What is a duvet and why do you need one for winter?

A duvet is a type of bedding that consists of a soft, quilted cover filled with down, feathers, wool, silk, or synthetic fibers. It is usually used as the top layer of bedding, over a fitted sheet and under a decorative cover. A duvet provides warmth and insulation, as well as comfort and coziness.

A duvet is especially useful for winter, as it can help you regulate your body temperature and keep you warm without overheating. A good duvet can also improve your sleep quality, as it can reduce tossing and turning, and create a relaxing and inviting atmosphere in your bedroom.

How to choose the right duvet for winter: 3 key factors

When shopping for a new duvet for winter, there are three main factors that you should pay attention to: tog rating, material and filling, and size. These factors will determine how warm, comfortable, and durable your duvet will be. Let’s look at each factor in more detail.

Tog rating

Tog rating is an indication of the warmth of a duvet, specifically the level of thermal resistance. The higher the tog rating, the warmer the duvet. However, tog rating is not a reflection of the quality or weight of the duvet. This will depend on the material or fillings used.

Tog ratings range from 1 to 15, with 1 being the lightest and 15 being the heaviest. For winter, you may want to opt for a tog rating between 10 and 15, depending on your personal preference and how cold your bedroom gets. However, you should also consider your own body temperature and how hot or cold you feel at night. Some people may prefer a lower tog rating even in winter, while others may need a higher one.

Material and filling

The material and filling of your duvet will affect its softness, breathability, durability, and allergenicity. There are many types of materials and fillings available for duvets, each with its own pros and cons. Here are some of the most common ones:

  • Down: Down is the fluffy layer of feathers that lies under the outer feathers of ducks or geese. It is very soft, light, and warm, as it traps air and creates insulation. Down duvets are also breathable and moisture-wicking, which means they can keep you dry and comfortable throughout the night. However, down duvets can be expensive, require special care and cleaning, and may trigger allergies in some people.
  • Feather: Feather is the outer layer of feathers that covers the body of ducks or geese. It is firmer and heavier than down, but still provides good warmth and insulation. Feather duvets are also more affordable than down duvets, but they may not be as breathable or moisture-wicking. They may also make some noise when you move around in bed.
  • Wool: Wool is a natural fiber that comes from sheep or other animals. It is very warm, breathable, moisture-wicking, and hypoallergenic. Wool duvets can regulate your body temperature well, keeping you warm in winter and cool in summer. They are also durable and easy to care for. However, wool duvets can be expensive, heavy, and bulky.
  • Silk: Silk is a natural fiber that comes from silkworms. It is very soft, smooth, luxurious, and hypoallergenic. Silk duvets can also regulate your body temperature well, keeping you warm in winter and cool in summer. They are also lightweight and drapable. However, silk duvets can be very expensive, delicate, and require special care and cleaning.
  • Synthetic: Synthetic fibers are man-made materials that mimic natural fibers. They are usually cheaper, more durable, and easier to care for than natural fibers. They are also hypoallergenic and resistant to dust mites and mold. However, synthetic fibers may not be as breathable, moisture-wicking, or comfortable as natural fibers. They may also lose their shape and loft over time.


The size of your duvet should match or exceed the size of your bed, depending on your preference and how much you move around in bed. A duvet that is too small may not cover you adequately, leaving you cold and exposed. A duvet that is too large may hang over the edges of your bed, creating gaps and drafts. A duvet that is just right will fit snugly over your bed, creating a cozy and secure cocoon.

The standard sizes for duvets are:

  • Single: 135 x 200 cm
  • Double: 200 x 200 cm
  • King: 225 x 220 cm
  • Super king: 260 x 220 cm

However, you may want to opt for a larger size than your bed size, especially if you share your bed with a partner or like to wrap yourself in your duvet. For example, you may want to choose a king size duvet for a double bed, or a super king size duvet for a king bed. This way, you can avoid duvet hogging, leg kicking, or star-fishing, and enjoy a more peaceful and comfortable sleep.

Best duvet for winter: FAQs

Here are some frequently asked questions about choosing the best duvet for winter:

  • How often should I change my duvet? You should change your duvet every 5 to 10 years, depending on the quality and condition of your duvet. Signs that you need a new duvet include lumps, clumps, stains, odors, loss of loft, and reduced warmth.
  • How should I clean my duvet? You should follow the care instructions on the label of your duvet, as different materials and fillings may require different methods of cleaning. Generally, you should wash your duvet at least once a year, using a gentle cycle and mild detergent. You should also dry your duvet thoroughly, either in a tumble dryer or on a clothesline, fluffing it occasionally to prevent clumping. You should also air your duvet regularly, preferably in sunlight, to keep it fresh and hygienic.
  • How should I store my duvet? You should store your duvet in a cool, dry, and well-ventilated place, away from direct sunlight and heat sources. You should also use a breathable storage bag or cover, such as cotton or linen, to protect your duvet from dust, dirt, and insects. You should avoid using plastic bags or boxes, as they may trap moisture and cause mold or mildew.


Choosing the right duvet for winter can make a big difference in your sleep quality and comfort. By paying attention to the tog rating, material and filling, and size of your duvet, you can find the best option for your needs and preferences. A good winter duvet will keep you warm, cozy, and happy throughout the cold season.
