All About Duvets: Tog Ratings, Fillings & Year-Round Comfort
The Duvet Guide
Few things make a bedroom more inviting than a beautifully comfortable duvet. From lightweight summer duvets to warm winter options, understanding tog ratings, fillings and seasonal comfort can help you create a bed that feels just right throughout the year.
A duvet may look like one of the simplest parts of your bed, but what is inside it can have a noticeable effect on how warm, light and comfortable it feels.
The right choice will depend on several factors, including your bedroom temperature, how warm you naturally sleep, the season and the type of filling you prefer. Our luxury duvet collection includes natural and alternative fillings in a range of weights and tog ratings, giving you plenty of choice when creating a comfortable bed.
What is a duvet?
A duvet is a soft, quilted bed covering filled with an insulating material such as down, feather, wool or a synthetic alternative. It is designed to hold warmth around the body while remaining comfortable enough to sleep beneath throughout the night.
The feel of one duvet can be very different from another. Some people prefer a light, lofty duvet that settles gently over the body, while others enjoy the more substantial feel of a heavier or warmer filling.
Rather than simply choosing the thickest duvet available, it is worth considering how much warmth you actually need. Your sleeping environment and personal preference are just as important as the season.
Understanding duvet tog ratings
A duvet's tog rating indicates its level of thermal insulation. In simple terms, a higher tog provides more warmth, while a lower tog provides less insulation.
There is no single tog that will suit everyone. Someone sleeping in a warm bedroom may prefer a lighter duvet even in winter, while a naturally cold sleeper may want more insulation.
A popular lighter option for warmer bedrooms, summer nights and people who tend to sleep warm.
A versatile level of warmth that can work well across much of the year depending on your room temperature and sleep preferences.
Provides greater insulation and is often chosen for colder bedrooms or the winter months.

Duvet fillings explained
Goose feather and down
Feather and down combine softness, loft and warmth. The balance between feather and down influences the overall weight and feel of the duvet.
Pure down
Down creates a particularly light and lofty feel, offering warmth without necessarily feeling heavy over the body.
Wool
Wool is a natural filling with temperature-regulating properties and a flatter, more even feel than a traditional lofty down duvet.
Alternative fillings
Modern synthetic and vegan alternatives can provide soft, practical comfort for people who prefer not to choose a feather or down filling.
Filling is a matter of personal preference. If you love the light, cloud-like sensation associated with luxury hotel bedding, a down-rich duvet may appeal. If you prefer a flatter natural filling, wool provides a very different sleep experience.
Alternative fillings can also be a practical choice, particularly where ease of care or personal preference is a priority.

Choose the right duvet size
The size of your duvet can affect both comfort and the overall appearance of your bed. A properly sized duvet should provide enough coverage to sit comfortably over the mattress and around the people sleeping beneath it.
Some people choose a duvet that matches their mattress size, while others prefer to size up for greater coverage or a fuller, more luxurious appearance.
It is also important to make sure your duvet works with the dimensions of your duvet cover. Bed and bedding dimensions can vary, so checking measurements rather than relying only on names such as King or Super King can help avoid a poor fit.

Layer your duvet for comfort and style
Once you have chosen your duvet, the surrounding bedding helps determine how the finished bed feels and looks.
Start with breathable cotton duvet covers and cotton pillowcases. Natural cotton creates a fresh, smooth layer around your duvet while giving the bed a clean and refined finish.
During colder weather, introduce blankets and throws at the lower part of the bed. These provide flexible extra warmth without requiring you to replace the duvet whenever the temperature changes slightly.
In warmer months, reduce the number of layers and allow the bed linen itself to create a lighter, fresher look.
How to look after your duvet
Looking after your duvet correctly helps preserve its filling, shape and comfort. Care requirements vary between materials, so always follow the instructions supplied with your particular duvet rather than assuming every filling can be treated in the same way.
Airing your duvet regularly and using a clean duvet cover can help keep it feeling fresh. When changing bedding, gently redistributing the filling can also help maintain an even loft.
If you switch between summer and winter duvets, store the one you are not using somewhere clean and dry. A breathable storage bag is preferable to compressing the duvet tightly for long periods.
Duvet FAQs
What tog duvet is best for summer?
A lower tog duvet such as 4.5 tog is commonly chosen for warmer weather because it provides less insulation. Your bedroom temperature and whether you naturally sleep hot or cold should also influence your choice.
What tog duvet is best for winter?
Higher tog duvets provide greater insulation, with 13.5 tog being a common warmer option. However, a well-heated bedroom or naturally warm sleeper may be more comfortable with a lower rating.
Can you use the same duvet all year round?
Yes, some people are comfortable with a medium-weight duvet throughout the year. Others prefer separate summer and winter duvets or an all-seasons duvet that combines different weights for greater flexibility.
Is down warmer than feather?
Down is valued for its ability to create loft and insulation while remaining lightweight. Feather adds more weight and structure, which is why many duvets combine the two materials in different proportions.
Should I buy a duvet larger than my bed?
Some people choose to size up for additional coverage or a fuller appearance. Always check the actual dimensions of the duvet and duvet cover before ordering, particularly because bedding sizes can vary between manufacturers and countries.
Can all duvets be machine washed?
No. Cleaning instructions depend on the filling and construction of the duvet. Some are machine washable, while others require specialist cleaning, so always follow the care label for your particular product.
Find your perfect duvet
The best duvet is ultimately the one that suits the way you sleep. Think about warmth, filling, weight and size rather than choosing on tog alone, then complete the bed with breathable cotton bed linen and layers that can be adjusted throughout the seasons.
