Are Wool Mattresses Any Good?

Key Takeaways

• Wool mattresses offer natural temperature regulation, moisture control, and hypoallergenic benefits.
• They’re eco-friendly, durable, and free from many synthetic chemicals found in conventional beds.
• Wool mattresses work for everyone, but especially for allergy sufferers, hot sleepers, and eco-conscious buyers seeking organic materials.

If you’re shopping for a new mattress, you’ve probably seen a lot of options for conventional beds in a box—hybrids or all-foam mattresses made with some type of polyurethane foam. Wool may have popped up here or there as a premium natural offering—and it might have made you wonder whether wool mattresses are actually any good. Well, yes! As a fiber, wool is wonderfully suited to better sleep. It regulates temperature, wicks moisture, and deters allergens and dust mites, contributing to a cleaner, more comfortable sleep space. It’s incredibly durable in addition to being biodegradable, renewable, and free of chemical additives, so it’s a top choice for eco-minded shoppers. But the truth is, just about every type of sleeper benefits from sleeping on a well-made wool mattress. Whether you're dealing with night sweats, allergies, or you just simply want a healthier place to rest your head, wool could be the mattress material you didn’t even know you needed.

What is a Wool Mattress?

A wool mattress is just what you’re imagining—a mattress made with wool. But if you’re trying to picture your favorite wool sweater in mattress form, think again. A wool mattress, like those here at Woolroom, is comparable to a traditional hybrid in its basic construction. But instead of using synthetic fills, chemical flame retardants, and the kinds of petroleum-based foams that lead to off-gassing, our natural wool mattresses are made with traceable British wool and pocketed coil systems. That means no petrochemicals, no glues, no adhesives, and no chemical flame retardants. Instead, we rely on the innate properties of wool to keep the mattress clean and dry and resistant to fire, along with hand tufting to ensure every layer stays perfectly in place.

Benefits of Wool Mattresses

Wool mattresses tend to outperform conventional beds because of the wool itself. It really is a wondrous fiber, especially when it comes to sleep.

• Natural temperature regulation. Individual wool fibers are shaped like tiny little springs, and it’s this crimped shape that makes it so adept at regulating temperature. When multiple wool fibers overlap, their curled design creates countless little air pockets that can hold onto heat for insulation and allow air to circulate. That ability to both insulate and breathe is what makes wool such an excellent bedding material all year long.

• Wicks moisture to keep you dry. Whether you consider yourself a hot sleeper or not, your body temperature fluctuates at night as part of the thermoregulation process. Wool fibers can absorb up to 30% of their body weight in moisture without becoming damp, heavy, or otherwise unpleasant. In a wool mattress, the breathable wool layer pulls away sweat and humidity from your skin before releasing it into the air. It’s a passive but efficient system that prevents overheating and the kind of clamminess or outright sweating that interferes with a good night’s sleep.

• Hypoallergenic and resistant to dust mites. Between its breathability and moisture wicking prowess, wool isn’t hospitable to common allergens and irritants. Microscopic contaminants like dust mites, dander, mold, mildew, and bacteria thrive in dark, moist environments. That’s exactly what you get with materials like polyurethane foam, synthetic fabrics, and even down—but not with wool. If nighttime allergies are a constant bother for you, upgrading to wool bedding could be the simplest and most effective solution.

• Resists odors. A conventional mattress that traps your body heat and sweat for hours on end night after night can begin to develop an odor. That’s not a concern with wool—the fiber is naturally resistant to odors because it stays so much drier.

• Natural flame resistance. Mattresses made with synthetic materials are required to use chemical flame retardants, but wool meets flammability standards all by itself—no chemicals needed. That makes wool mattresses ideal for people who are consciously reducing their exposure to chemicals in the home.

• Eco-friendly and biodegradable. Wool is renewable and biodegradable, and at Woolroom, we ensure it’s also sustainable and ethical. We partner with farms that are committed to the five freedoms mandated in the UK Animal Welfare Act of 2006, and our Wool ID® program means all of our wool can be traced back to the source—the sheep! 

• Durable and long lasting. Durability is a hallmark of wool, which is why wool fibers can be recycled repeatedly without impacting tensile strength. Cared for properly, a high-quality wool mattress can last for well over a decade.

Drawbacks of Wool Mattresses

For all their benefits, there can be downsides to wool mattresses. Here’s what to keep in mind

• Higher upfront cost. Wool mattresses can be more expensive than basic foam or innerspring options, but the price is a reflection of higher quality materials, ethical sourcing, and craftsmanship. It’s a bigger upfront investment, but keep in mind that wool mattresses will outlast their synthetic counterparts, saving you money in the long run. Don’t forget that cheap mattresses are cheap in more ways than one!

• More weight. Natural materials, like wool and cotton, can be a little heavier than synthetic foams, so wool mattresses can be harder to rotate or move.

• Initial “wool” scent. Wool mattresses don’t offgas volatile organic compounds (VOCs) like synthetic mattresses, but they can have an initial faint scent. It’s not chemical or even unpleasant and it fades in the first week or so, but it’s worth knowing upfront.

Who Should Choose a Wool Mattress?

A wool mattress is a great choice for anyone interested in better sleep. According to research conducted by Leeds University for Woolroom, wool bedding actually boosts regenerative sleep by 25%! Still, certain people may benefit even more from a wool mattress. Allergy sufferers, hot sleepers, those who suffer from night sweats, eco-minded shoppers, and people who are interested in a non-toxic, all-natural mattress will find Woolroom’s natural wool mattresses meet their needs—and then some.

What Makes Woolroom Mattresses Different?

Wool might be a dreamy fiber for sleep, but that doesn’t mean all wool mattresses are created equal. Quality varies widely, and before you invest in a bed sight unseen, it’s really important to familiarize yourself with what makes one wool mattress better than another. At Woolroom, our commitment to quality, sustainability, health, and ethical sourcing sets our wool mattresses well apart. 

Our partner farms share our view that the best wool comes from the healthiest, happiest animals, and our Wool ID® Program is a testament to our transparency at every point in the supply chain. It’s a guarantee that all of the wool in our mattresses (and all of our wool bedding products) is fully traceable all the way back to the farm and the sheep it came from. All wool is processed in our own facilities, where it’s carefully checked, sorted, graded, and classified to our very strict quality standards. Then it goes to our skilled artisans. The whole process is based on 150 years of experience in crafting natural wool bedding and mattresses.

Woolroom’s wool mattresses are just built with care—they’re also tested for safety and performance. Independent testing at the Bio Composites center at Bangor University confirms our mattresses are free of harmful VOCs, and all of our bedding is certified by OEKO-TEX Standard 100. Our farms and production facilities have also earned GOTS (Global Organic Textile Standard) certification. In other words, our mattresses and all of our wool bedding are a thoughtful combination of craftsmanship, integrity, and nature’s best fiber for sleep.

The Bottom Line: Is a Wool Mattress Worth It?

After all, natural temperature regulation, moisture control, hypoallergenic properties, and a chemical-free construction add up to pretty ideal sleep conditions. Woolroom takes these benefits even further with our commitment to ethical and traceable sourcing and long list of certifications. It means our mattresses aren’t just better for you and your family—they’re better for the planet.
