How to Choose the Right Duvet?

How to Choose the Right Duvet?

Understanding how to choose the right duvet is really important to ensure you're comfortable and well-rested every night. Navigating the different duvet fillings, tog ratings and sizes can be confusing, so we're here to provide a helping hand. This guide to choosing the right duvet will answer all of your questions, so let's get started!

Duvet Filling Guide

When it comes to choosing the right duvet filling, you first need to decide between a natural filling and a synthetic filling. Duvets with a natural filling are typically longer-lasting, lighter, better at insulating and more pricy. On the other hand, duvets with a synthetic filling are typically easier to care for, good for allergy sufferers and more affordable. Our duvet filling guide will cover five of the most popular options. 

Natural Duvet Fillings:

Feather- & Down-filled: One of the most-loved natural duvet options, feather- and down-filled duvets offer a host of benefits. They're filled with a combination of feathers and down fibres from either geese or ducks and, in turn, they're ideal for providing temperature control. Using a combination of feather and down fibres enables sleepers to reap the benefits of both. Down fibres are super soft, lightweight, and the most insulating. Feathers are also effective insulators but are more robust and affordable than down fibres. Feather- and down-filled duvets are long-lasting and extremely comfortable, however they require professional cleaning. 


- The best option for insulation

- Extremely soft 

- Long-lasting with proper care

- Breathable

- Typically more expensive than synthetic alternatives

- Not suitable for individuals who are allergic to feathers

- Require professional cleaning 

Silk: For a touch of luxury, a silk duvet is a popular choice. Silk is a fabric that offers effective temperature control, keeping you cool in the heat and warm in the cold. It's also a very light material and hypoallergenic. However, it can be an expensive choice of duvet and needs professional cleaning. 


- Temperature control

- Lightweight 

- Luxurious

- Hypoallergenic

- Usually a pricier option 

- Requires professional cleaning

- Not the cosiest fabric 

Wool: Wool is another natural fibre that's great at regulating body heat. Its chunky structure helps to trap heat when you're cold, and its moisture-wicking properties help to keep you cool when you're hot. Wool can feel flat in comparison to feather- and down-filled duvets, however it's resistant to dust mites. 


- Moisture-wicking properties 

- Resistant to dust mites 

- Can be expensive

- Can feel flat 


Synthetic Duvet Fillings:

Hollowfibre: If you're leaning towards a synthetic duvet filling, a hollowfibre duvet makes a great choice. The fibres used for this type of duvet are, as the name suggests, hollow, which allows for warmth to trapped more easily. A hollowfibre duvet is ideal if you're an allergy-sufferer because the fibres are synthetic. It's also machine-washable and can last up to five years with appropriate care. 


- Typically more affordable than natural duvets

- Can be machine-washed, so easier to care for 

- Good for allergy-sufferers 

- Effective at regulating body temperature

- Not as durable as natural duvets 

- Not as insulating as natural duvets   

Microfibre: A microfibre duvet is another great example of a synthetic duvet. Microfibres are much finer than hollow fibres, meaning a microfibre duvet is much lighter and softer. They are designed to emulate the softness of a down-filled duvet, however they don't regulate heat as effectively. Microfibre duvets are usually more affordable, though, and can be machine-washed at home. 


- Effective temperature control

- Lightweight 

- Soft 

- Typically more affordable than natural duvets  

- Can be machine-washed, so easier to care for

- Not as long-lasting as a naturally filled duvet

- Not as effective at regulating heat compared to down-filled duvets 

Guide to Duvet Togs

How to choose the right duvet tog? The tog rating is a simple way of referring to how well the duvet is able to trap the air around you to provide warmth and insulation. It's not to be confused with duvet weight which will vary depending on the filling and quality. As a general rule, the higher the tog, the warmer the duvet will be. Tog ratings range from 1.5 tog to 15 tog. 

In the UK, the guide to duvet togs is as follows: A 4.5 tog is ideal for a lightweight, summer months duvet; however, for the colder winter months, a 13.5 tog offers extra warmth and cosiness.

For many of us, the cost of two separate duvets isn't justifiable, so finding a middle-ground is important. A 10.5 tog would be an excellent choice for year-round suitability and comfort. 

Of course, these are just guidelines as choosing the right duvet tog is also dependent on your personal preference and sleeping set-up. If you sleep with a partner, you might want a lower tog to compensate for the extra body heat. Or, if you get cold easily, you should consider a higher tog so you're always comfortable. 

Take into account these additional factors when choosing the right duvet tog: climate, sleepwear, central heating, duvet quality, duvet size, personal body temperature, sleep partner and bedroom ventilation.

How to Choose the Right Duvet for Children

Choosing the right duvet for children, toddlers and babies is crucial for their wellbeing. Children naturally have more body heat than adults, so you shouldn't give them a duvet that's too heavy or that has a high tog rate. Also, as children have smaller bodies, a duvet will trap more warm air around their body. This means that a duvet with a high tog rate will keep your child warmer than it will keep you, so they face an increased risk of overheating. 

As a child grows, the tog of their duvet can increase gradually. However, children under the age of ten should not use a duvet that exceeds a 10.5 tog rating. And, remember that babies under the age of 12 months should not use a duvet. Any duvet will be too hot and heavy for them, which can lead to suffocation. 

Choosing the Right Duvet Size 

The standard UK duvet sizes are as follows:

Cot: 120cm x 150cm

Single: 135cm x 200cm

Double: 200cm x 200cm

King: 230cm x 220cm

Super King: 260cm x 220cm

Emperor: 290cm x 235cm 

To get the right duvet size, be sure to measure your mattress carefully. Our mattress size guide is full of helpful advice if you're looking to change mattress size. 

Many people will choose a duvet size that's one size larger than their mattress size. This enables the duvet to hang over the edges slightly, providing added comfort. You may also want to size-up when it comes to your duvet if you're tall or if you're sharing the bed with somebody else. 

Duvet Weight Guide

The fill weight of a duvet depends on a number of factors including fill power and fill type. Duvet weight is measured in 'gsm', or grams per square metre, and it is not a direct indicator of duvet warmth. So, just because a duvet is heavy, it doesn't necessarily mean its warmer. 

For example, down-filled duvets are typically better at insulating compared with synthetic alternatives. As a result, down-filled duvets may have a low fill weight but a high tog rating. 

Choosing the right duvet weight depends on your personal preferences. So, take the fill weight into account when making a decision on your ideal fill type and tog rating. 

We hope that this guide to duvet togs, duvet fillings, duvet sizes and duvet weight has been useful and that you're now feeling confident with how to choose the right duvet for you! There are a lot of choices to consider, and a good quality duvet should provide several years of comfortable sleep.
