All About Wool: How to Choose the Best Wool Mattress Topper

Are wool mattress toppers comfortable?

Wool is made from the fleece of sheep and other animals. There are many wool types and they all look and feel different. Cashmere is one of the softest and most expensive types of wool. Mohair is used for carpets and winter items. The wool used in mattress toppers is comfortable as they’re typically sourced from alpaca and soft types of wool. Sometimes, different wool types are combined in one mattress topper to give you the most comfort.

Do wool mattress toppers keep you cool?

Whatever the season, wool mattress toppers feel pleasant to touch because it regulates temperature. It’s well-known for its insulating abilities but it also keeps you cool, too. It regulates temperature in the summer by wicking away moisture from the body. The natural fibers in wool are breathable so you won’t feel that stickiness that can come from mattress toppers made from synthetic materials.

What are the advantages/benefits of a wool mattress topper

Temperature Regulating

Wool is known to be highly insulating. Fleece protects sheep from the harshest conditions, so it’s no wonder wool warms you up in winter. During humid summers, it will keep you cool because it’s naturally breathable and moisture-wicking. You’ll get good use out of your wool topper throughout the year, making it a good and cost-effective purchase.


Temperature is only one factor in getting a good night’s sleep. Comfort is arguably a more important one to consider. Wool definitely ticks the comfort box because, with the right type of wool, you’ll get a soft and plush mattress topper that will coax you gently into a deep sleep.

Diversity of Options

There’s a wool topper for all types of sleepers and budgets. Merino and cashmere are the high end versions for the sleeper looking for a bit of luxury. British and alpaca wool are trusty and durable. Lambswool is one of the softest, sheared from the first fleece of a lamb. There are also mohair and angora options, as well as handcrafted wool mattress toppers. Some types are branded as eco-friendly wool. Wool mattress toppers often come with a cover, usually made of a breathable fabric like cotton.


Wool mattress toppers will not trigger your allergies if they’re not treated with lanolin, a common allergen, and have a fine micron count. The risk of allergy is averted because the wool is covered with another type of fabric, thus protecting the person from coming in contact with the fibers.

Wool is mold and mildew-resistant. It also inhibits the growth of dust mites. Organic wool is free from harmful chemicals that irritate some people. If you have respiratory issues or are sensitive to certain chemicals, wool is a great mattress topper option.


A wool topper is as good as any kind of mattress topper when it comes to comfort. It’s great for refreshing a saggy or lumpy mattress. A good wool mattress topper will be thick enough to offer ample cushioning. Go for one that strikes a balance between softness and support.

Motion and Noise Control

If you’re often disturbed by the rustling and tossing of your sleeping partner, a wool mattress topper presents a solution. It absorbs motion from the other side of the bed, so you won’t feel it as you sleep. What’s even better is that wool will not make noise as you move through the night.


Looking for a mattress topper that will last? Try wool. Despite their softness, they’re also extremely durable and low maintenance. It will retain its cushioning for years. If you spill or stain a wool mattress topper, you can wipe off the blotches since it’s moisture-resistant.


Wool is eco-friendly because it’s a renewable and biodegradable textile. A wool mattress topper will be made from natural materials. Sheep, lambs, and goats can grow back their wool. The harvesting is sustainable and non-polluting.

A lot of companies are going cruelty-free, which gives a consumer peace of mind that no animals were treated unethically in manufacturing the wool.

Organic wool is made without toxic chemicals such as flame retardants and pesticides.

How to choose the best wool mattress topper

Material and Construction

Firstly, consider the type of wool and threads used in the mattress topper. The casing is as important as the padding because the fabric comes in contact with your skin as you sleep. Natural and breathable cloths are better. A thread count makes it easy to determine how smooth the fabric will be. Anti-slip straps are also an excellent addition.

Thickness and Comfort

Breathability is paramount in a good mattress topper. It should be able to regulate temperature in hot and cold conditions. Comfort is another criterion. This depends on the material and thickness of the mattress topper. If you need support, go for a loft of at least 2 inches. Padding will soothe any aches and pains and promote restful slumber. A comfortable but firm cushion will support the head and spine so you don’t wake up feeling sore.

Maintenance and Durability

A good mattress topper will not flatten over time and is constructed well to prevent fraying. The materials used should be strong enough to withstand the weight of the sleeper. It shouldn’t be treated with harmful chemicals. A machine-washable mattress topper is practical. However, some toppers will require dry cleaning and spot cleaning only.

What’s the best way to use/care for a wool mattress topper?

To maintain your wool mattress topper’s quality, follow the care instructions recommended by the manufacturer. Some wool mattress toppers are strictly spot-clean-only while others can be machine washed. Manufacturers may also advise you to dry clean the topper occasionally. You can air out the wool and expose it to sunlight to let the fibers breathe.
