The ideal duvet is key to restorative sleep, providing comfort through every season. Our duvet tog guide brings clarity to the technical scale of tog ratings, helping you select a layer that balances luxury with breathability for yearly harmony. Read on as we explore the duvet tog differences to help you choose the definitive duvet from the Feather & Black collection - an investment designed to see you seamlessly through the seasons and into a state of weightless repose.
Duvet tog rating explained
“In technical terms, a tog rating (Thermal Overall Grade) is a measurement of thermal resistance. The lowest tog duvet (4.5) is lightweight and designed for maximum airflow, while the highest tog duvet (15) is the ultimate barrier against mid-winter chill. By using tog ratings, we can quantify a product’s ability to trap air and retain heat with mathematical precision.”

Recommended tog ratings by season
In our experience, the duvet tog rating is the best starting point for choosing the perfect duvet. It gives you a baseline from which to explore your personal comfort needs from summer through to winter. We’ve curated this duvet tog rating chart to bring clarity to your definitive selection from our luxury duvet collection.

The composition of comfort: Selecting your filling
The material in your duvet serves as a responsive regulator for your evening, instinctively managing the environment beneath the covers to suit your silhouette. Natural materials possess an inherent ability to breathe in tandem with your body’s natural rhythms, offering intuitive comfort that synthetic alternatives strive to replicate.
Hungarian Goose Down duvets contain clusters that expand to create loft, trapping warmth while feeling light. While many expect this to feel overbearing as it’s the thickest tog duvet, premium down offers a deep, yielding submersion without downward pressure, allowing for effortless movement throughout the night.
Alternatively, a duvet containing British Wool stands as a masterpiece of natural engineering. These fibres are moisture-wicking by design, pulling humidity away from the skin to maintain a dry, consistent heat. This is a resolute choice for an all-year-round duvet tog, ensuring your sleep environment remains steadfast even as your internal temperature fluctuates.
“Anyone who’s worn a woolen jumper on a sunny day will attest to the surprising comfort you feel. Wool is naturally designed to maintain a temperature, not increase it by retaining heat. The same applies to wool duvets and mattresses.”
For those who require hypoallergenic properties, our Soft as Down duvet is engineered to mimic natural fillings. These extra-fine microfibres provide a consistent, unwavering loft that remains resolute through frequent laundering - a definitive alternative for sensitive sleepers.
Maintaining the loft of your duvet
To maintain the integrity of your duvet and ensure it continues to enhance your rest, we recommend regular duvet maintenance. Gently shaking the duvet each morning redistributes the filling within its Baffle Box construction (the ‘patch’ grid that prevents the filling from bouncing at the bottom of the duvet). Regular aeration allows air to move freely through the fibres, ensuring even a heavy tog duvet remains buoyant and restorative rather than compressed.
How to choose a duvet tog for your bedscape
Selecting the definitive tog rating can require a bit of experimentation. Your body and your bedroom’s climate all play a role in how you feel in bed. This is why tog ratings are so helpful; they give you a baseline from which to start your comfort journey. But ultimately, we believe that the choice is personal.
"We often see sleepers assume they need the highest tog duvet simply because it’s winter," notes Louise Silver, Product Technologist. "But, if you live in a well-insulated, modern home or experience natural warmth during the night, a 15-tog layer will feel overbearing."
When choosing your personal tog rating, consider these three guiding principles:
- Ambient Climate: For temperate bedrooms, a 10.5 tog serves as a steadfast, breathable all-year-round duvet tog.
- Physical Needs: Naturally warm sleepers should seek our lowest tog duvet (4.5) for refreshing, barely-there comfort.
- The All Seasons Approach: Pair 4.5 and 9.0 tog layers to adjust your thermal resistance in tandem with the seasons, reaching a maximum tog duvet for the depth of winter.
