How to Choose a Duvet


Do you have a summer duvet? A winter duvet? Do you know your bedding tog rating? If you answered no to any of these, then this post is for you.

If you spend the summer getting in and out of your duvet because it’s too warm and wearing clothes in bed in the winter, then we’re here to tell you it doesn’t have to be this way!

We’re going to explain what bedding tog ratings mean, make some suggestions of what your summer duvet or winter duvet should be, and we’ll also recommend a good duvet for toddlers, who have different needs to older children and adults.

Read on for our expert advice on how to choose a good duvet for your home.

Duvet Togs Explained

The ‘tog’ of a duvet refers to its thermal insulance or in other terms, how warm it is. The Shirley Institute in Manchester launched their togmeter in the 1940s and it has become commonplace in the textiles industry ever since.

Duvet tog ratings are presented as numerical figures and there is a fairly sophisticated equation that goes into calculating them. It involves the R-value of a material, which you may have come across before with thermal insulation for your home, and how much heat passes through the material.

The highest tog duvet you can get is 15 tog. This will keep you exceptionally warm and toasty in bed. The lightest tog duvet is 1 tog. This is ideal for especially hot summer nights to avoid the bed sweats.

A 7-10 tog duvet is a good option for an all year round duvet, especially if you don’t fancy purchasing multiple duvets. Another good tactic would be to buy a light summer duvet and an all year round duvet. In the winter, if required, you can double these up for extra warmth.  

What Tog Duvet for Summer?

In the summer, you’ll want a light duvet. We recommend a tog rating of between 1 and 7 for your summer duvet. This is quite dependent on how you like to sleep, but in the UK a tog rating of 1 is probably too light even in the summer. Somewhere in the upper half of that range is normally a good bet.

What Tog Duvet for Winter?

For your winter duvet, you’re going to want to up your tog levels. A thick duvet of 10 tog and above should suffice. If you were to go all the way up to 15 tog, this is a really heavy duvet and might be too much even in the depths of winter. Again, this depends on your personal preferences.

What Tog Duvet for Toddlers

For a toddler, you must take extra care with the duvet you give them. Toddlers are not able to regulate their body temperature effectively, so do not give them a duvet that’s warmer than 4 tog.

For this reason, you’ll want to make sure your toddler’s room is kept at around 18 degrees centigrade. If it goes below 15, add some blankets to warm them up. If it goes over 21 degrees, reduce the number of layers.

Duvet Fillings

You have two options when it comes to the filling of your duvet. You can go for a  natural duvet or a synthetic duvet.

Natural Duvet Fillings

A natural filling is a really fantastic and effective duvet filling. They don’t tend to be as budget-friendly as synthetic materials due to the nature of the product, but when you consider the fact you spend roughly a third of your life sleeping in bed, it’s a worthwhile investment.

Natural duvet fillings include:


  • Silk

  • Wool

  • Feather

  • Down

Down-filled duvets typically are the warmest. Made from feathers from the breast area of a duck or goose, these make for a very comfy night’s sleep. Silk is a really good option for people with allergies that want a natural duvet filling. Wool is, quite obviously, fantastic for trapping heat and great option for the winter.

Synthetic Duvet Fillings

Synthetic duvet fillings are inexpensive and ideal for people with allergies. They’re much easier to wash than natural fillings and good for those who get the bed sweats.

There are two categories of synthetic duvet filling:


  • Hollowfibre

  • Microfibre

Hollowfibre duvets are hard-wearing and when stuffed into a duvet, they trap warmth really well. Microfibres are exceptionally fine fibres that give a similar feeling to high-quality natural down duvets. They’re lighter than hollowfibre duvets which tend to be thicker and warmer.
