, posing a challenge for routine cleaning or maintenance. 🫧

turning handles on wool mattress
Turning handles are a must-have for heavy mattresses that can’t be flipped.

Fortunately, many wool mattresses, such as the Harrison Spinks Saltaire 10750 Pocket Mattress, come with turning handles to rotate the mattress instead of flipping it over.


How much do wool mattresses cost?

Our recommended wool mattresses come at multiple different price points.

Harrison Spinks and Hypnos typically offer wool mattresses upwards of £2000, while Sleepeezee has a wool mattress for under £1000.


Simba and Millbrook sit in the middle, around the £1000 to £1500 mark.

However, all these brands offer excellent discount codes and deals around the big holiday events, like Black Friday, Cyber Monday and Boxing Day.

We will update you on the latest deals for our recommended wool mattresses on this page.

Grab yourself a bargain on a wool mattress in the holiday sales.

It’s also worth looking at the trial period and guarantee of your wool mattress before you click ‘buy.’

For example, the Harrison Spinks Saltaire Mattress and Millbrook Wool Luxury 4000 Pocket Mattress only come with a five-year guarantee and a 60-night trial period on Mattress Online.

In comparison, Simba offers an impressive 200-night sleep trial and a ten-year guarantee to thoroughly test your mattress and ensure you get your money’s worth over the next decade.


Are wool mattresses worth it?

A wool mattress is a luxury and sustainable product that comes with a wide range of benefits.

They are firm, temperature-regulating and great for allergy sufferers.

Wool mattresses are also durable and often include other innovative technology, like pocket springs or cooling foam.

However, they tend to be on the more expensive side of the mattress market, especially if you opt for the more luxurious brands like Harrison Spinks and Millbrook.

Wool mattresses are worth the cost if you need an innovative, eco-friendly mattress that will provide support, temperature regulation and allergy relief for years to come.

When it comes to the best wool mattress (UK), we recommend the Simba Hybrid Pro for its hotel-quality and luxurious wool layer.
