How we test duvets

We buy the bestselling duvets and put them through our tough tests. We don't accept freebies from product manufacturers or retailers. 

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 weigh each duvet and assess how easy it is to use and the overall quality. Each duvet is also washed according to its care instructions and examined afterwards for any defects. 

• Comfort Each duvet is rated by 40 testers for comfort and whether it's a suitable weight. By segmenting the results into those who prefer a light duvet and those who prefer a heavy one, we can recommend whether each duvet is most suitable for those who prefer a light or heavy duvet. Following this initial assessment with a large number of testers, the best duvets are taken home and slept under for a longer period for further testing and insight.
• Duvet weight Each duvet is weighed, then assessed by each tester for whether it's a comfortable weight to lie under.
• Build quality Each duvet is inspected for loose stitching, how easy it is to attach the two duvets if it's an all-season duvet, and how evenly distributed the filling is.
• Washing Each duvet is washed according to its instructions and then examined for loose stitching, wear and tear, and how evenly the filling is distributed. 

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.

What's the best duvet type for me?

Prices vary depending on the type of filling, tog rating, size and many other features. Some duvets can cost as little as £20, while others can cost more than £700.

Here's a rundown of the different types to help you choose what's right for you.

Synthetic duvets: pros and cons

Synthetic duvets, sometimes known as hollowfibre, are constructed 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 for comfort as feather and down options, and in some cases surpassed them.

• Pros Sometimes cheaper than other types, machine washable, some are hypoallergenic (meaning they're unlikely to cause an allergic reaction)
• Cons Typically last up to five years, which isn't as long as feather or silk (up to 10 years) and more expensive duvets; fillings can clump together

Feather and down duvets: pros and cons

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 feathers to down will affect the duvet's warmth and price.

Most feather-and-down duvets can be washed at home nowadays, either at 40°C or 60°C. But they can also be more difficult to dry properly than synthetic duvets, so consider the time of year before you start.

• Pros Retain heat, prevent overheating, last longer than synthetics if cared for properly, heavier (if you prefer heavy duvets)
• Cons Can be more expensive than synthetic, some people can be allergic to the filling, heavier (if you prefer light duvets)

Wool duvets: pros and cons

Wool is a less common choice of duvet filling. It's similarly priced to feathers and down but has the advantage of being naturally hypoallergenic and dust-mite resistant. Wool is renewable, sustainable and biodegradable, so it’s better for the environment than synthetic filling.

• Pros Retain heat, can prevent overheating, resistant to common allergens such as dust mites
• Cons Can be expensive, need to be washed gently at a low temperature, can seem flat compared with other fillings

Silk duvets: pros and cons

Often viewed as the height of luxury, silk duvets are naturally hypoallergenic and resistant to dust mites, and therefore good for people with eczema or asthma. 

• Pros Keep you warm while preventing overheating, naturally resistant to allergens
• Cons Expensive, need to be professionally laundered

Microfibre duvets: pros and cons

Microfibre duvets are a relatively new type, but they're not to be confused with hollowfibre duvets (although both are synthetic). Microfibres are finer and don't have the hollow spaces that hollowfibre has. Instead, microfibre is designed to be a synthetic equivalent to down and to 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, while others prefer a heavier, more closely hugging duvet.

• Pros Lightweight and soft, anti-allergen options available, often cheaper than down duvets
• Cons Don't regulate heat

Hypoallergenic vs anti-allergy duvets

Hypoallergenic doesn't mean the same thing as anti-allergy, so it's important to know the difference before buying.

• Hypoallergenic means that the duvet's material and filling aren't made of known allergens, such as feathers or wool. However, other allergens, mainly dust mites, can still develop on these types of duvets.
• Anti-allergy means the filling and casing will have been treated to resist and combat the development of dust mites. You might find that this type of duvet is good for you if you have asthma, eczema or rhinitis, all of which could be exacerbated by allergens. 

Whichever type of 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 important to check that it can withstand repeated washing at this temperature or higher every one to two months. Check our reviews before you buy.

If your duvet cover needs washing, but you're putting it off because it's a hassle to get your duvet back into it, here's the easiest way to do this

What tog duvet should I buy?

Duvet tog is a measurement of how thermally insulating, and therefore warm, a duvet is. 

What's the right tog?

Tog ranges from 1 to about 15. The higher the number, the warmer the duvet. Which tog you pick will depend on the time of year and your preference. You'll probably want a higher tog in the winter and a lower tog in the summer.

What tog is best for summer?

For the warmer months, look for a low tog between 1 and 4. These are lightweight and breathable duvets, so you won't overheat during summer nights. 

What tog is best for winter?

A high tog of 10.5 to 15 is better for winter. While 15 is the maximum, most people find that a 13.5 tog duvet is warm enough for British winters.

What tog is best for all year round?

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 the two.

Are all-season duvets worth it?

All-season duvets are a good option if you want to stay flexible through the unpredictable British weather with its ups and downs in temperature.

While they often cost a bit more upfront, an all-season duvet is usually cheaper than buying separate summer and winter duvets. 

How to wash a duvet

Most duvets, including all the ones we've tested, can be washed at home in your washing machine. We recommend doing this once or twice a year to keep yours fresh. 

Before you start, always check the care label. The best temperature and cycle will depend on whether the duvet filling is synthetic or natural. If you have a particularly heavy or expensive duvet and you're worried about damaging it (or your machine), you can also take it to the dry cleaners.

What is a duvet vs a comforter?

A duvet is designed to be tucked into a separate, washable cover, whereas a comforter is a single blanket that doesn't use one. 

Although popular in the USA, they're less favoured in the UK. They're also much harder to clean because the entire blanket has to go in the wash, instead of just a cover, when you want to freshen up your bedding. 

Should I buy an anti-allergy duvet?

To decide whether you should consider an anti-allergy duvet, check to see whether you have the symptoms of dust mite allergy:

• Watery, red eyes when you wake up
• Runny or itchy nose and sneezing in bed
• Sore throat or hoarse voice in the morning
• Coughing and other breathing problems
• Skin rash and itching
• Worsening of any existing asthma.

Get your symptoms checked out if you're not sure dust mites are the problem, just in case it's something more serious.
