Duvet Buying Guide: How to Choose the Best Duvet for You

Choosing the right duvet can make a big difference to how well you sleep. From filling and tog to size and material, there are a few key things to consider before you buy.

In this guide, we’ll help you find the best duvet for your sleep style, room temperature and preferences, so you can create a comfortable sleep setup all year round.

Choose the right duvet filling

The filling of your duvet affects warmth, weight and breathability. The best option depends on how you sleep and your personal preferences.

Getting the right duvet filling can help really perfect that snuggling in and snoozing moment at the end of the day.

And, whether you’re a hot sleeper or you prefer to stay cool, we’ve got a duvet filling for you. However, with all these different duvet filling types, it can be difficult to know which one to go for. That’s why we’ve put together a duvet filling guide to help.

What is goose down duvet filling?

A goose down duvet is one of the most luxurious filling options available. But first, exactly what is goose down and why do we speak so highly of it? 

Well, these duvets are made from feathers found way down underneath the exterior feathers of a goose, nearest the chest. They are the softest and lightest feathers on geese and make an excellent natural filling for duvets, if you like to stay on the toastier side while you snooze. That’s because goose down duvet fillings trap tiny little pockets of air between the feathers, helping you stay warm all night. 

What’s more, when these feathers are packed together in a duvet filling, they create a bulky but light duvet, meaning you stay cosy without the faff of dealing with an unnecessarily heavy blanket.

Staying warm at night is all well and good, but what happens when you start to sweat? Good news! A goose duvet filling has a hygroscopic effect to help absorb moisture. This means that goose down is one of the best duvet fillings for a winter duvet.

Best for:

• Cold sleepers

• Winter use

• Premium feel

What is duck down duvet filling?

Similar to goose down, a duck down duvet filling is made from feathers found closest to the chest of the bird. However, what makes duck down stand out as a duvet filling is how breathable it is as a material.

Duck down is an excellent natural filling duvet for temperature regulation, keeping you warm - but not overheated - while you sleep. Feathers used in a duck duvet filling are often lighter than a goose down too, meaning your duvet won’t be quite as bulky. Perfect for keeping you cool if you’re a hot sleeper.

Best for:

• Balanced warmth

• Breathability

• Year-round use

What is synthetic material duvet filling?

Of course, not everyone wants to or can have a duvet made from bird feathers. If you’re after a more animal-friendly duvet filling, then our synthetic Feels Like Down duvets are ideal.

Filled with 100% hypoallergenic microfibre, a synthetic duvet filling is suitable for vegans, and those with allergies or skin irritations. The reason we call this duvet ‘Feels Like Down’ is because, while it is made from synthetic fibres, this duvet filling type is still just as cosy as our duck or goose down duvets.

So, if you want to experience the luxury of a down duvet filling, without the duck or geese feathers, then a synthetic material duvet filling is perfect. 

As a quick top tip, if you’re looking to get that goose and duck down warmth and cosiness from a synthetic duvet filling, go for a higher tog rating on your synthetic duvet.

Best for:

• Allergy sufferers

• Easy care

• Affordable option

Choose the right tog

Tog measures how warm your duvet is. The higher the tog, the warmer it will feel.

• 4.5 tog - summer

• 7 to 10.5 tog - spring and autumn

• 12 to 13.5 tog - winter

Choose the best duvet cover material

The right duvet cover can make just as much difference as the duvet itself. It affects how your bed feels, how breathable it is, and how well it holds up over time.

Here are the most popular duvet cover materials to consider:

Cotton

Cotton is one of the most popular choices for duvet covers. It’s breathable, soft and durable, making it ideal for everyday use.

It helps regulate temperature while you sleep, keeping you cool in summer and comfortable in winter. Cotton bedding is also naturally hypoallergenic, making it a great choice for sensitive skin. Within our whole bedding range, you'll find lots of 100% cotton options available.

Egyptian cotton

Egyptian cotton is a premium option known for its softness and long-lasting quality.

Made from longer fibres, it feels smoother and more luxurious than standard cotton. It’s also highly durable, so it maintains its comfort and finish wash after wash.

Ideal if you’re looking for a more elevated, hotel style feel.

Cotton sateen

Cotton sateen has a silky-smooth finish with a subtle sheen, giving your bed a more polished look.

It combines the softness of cotton with a slightly heavier, more draped feel. This makes it a great choice if you prefer a softer, more luxurious texture.

Choose the right duvet size

It’s nearly time to start piecing together your luxurious sleep haven - the last step is making sure you’ve got the right size duvet and cover for you. So, let’s take a quick look at sizes. 

There are a few options available so it can be tricky to know which size to choose. So, if you’re not sure what’s best, duvet covers in the UK generally come in four sizes and those are single, double, king, and super king. 

Each of these have separate dimensions, and to make this as easy as possible for you, we’ve outlined just how much comfy, cosy duvet comes in each size:

Best duvet cover size for your bed

Simply pick up the correlating duvet cover for your duvet size – single duvet cover for a single bed, double for a double – and let a satisfying sleep take hold. 

In terms of the best duvet size for your bed, you can follow the same instructions as for duvet covers. Many people size up for extra comfort and coverage. Choose a double duvet for a single bed, or a super king for a king bed. That way, you can truly lose yourself in sleep.

How to care for your duvet

Taking care of your duvet will help it stay comfortable and last longer.

Most duvets are machine washable, but always check the care label first. As a general guide, wash at a low temperature and use a gentle cycle, especially for feather and down fillings.

When drying, use a low heat setting and make sure the duvet is fully dry before using it again. This helps prevent clumping and keeps the filling evenly distributed.

To keep your duvet fresh between washes, air it regularly and use a duvet cover to protect it from everyday wear.

Duvet FAQs

What is the best duvet filling?

The best duvet filling depends on how you sleep. Feather and down duvets offer natural warmth and breathability, while synthetic options are hypoallergenic and easier to care for. The right choice comes down to your preferences and needs.

Which duvet is best for hot sleepers?

Hot sleepers usually prefer lightweight, breathable options. A lower tog duvet with a natural filling like duck down, or a breathable synthetic duvet, can help regulate temperature and prevent overheating.

What duvet is best for winter?

For colder months, a higher tog duvet between 12 and 13.5 tog is ideal. Feather and down duvets are a popular choice for winter as they trap heat effectively while remaining breathable.

Should I choose natural or synthetic?

Natural duvets, such as feather and down, are breathable and offer a more premium feel. Synthetic duvets are hypoallergenic, easier to maintain, and often more affordable. The best option depends on your budget, preferences, and any allergies.
