A wool mattress uses layers of wool, in place of foam, as the cushioning between you and the springs. Wool is the most common natural filling in British mattresses, and it behaves very differently from memory foam. This guide covers how it feels, what it does well, where it falls short and what to check before you buy one.
Quick answer: Yes, wool mattresses are a good choice for many sleepers, especially if you sleep warm or dislike the sinking feel of memory foam. Wool lets heat and moisture escape and gives a cushioned, supportive surface. The trade-offs are a firmer feel, a higher price and fillings that settle, so the mattress needs rotating. How good a wool mattress is depends on how much wool it contains and what sits underneath it.
How we put this guide together
We make and sell mattresses, including one wool mattress, so treat our product pick as exactly that. The guidance on wool applies to any brand, and where the evidence is thin we say so.
What is a wool mattress?
In almost every case it is a pocket sprung mattress with wool comfort layers. The springs do the supporting, and the wool sits above them to cushion the body and manage temperature.
"Wool mattress" is not a regulated term. It can describe a mattress with deep layers of pure wool, or one with a thin wool blend quilted into the cover over foam. Both can be sold under the same name, which is why the questions further down matter.
Wool mattresses are one type of natural mattress. Our natural mattress guide covers the others, including cotton and natural latex.
What wool does well
It handles moisture
Wool fibres absorb moisture vapour and release it again as the air around them dries. In a bed, that means sweat is drawn away from the surface instead of sitting against your skin. This is the main reason wool feels less clammy than dense foam.
It keeps temperature steadier
The natural crimp in wool fibres traps air, which insulates in winter. Because moisture can escape, it does not build up heat in the way a closed foam layer can in summer. Wool does not feel cold to the touch. It is better described as temperature regulating than cooling.
If overheating is your main problem, see our guides to the best cooling mattresses and the best mattress for night sweats.
It resists fire without melting
According to the International Wool Textile Organisation, wool is difficult to ignite (570 to 600°C) and does not melt, unlike polyester and nylon. That is one reason mattress makers place it close to the sleeping surface.
It is springy and resilient
Wool fibres bend and recover many times before they break, so a wool layer keeps some loft over time. It gives a cushioned surface that pushes back gently, so you lie on the mattress instead of sinking into it.
Does wool help you sleep better?
The honest answer is that the evidence is promising but limited. A 2024 systematic review in the Journal of Sleep Research looked at nine studies of sleepwear and bedding fibres. It found that wool sleepwear showed benefits for falling asleep in adults in cool conditions and in older adults in warm conditions.
Two cautions. Those studies were about sleepwear and bedding, not mattresses, and the review was funded by a wool industry body. It is reasonable to expect wool to help with comfort and temperature. It is not proven that a wool mattress will improve your sleep.
Wool mattress pros and cons
| Pros | Cons |
|---|---|
| Lets heat and moisture escape | Firmer surface feel than memory foam |
| Supportive, with no sinking feeling | Less close contouring for side sleepers who like a soft hug |
| Comfortable in both summer and winter | Fillings settle, so it needs regular rotating |
| A natural, renewable fibre in place of foam | Costs more than a comparable foam mattress |
| Does not melt and is hard to ignite | Not suitable if you are sensitive to wool |
Wool vs memory foam
| Wool | Memory foam | |
|---|---|---|
| Feel | Cushioned and buoyant | Slow, close moulding |
| Heat | Releases heat and moisture | Can hold heat. Open-cell and gel foams are cooler |
| Pressure relief | Good | Very good |
| Moving around | Easy to turn over | Can feel like you are held in place |
| Best for | Warm sleepers, back sleepers, people who dislike sinking | Side sleepers and those who want deep contouring |
Neither is the better material for everyone. If you want the contouring of foam with the airflow of springs, a hybrid mattress sits between the two.
What to check before you buy a wool mattress
- How much wool, and where. Ask whether the wool forms the comfort layers or is only quilted into the cover. Some makers give a weight in grams per square metre (gsm), which lets you compare.
- Pure wool or a blend. Wool is often blended with polyester or cotton. A blend is not a problem, but you should know what you are paying for.
- Where the wool comes from. British wool is coarse and springy, which suits mattress fillings well.
- What is underneath. Pocket springs give better support and less partner disturbance than open coil. Check whether there is foam below the wool.
- Tufted or tuft-free. Traditional wool mattresses are tufted with buttons to hold the fillings. Some people feel them through the cover. Tuft-free designs avoid this.
- Turn or no-turn. Double-sided wool mattresses need flipping as well as rotating, and they are heavy. No-turn models only need rotating.
- Firmness. Wool mattresses tend to feel firmer than their rating suggests if you are used to foam. Our mattress firmness guide explains the scale.
- A home trial. Wool feels different, so the chance to sleep on it for weeks matters more than usual.

Looking after a wool mattress
- Expect some settlement. Wool beds down in the first few weeks, which can leave slight impressions where you lie. This is normal for natural fillings. Our guide to mattress settlement explains what to expect.
- Rotate it. Turn the mattress head to foot regularly, more often in the first few months.
- Do not wash it. A wool mattress cannot be washed or soaked. Blot spills quickly and spot clean the cover only. See how to clean a mattress.
- Use a protector. A breathable mattress protector keeps spills and skin flakes out without blocking airflow.
- Air the bed. Pull the duvet back for a while each morning so moisture can escape.

Wool mattress FAQs
Are wool mattresses any good?
Yes, for the right sleeper. They are supportive, let heat and moisture escape and avoid the sinking feel of memory foam. They suit warm sleepers and back sleepers particularly well. They are less suited to people who want a very soft, contouring surface.
Is a wool mattress cooling?
Wool is temperature regulating, not cold to the touch. It moves moisture away from the body and lets heat escape, which stops the bed feeling clammy. If you want a surface that actively feels cool, look at cooling foams and cold-touch covers instead.
Do wool mattresses attract moths?
Clothes moth larvae can feed on wool, so it is possible, but it is uncommon in a mattress that is in regular use. The wool is enclosed inside the cover, and moths prefer dark, undisturbed places. Keep the bedroom clean, vacuum under the bed and air the mattress. If you are concerned, ask the maker whether the wool is treated.
Can you wash a wool mattress?
No. Soaking a wool mattress can damage the fillings and it will not dry properly. Blot spills straight away, spot clean the cover and use a washable protector to keep the mattress clean.
Are wool mattresses good for allergies?
They can help, because a drier sleeping surface is less welcoming to dust mites. No mattress filling removes allergens on its own, so a washable protector and regular cleaning still matter. A small number of people are sensitive to wool itself. If you have a diagnosed allergy, speak to your GP before you buy.
Which wool mattress is best in the UK?
It depends on your budget and how firm you like your bed. Look for wool in the comfort layers, pocket springs underneath and a home trial. Our Natural Lux won Best Mattress in the Expert Reviews Sleep Awards 2026.
