The Difference Between 10.5 Tog and 13.5 Tog?

Getting cost and all snuggled up in your own bed is something we all look forward to after a long day, and since we spend around a third of our lives in bed, it’s pretty essential to make the best of it.

A duvet plays a vital role in our comfort when in bed, and choosing the right one can be the difference between a hot, sweaty sleepless night and a comfortable Goldilocks sleep that is just right.

This guide discusses the difference between a 10.5 tog duvet, a 13.5 tog duvet, and everything in between.

We give helpful tips on choosing the perfect duvet for you, what kind of duvet is best for winter and some examples of our luxurious duvets so you can sleep soundly at night, like the Virgin Egyptian Cotton All-Season duvet. Simply divine!

A guide to the tog duvet rating

Contrary to what people think, the tog rating doesn’t mean how thick a duvet is. The tog is a measurement used to indicate the effectiveness of the thermal insulator of a material. In other words, the tog tells you how warm the duvet will keep you.

Basically, the lower the tog rating, the cooler the duvet, so the higher the tog rating, the warmer the duvet. So it makes sense that many people change their duvet seasonally because we need more warmth in the colder months than during the warmer months.

To answer the question, what is the difference between a 10.5 tog duvet and a 13.5 tog duvet? The 10.5 duvet will keep you cooler at night than the 13.5 tog duvet. The bedding comfort store stocks a range of duvets, including Soft Touch Duvets that come in togs from 1.5-15, so there is something for everyone.

Choosing the right duvet for the time of year

For optimum comfort, it is recommended that you swap your duvet top seasonally. Ideally, you should have 3 duvets per bed, one for summer, one for winter and one for autumn and spring.

However, this option isn’t for everyone. Keeping 3 duvets per bed is likely a struggle. Or maybe you like to keep things simple and have enough on your plate without worrying about changing your duvet. If this sounds like you, choosing a multi-season duvet will be your best option.

Here is your guide to which duvet tog you should choose for the time of year and some options for all-year-round duvets.

Winter tog duvet

Higher tog duvets are best for winter because they are better insulators. Therefore, they will keep you warmer. The best winter duvets are 13.5 to 15 tog, and these are also great for older houses with less insulation or for people who generally have a low body temperature and feel the cold more easily.

Choosing the perfect winter duvet depends on personal preference, but generally, stick to the higher tog duvets for ultimate warmth.

13.5 tog duvet

The 13.5 tog duvet is ideal for people who want one that will keep them warm during winter but struggle with night sweats or overheating.

Many people wonder if a 13.5 tog duvet is too thick or if it will cause them to overheat, and the answer to this will differ from person to person. If you enjoy a warm duvet and often wake up shivering at night, then the 13.5 should be a great choice.

If you sleep with their feet hanging out of the covers and kick the duvet off them at every chance, then the 13.5 might be too warm a duvet for you.

Spring and Autumn tog duvet

Spring and autumn are between seasons when nobody knows what to wear. Should you wear a jumper and jeans or shorts and a T-shirt, who knows with the British weather? The same can be said for at night; what duvet should you use?

The best choice is to choose a duvet tog between 10.5 and 13.5. Again, choosing one depends on personal preference, your usual body temperature and how hot or cold your house is.  Older houses tend to lose height more quicker than newer houses.

Summer tog duvet

In summer, you’ll want the lightest tog duvet or one with a low tog rating. Most of us love the sunshine and the heat and spend hours enjoying it with our family and friends.

But when it comes to nighttime, we complain it is too hot to sleep, but having a lightweight, breathable duvet can make a big difference. In summer, you’ll want the lightest tog duvet or one with a low tog rating.

For hot sleepers during the hottest time of the year, a 2.5 tog rated duvet would be best. For people who find themselves cold when everyone else is warm, try a 4.5 tog duvet, as this will give you a little more warmth than the 2.5 without overheating.

Multi-season duvets

But what tog duvet is best for all seasons if you don’t want the hassle of changing it or having the storage? The 10.5 tog duvet is the best choice for a Goldilocks duvet; it’s not too hot or cold, but just right, just like this Dobby White All Season duvet.

10.5 tog duvet

The 10.5 is a great all-rounder because it is in the middle of the tog rating, meaning that it is a good insulator, so it’ll keep you warm but not too warm.

In peak winter, when snow is on the ground and frost in the air, you might need an extra blanket to give you extra warmth. When the BBQs are fired up, and the sun cream is out in peak summer, you might want to sleep with your feet hanging out.

Duvet Fillings

The duvet tog isn’t the only difference between duvets. Duvets are filled with different materials, which is how they are given their tog rating. There are two types of duvet fillings, synthetic and natural, and within those two categories, different materials are used.

Here is your guide to synthetic and natural duvet fillings.

Synthetic duvet

Synthetic means it is made by chemical synthesis; in other words, it is artificial. Many people opt for synthetically made duvets because they are hypoallergenic, cheaper than natural duvets and free from animal products.


Hollowfibre is a synthetic material that is made up of a vast number of distinct strands. The strands contain a hollow centre that traps air and makes them breathable. If you want a lightweight yet airy duvet, you can’t go wrong with a hollowfibre one.

These duvets provide the same level of warmth as down duvets but as less heavy. Hollowfibre duvets are sturdy and can hold their shape well. Due to their breathability, microfibre duvets are ideal for people that sweat at night.


Microfibre duvets contain millions of tiny fibres that are woven together. The compactness of the fibres provides a good level of warmth. These duvets are plump, lightweight and an excellent alternative to down duvets.

Microfibre is the lightest synthetic fibre duvet but still offers ultimate warmth. These duvets are perfect for people that want a snug and cosy duvet.

Natural duvet

Natural duvets have a luxurious feel and are more expensive than synthetic duvets due to their animal product content. Two of the most popular types of natural duvet fillings are duck down and goose down.

What is down?

Down is a layer found beneath the feathers of ducks and geese. Down’s primary purpose is insulation, making it an excellent material for duvet fillings.

The down insulates through a process called lofting. The down material expands to fill space and trap thousands of insulating air pockets within the filament. As well as down, some duvets are filled with feathers, which gives the duvet a firmer feel than a duvet without feathers.

Duck down duvets

Duck-down duvets are usually a little less expensive than duck-down duvets and are typically the lower end of natural duvets. Still, they are fluffy and warm and aren’t far different from goose-down duvets.

Goose down duvets

Goose-down duvets are usually more expensive than duck-down duvets and are superior insulators. They tend to be lovely and plush and have a more luxurious quality.

A final note

What’s the difference between a 10.5 tog and a 13.5 duvet? The 10.5 will keep you cooler than the 13.5. The 10.5 is an ideal four-season duvet for those that don’t want to change over, or it is great for autumn and spring. The 13.5 duvets are suitable in winter as they’ll keep you warm.
