The best duvets give you that just right cosy feeling when you snuggle down to sleep.
We've enlisted the help of more than 40 testers to help you find a cosy and great-value duvet. Our testing also reveals which duvets are preferred by sleepers who like a lighter option and those who prefer a heavy one.
We've tested a mix of winter and all-season duvets with synthetic or natural feather fillings.
We've also discovered that the best duvets needn't break the bank. Our Best Buy recommendations start from around £50 and we've also found a Great Value recommendation that's among the cheapest we've tested.

We recruit a 40 strong army of testers to put each duvet through its paces for comfort, and we also send the best duvets home with researchers for further testing over a longer period. Each duvet we test is king size.
In addition to comfort tests we also weigh each duvet, and assess each one for how easy it is to use and the quality of the overall product. Each duvet is also washed according to its care instructions and examined afterwards for any defects.
We regularly revisit the duvets on sale to see if there are any more popular ones that need testing and when we find them we do.

Prices vary depending on the type of filling, the tog rating, size and many other features. Some duvets can cost as little as £20, while others can cost more than £700.
Synthetic, sometimes known as hollowfibre duvets, are made from man made materials and can sometimes be cheaper than feather or wool duvets.
The best synthetic duvets in our test scored just as highly, and in some cases higher, for comfort with our testers as feather and down duvets.
Synthetic materials can be good for allergy sufferers, as they're less likely to cause an allergic reaction.
They can lose their tog value more quickly than natural alternatives and therefore don’t last quite as long, although a hollowfibre duvet should still last at least five years, if cared for properly. Duvets with natural fillings such as feather and down or silk can last as long as a decade.
Feather duvets tend to be heavier than their synthetic counterparts, which will either be a pro or a con, depending on your preference.
As the name suggests, feather and down duvets combine feathers (the outer part of a bird’s plumage) with down, the lighter, fluffier fibres that lie beneath feathers and provide insulation. The ratio of feather to down will affect the duvet's warmth and price.
Most feather and down duvets are able to be washed at home nowadays, either at a 40°C or 60°C wash. Read our reviews for washing instructions. They can be more difficult to dry properly than synthetic duvets, so consider the time of year before you start.
Wool is a less common choice of duvet filling. It's similarly priced to feather and down, and excellent at retaining warm air, keeping you warm when cold as well as removing heat and moisture when you’re warm. Unlike feather and down, it’s naturally hypoallergenic and resistant to dust mites.
Wool is renewable, sustainable and biodegradable, so it’s better for the environment than synthetic fillings.
However, you'll need to be careful when looking after a wool duvet – washing too often and at too high a temperature will reduce its lifespan.
Often viewed as the height of luxury, silk duvets are naturally hypoallergenic and resistant to dust mites, and therefore ideal for people with eczema or asthma.
Like wool, silk will help you stay cool in summer and warm in winter. Like most natural fillings, though, they will need to be professionally laundered.
Microfibre duvets are a relatively new type, but they aren't to be confused with hollowfibre – both are synthetic materials. However, microfibres are finer and don't have the hollow space that hollowfibre has. Instead, microfibre is intended to be a synthetic equivalent to down and its extra-fine fibres give the same feel.
It's one of the lightest and most supple fillings, meaning even a 14 tog microfibre duvet will feel light. Some people prefer this as the duvet won't feel heavy on you, while others prefer a heavier, more closely hugging duvet. If you're not sure which you'd prefer, read our reviews.
While microfibre feels similar to down, it's lighter and often cheaper. So if you've always had natural duvets but are looking for a slight change, microfibre might be for you.
Hypoallergenic doesn't mean the same thing as anti-allergy, so it's important to know the difference before buying.
Whichever duvet or pillow you buy, dust mites can be killed and their allergens removed by washing at temperatures of 60°C or above. If you're looking for bedding to help with allergies, it's therefore important to check that it can endure repeated washing at this temperature or higher roughly once every one to two months. Read our reviews for washing instructions.
If your duvet cover needs washing, but you're putting if off because of the effort involved in getting your duvet back into it, here's the easiest way to do this
To know if you should consider an anti-allergy duvet, you should check to see if you have the symptoms of dust mite allergy:
Get your symptoms checked out if you're not sure dust mites are the problem, in case it's anything more serious.
Duvet tog is a measurement of how thermally insulating, and therefore warm, a duvet is.
Tog ranges from 1 up to about 15. The higher the number, the warmer the duvet. Which number tog you pick will depend on the time of year and your preference. You'll likely want a higher tog in the winter and a lower tog in the summer.
The highest tog is about 15, but most winter duvets are sold at 13.5, which is warm enough for British winters.
A high tog (10.5 to 15) is better for winter, while a low tog (1 to 4) will be light enough for summer.
Some duvets come in 'four-seasons' or 'all-seasons' sets. With these you get one light duvet (usually about 4.5 tog) and one heavier one (usually about 9 tog). The light one will be enough in hot summer months and the heavy one suits spring and autumn weather. When you need extra warmth in winter, you can combine both.
