What is the Best Duvet for Cold Nights?

Choosing the right duvet is essential for staying warm and cosy during chilly Winter nights. As the temperature drops, having the appropriate bedding to provide insulation becomes important to achieving a restful sleep. Why not wrap up and have a read through our guide to choosing a duvet for Winter? After all, staying warm is key during the later months of the year…

Understanding duvets

Duvets are thick, padded blankets filled with insulating materials such as down, feathers, or synthetic fibres – they are paired with a removable cover, which is how they differ from comforters or blankets, which tend to be a bit thinner, too. A duvet is designed to provide warmth when you’re in bed, typically in standard mattress sizes. Duvets trap and retain body heat, creating a cosy layer that helps regulate your body temperature during cold nights.

Factors to consider when choosing a duvet for cold nights

There are several factors to consider when choosing cosy bedding for low temperatures. These include the fill material and power as well as the tog rating and the size of the duvet itself. Let’s look at each of those in a bit more detail…

Fill material

Plenty of different fill materials are on the market, with some of the most popular being down and a down alternative. Down is the layer found underneath a bird’s features, and it’s naturally insulating, lightweight and cosy. Some down duvets are hypoallergenic, but it depends on the quality. Feathers are sometimes used in duvets, and they can be super thick but also quite itchy. There are wool duvets, which are very insulating, and bamboo duvets, which are thermoregulating, eco-friendly, and super soft. Bamboo is one of the best duvet fill types for cold nights because it intuitively adapts to your temperature to keep you feeling right as you drift off.


Fill power

The fill power refers to how much of the fill material is inside the duvet – and the more of it there is, the warmer your duvet should be. When you’re looking at cold-weather bedding options, opt for a higher fill power where possible.

Tog rating

When we talk about tog rating, this refers to how well a duvet retains heat during the night – essentially, how toasty you’ll be while you’re sleeping! Duvets are tested, and the higher the tog rating, the more heat it can retain. So, if you’re a cold sleeper, look at Winter duvet recommendations with a high tog – this tends to be how you can find the best duvet for cold weather.

Duvet size

As mentioned, duvet sizes typically correspond to mattress sizes: single, double, king and so on. Always be sure to check your mattress size when buying an insulated duvet for cold evenings because if your duvet is too small, you won’t feel cosy enough. It needs to be the right size for you and your bed!

Popular duvet options for winter nights

There are three really popular options for top-rated duvets for freezing nights: down, wool, and bamboo. Let’s snuggle in and have a look at each one in depth…

Down duvets

One really traditional duvet type is a down duvet; they are quite luxurious and super thick without being too heavy. They’re bound to keep you warm and cosy on cold Winter nights, but they can often be expensive and not always great for those with allergies.

Wool duvets

Wool is very insulating due to the crimped fibres – they create millions of tiny air pockets inside, working to trap the air itself and, therefore, slow the heat dissipation and transfer. This will keep you nice and toasty at night; wool is also hypoallergenic and moisture-wicking, making it a great option for a Winter duvet.

A bamboo duvet is one of the best you can get in terms of cold-weather sleep solutions. Not only is it soft and warm, but bamboo is also thermoregulating and temperature intuitive: it reacts to how hot or cold you feel in order to adjust, having you feeling just right for supreme levels of comfort. This is because the fibres gently expand and retract based on the temperature, so you’ll always feel snug as you snooze. And not only that, but bamboo itself is naturally antibacterial, hypoallergenic, and eco-friendly!

Maintenance tips for cold-weather duvets

Maintaining your duvet is key to years of cosy Winters. Follow the manufacturer’s instructions, and look into how best to care for the type of duvet you have; can it be machine washed, as most duvets can, and tumble dried? Down duvets definitely should go in the tumble drier, for example, but bamboo duvets should not. If you want to freshen up your duvet without a proper wash, shake it and hang it on the line (on a dry day!) to air it out a little bit.

Add a duvet cover to your duvet; this allows you to adapt it to the room’s decor and protects your duvet against spillages, germs and dust. This keeps it looking and feeling fresh for longer! When it comes to storing your Winter duvet during the warmer months, be sure to do so somewhere dry and airy to avoid mould and mildew from attacking your snuggly duvet.


The warmest duvet for chilly nights is one that feels cosy and soft on the skin, and has enough fill power and a high enough tog rating to keep you from feeling the chill in the air as you try to fall asleep. A thick and insulating duvet is key to getting a good night’s sleep during the colder months, which is ideal as this time of year can make us feel a bit down in the dumps. Make an informed decision by researching the top-rated duvets for freezing nights and choosing a material that suits you; we love bamboo, for its hypoallergenic nature and its thermoregulating properties.
