Best Wool Mattress 2021

Last Updated: October 15, 2021

Wool is a versatile natural fibre and most likely one of the most well-known natural fibres to be used in mattresses. Despite many misconceptions, there are said to be a range of benefits to using wool, such as being hypoallergenic, a good moisture and temperature regulator, mildew and fungus resistant, a fire retardant, as well as eco-friendly. Wool is also elastic and resilient that makes for a very durable mattress.

If you are looking for a mattress in the medium-firm range but also want something that offers pressure relief and comfort, then a wool mattress could be a good option for you. It is important to note that wool mattresses differ to a large extent in terms of quality and blends, among other things, and there are essential details to look out for and considerations to make when searching for your perfect wool mattress.

This Natural Collection Fleece Wool mattress consists of layers of wool, hemp, and cotton that together provide a temperature-regulated, moisture-controlled, breathable, hypoallergenic environment in which you can sleep.

Wool Mattresses Explained

Wool is made of sheep fur and is often found inside the cover or as a comfort layer in mattresses. As a cover, it is spun into thread and then sewn into the fabric. As a comfort layer, it is packed tightly as loose fur, thereby adding softness to the top layers of the mattress. It’s used rarely in memory foam mattresses and tends to be found in pocket sprung mattresses.

Wool Mattresses Explained

When we think of wool, we may be inclined to think of it being too warm a material on which to sleep. However, this is far from the truth as wool is naturally breathable and has been shown✓ to have excellent heat regulation properties. It is how sheep can tolerate a wide range in temperature!

Wool’s structure makes it robust and resilient to damage, and natural elasticity allows it to stretch comfortably around the body without sagging, providing comfort and support. Research✓ has shown that sleeping on a woollen underlay surface can significantly reduce postural activity and lead to a more restful sleep.

Wool has, however, become a bit of a buzzword in mattress manufacture, and it’s worth noting that not all wool mattresses are created equal. Pure wool on its own tends to compress, so it is often blended to keep its spring and height. These mattresses can use blends of different materials such as cotton or synthetics like polyester or white fibre. Be sure to pay attention to the ‘GSM’ (grams per square metre) and what other materials it’s blended with as a label reading ‘natural wool fillings’ could mean a very minimal amount of pure wool. The combination of materials and the quantities used could significantly affect the quality and durability of the mattress.

Fun Fact! Britain is one of the largest wool producers✓ in the world yielding nearly 22 000 tonnes per year!

Benefits Of A Wool Mattress

Wool as a natural fibre has many qualities and characteristics that make it a potential good material in a mattress.

Benefits of a wool mattress
  • Thermoregulation: If you are someone who battles to sleep due to temperature changes, organic wool mattresses may be a good option for you. Organic wool is naturally breathable (absorbing moisture when the atmosphere is damp and releasing it when the atmosphere is dry) and acts as a thermoregulator (insulating you when it’s cold, and cooling you when it’s hot).
  • Hypoallergenic: For those who have sensitive skin or certain allergies sleeping on mattresses composed of synthetic materials can cause problems. These materials trap moisture and don’t breathe well. Dust mites thrive in dark and damp places and are primary instigators of allergies. It has been well documented✓ that many people suffer sensitivity and allergic reactions to dust mites (more specifically, the droppings of dust mites!). Organic wool is inherently hypoallergenic and antimicrobial, shielding you against dust, dirt, and other irritants or allergens.
  • Mold and mildew resistant: Mold and mildew need a damp environment to survive. Wool has a natural resistance to mildew because the fibres allow moisture to pass through without staying in the wool itself.
  • Fire-resistant: Organic wool is a natural flame retardant as it contains high keratin protein and moisture in every fibre. It is naturally difficult to ignite and doesn’t melt, drip, or release toxic fumes like some synthetic materials. (Note, some companies use mixed-grade wool which requires synthetic chemicals to meet certain mattress standards, which may then result in more flammable material).
  • Eco-friendly: Wool mattresses can be energy-saving, recyclable, biodegradable, and pesticide-free (always read the fine print!).

Are You Really Allergic To Wool?

A global consumer survey published in a literature review✓ showed that 43% of consumers would not purchase a woollen item of clothing as they believed it was itchy or uncomfortable. Similarly, there was at one time widespread belief even within the medical community that wool intolerance was one of the diagnostic criteria✓ for skin allergies. It is now largely recognised that this is not the case.

Are You Really Allergic To Wool

Research is, however, varied on what exactly causes this irritation in so many people. Studies✓ have shown that lanolin, a natural oil found in wool, may be responsible for many peoples’ discomfort. Other research✓ suggests that ‘cutaneous irritation’ from wool relates to the coarseness (fibres with large diameters) and not the contact from the lanolin or other chemicals.

Wool Mattresses: Myths Vs Truths

There are several common misconceptions about wool mattresses, so be sure to do your research before you make up your mind about whether this could be the best mattress for you.

Wool Mattresses: Myths Vs Truths
MYTHSTRUTHS
 ☐ Wool feels itchy
 
✓ Cheaper and coarser variants that are chemically treated can irritate your skin or feel itchy. Chemically processed woollen fibres do not bend easily and therefore feel scratchy on your skin. Choosing an organic wool mattress may avoid this.
 ☐ Wool attracts bugs and allergens
✓ Wool does not hold moisture making it too dry for these allergens to survive. Wool bedding may therefore be the ideal choice for people with allergies/sensitivities.
 ☐ Shearing hurts the sheep
✓ Shearing when done by professionals with special shears, should cause no injury to the animals. Shearing too close to the skin and museling is primarily responsible for animals getting hurt. It is recommended that you do some research in order to make the best-informed decision about which brands use wool sourced from farms practising cruelty-free shearing methods.
 ☐ Wool smells bad
✓ The naturally occurring oil called lanolin gives the wool this smell, however, this chemical is removed as much as possible by thoroughly washing the wool before it is used to manufacture. By the end of the manufacturing process, the odour is removed almost entirely. 
☐ Allergies are aggravated by wool mattresses
✓ Allergy to woollen products is extremely rare and what many people experience is an allergic reaction to the chemicals used for treating wool fibre strands, the lanolin present in them, or often the itchiness caused by coarse wool.

Good to know: Museling is now banned in the UK but still practised in other parts of the world.

Is A Wool Mattress Best For You?

A wool mattress may be a good option for you if you are:

  • Thermosensitive: Organic wool is naturally breathable and acts as a thermoregulator (keeps you warm if you get too cold and cools you if you get too hot).
  • Someone who suffers from household allergies or sensitivities: Wool mattresses are hypoallergenic.
  • A side sleeper or back sleeper: Medium tension wool mattresses are a good, well-rounded choice and provide a good combination of comfort and support.
  • In need of cushioning and pressure relief: Wool mattresses can support the body and distribute weight evenly.
  • A heavier person: Firm wool mattresses may offer the optimal amount of support to prevent sinking and keep the spine aligned.
  • Looking for a long-lasting mattress: Wool fibres are elastic and resilient, and if cared for properly, a wool mattress can last 20 years or more.
  • Wanting an eco-friendly choice: Wool mattresses can be energy-saving, recyclable, biodegradable, and pesticide-free.
  • Concerned about easily flammable materials: Organic wool is a natural flame retardant.
