Do Wool Mattress Toppers Keep You Cool at Night?

If you have a high-stress job, you already know how difficult it can be to switch off at the end of a long day. Racing thoughts and looming deadlines often lead to restless nights, leaving you tossing and turning. When anxiety creeps in, your core body temperature can rise, causing uncomfortable night sweats that completely disrupt your sleep cycle.

You might assume that adding another layer to your bed would only make things worse. Thick, synthetic materials trap heat and moisture, turning your mattress into an inescapable furnace. However, natural materials interact with your body in a completely different way.

Replacing synthetic bedding with a breathable, natural layer could be the simple change you need to transform your rest. If you want to know whether a Wool Mattress Topper can actually lower your temperature and help you sleep soundly, you are in the right place.

What Is a Wool topper mattress?

A Wool topper mattress is a cushioning layer that sits directly on top of your existing mattress, underneath your bed sheet. Unlike standard memory foam or polyester alternatives, these natural toppers utilise the unique properties of wool to enhance your sleeping environment.

At Putnams, our Natural 100% British Wool Mattress Topper is handmade in Devon.

We use a thick 600gsm quilted British wool encased in a 100% cotton cover. It features elastic arms on each corner to keep the topper secure, ensuring it stays perfectly in place even if you move around during the night.

Are wool mattress toppers any good?

When upgrading your bedroom, it is entirely normal to ask: Are wool mattress toppers any good? The short answer is yes, especially if you struggle with broken sleep or overheating.

Scientific research strongly supports the benefits of wool for sleep quality.

A study conducted by researchers at The University of Sydney found that adults wearing wool sleepwear fell asleep in just 12 minutes. The natural thermo-regulating properties of the material calm the nervous system, which is crucial for professionals trying to wind down after a demanding workday.

Beyond temperature control, wool toppers for mattresses provide a soft, supportive layer that relieves pressure points. If your current mattress feels slightly too firm, adding this plush layer creates a comfortable surface without sacrificing necessary spinal support.

Do Wool Mattress Toppers Keep You Cool?

Yes, wool mattress toppers actively keep you cool. It sounds counterintuitive, but we associate wool with thick winter jumpers. Yet, wool functions as a natural climate control system for your bed.

Here is exactly how it works:

• Moisture Wicking: Wool fibres pull perspiration away from your skin. In fact, wool can absorb up to 30% of its own weight in moisture without feeling damp.
• Breathability: The absorbed moisture is then released back into the air. This constant airflow prevents the clammy, sticky sensation often caused by synthetic foam.
• Temperature Regulation: When you are warm, the fibres draw away heat. When your bedroom drops in temperature, the natural crimp in the wool traps small pockets of air to insulate you.

For UK shoppers seeking breathable bedding, Wool Mattress Toppers are a highly effective solution for year-round comfort.

How to clean a wool mattress topper

Maintaining your bedding ensures it lasts for years while keeping your sleep environment hygienic.

If you are wondering how to clean a wool mattress topper, the process is remarkably straightforward but requires gentle care to protect the natural fibres.

Follow these simple instructions for the Putnams British Wool Mattress Topper:

• Air it out: The best way to refresh your topper is to hang it outside on a dry, breezy day for a few hours. Wool is naturally antibacterial and self-cleaning, so fresh air easily removes any lingering odours.
• Dry clean only: If your topper suffers a heavy spill or requires a deep clean, take it to a professional dry cleaner.
• Avoid washing machines: Never put your 100% wool topper in a domestic washing machine or tumble dryer, as the heat and agitation will cause the natural fibres to shrink and clump.

FAQs for Wool Mattress Toppers

Is a wool mattress topper hot in summer?

No, wool mattress toppers are not hot in summer.

Wool is a breathable material that naturally regulates temperature, helping to wick away moisture and keep you cool during warmer months. Its insulating properties work to maintain a comfortable sleeping environment, no matter the season, making it an ideal choice for year-round use.

Do Wool Mattress Toppers Keep You Cool at Night all Year Round?

If you struggle with overheating, you’ve likely wondered, "Are wool mattress toppers any good?" Contrary to what many think, wool isn't just for winter.

At Putnam's, our range of wool mattress toppers is designed to leverage natural science to optimise your sleep climate. Is a wool mattress topper hot in summer?

No, quite the opposite. A wool topper mattress is one of the most effective cooling layers available. Data shows that wool can absorb up to 30% of its own weight in moisture without feeling damp. This process, known as "desorption," pulls sweat away from your body and evaporates it into the air.

While synthetic foams can increase skin temperature by several degrees, studies indicate that sleeping on wool can help maintain a lower, more stable heart rate and a skin temperature closer to the ideal 33°C.

This makes wool mattress toppers the UK's summer's best-kept secret for deep, uninterrupted sleep.

What is the coolest material for mattress toppers?

Natural wool is widely considered the coolest material due to its unmatched breathability. In a side-by-side comparison with memory foam and polyester, wool has a significantly higher "thermal resistance" (R-value) and moisture-wicking capacity.

Our wool toppers for mattresses utilise British wool fibres that create a micro-climate. Unlike memory foam, which acts as an insulator and traps heat, wool allows for constant airflow. This "dry heat" is much more comfortable for the sleeper than the humid, trapped heat of synthetic materials.

What is the point of a wool mattress topper?

The primary goal of a wool mattress topper is to create a healthy, ergonomic, and temperature-regulated sleep environment.

Beyond cooling, it provides:

• Pressure Relief: It cushions the body, reducing "tossing and turning" by up to 25%.

• Hypoallergenic Properties: Wool is naturally resistant to dust mites and mould.

• Durability: A Putnams topper is a long-term investment in your health.

To maintain these benefits, knowing how to clean a wool mattress topper is essential.

We recommend regular airing and gentle spot cleaning to keep the natural lanolin and loft of the fibres intact for years of use.

Will a mattress topper help with sciatica?

Yes, a high-quality wool mattress topper can significantly alleviate sciatica pain.

Sciatica is often exacerbated by hard surfaces that put direct pressure on the sciatic nerve.

By adding a 2–3 inch layer of wool, you provide "soft support" that contours to the lumbar spine. This helps keep the spine in neutral alignment, reducing the nerve compression that leads to shooting pains down the leg. For those suffering from chronic back issues, Putnams recommends wool for its ability to provide relief without the "sinking" feeling that can make moving in bed difficult for sciatica patients.
