What Exactly Is a Duvet Tog?

Person Sleeping - Duvet Tog Guide

A duvet's tog rating indicates how warm it will be. The higher the tog rating, the warmer the duvet. Lower tog ratings provide lighter and cooler options.

TOG stands for thermal overall grade. This measurement unit calculates a product's thermal insulation, usually in the textile industry. The higher the tog, the toastier the duvet is going to be.

Understanding Tog Rating

When choosing a duvet, the tog rating is one of the most critical factors. That’s because this number directly corresponds to how warm or cool a duvet will be. A duvet with a higher tog rating best suits colder weather, while lower tog ratings are perfect for warm summer nights.

What Affects Duvet Tog Ratings?

The tog rating of a duvet can’t always be deduced by touch or sight. It depends on various factors, such as the type of filling used in the duvet. Synthetic materials (hollowfibre) are often less thermally insulative than natural materials (sheep’s wool). 

It takes more synthetic fibre to produce the same tog rating as an equivalent natural-fibre duvet. 

A thicker duvet doesn’t necessarily mean warmer. Natural fibre duvets can sometimes feel lighter than synthetic duvets, but this doesn’t mean they are less thermally insulative. Natural fibres can trap air better than artificial fibres, providing more warmth, which is especially noticeable in those cold winter months.

Different Tog Ratings for Different Seasons 

The higher the number of togs, the more cozy warmth you’ll receive. Now, there are numerous levels of duvet tog ratings:  

  • 1-4.5 Tog Duvets: The perfect range for warm summer days.

  • 7-10.5 Tog Duvets: The ideal all-seasons solution.

  • 10-13.5 Tog Duvets: The right choice for the depths of winter. 

Duvet togs can also be affected by the type of filling used to create them. It usually takes more materials to create a synthetic duvet with the same tog level as a duvet made with natural fibres.

Do Duvets Lose Their Tog Ratings?

After continuous nights of blissful sleep, duvet togs can lose their levels of warmth as the fillings get less fluffy. Their level of heat retention starts to decrease. If you ever need an extra blanket on those chilly winter nights, you may need to replace your current duvet with a new one.

What Factors Influence the Right Duvet Tog for You?

Finding the right level of tog to ensure you have a comfortable night of peaceful sleep can depend on various key factors, such as:  

  • Body heat

  • Sleeper types

  • The time of year 

  • Environmental factors, like the temperature of your bedroom 

  • If you share a bed

The Perfect Duvet Tog for Every Season at a Glance

Woman Sleeping - Duvet Tog Guide

Duvets have a range of different measurements that help quantify their warmth. The most common, and useful, measurement is the duvet tog rating. The higher the tog rating, the warmer the duvet will be. A 1 tog duvet will be very thin and lightweight, while a 13.5 tog duvet will feel:

  • Thick 

  • Heavy

Duvets with lower tog ratings are best suited to summer, while higher tog ratings are designed for winter use. Most togs fall between 4.5 and 13.5, with anything around 10.5 being a good all-season option.

Factors to Consider When Choosing Duvet Togs

When deciding what tog rating would give you the best night's sleep, there are likely to be many factors that contribute to your choice, such as:

  • If you share a bed with a significant other

  • The type of sleeper you are

  • The ideal temperature of your bedroom

When choosing the right tog rating for your loved ones, specifically children and teenagers, there is a bit more to consider.

Duvets for Children

We all know how essential it is for children to get good quality sleep, not just for them but us. Your child's age will factor into which tog rating is best for them. Younger children need lower tog ratings to prevent overheating that thicker duvets can lead to. Usually, a 4.5 tog rating will be suitable for a child to sleep soundly.

What Duvet Tog Is Right for My Teenager?

Deciding on the right duvet tog for your teenager is a far less complicated process than choosing one for a child, especially as they are more likely to be better at regulating their body temperature, so you don't have to worry too much about them overheating. 

To prevent any arguments (always a must), an all-season solution, such as a 10.5 tog, may be the perfect compromise.

Types of Duvet

Not only are there a range of duvet togs to figure out, but there is also a range of fillings for your bedding. These are usually split into two categories:

  • Natural duvet fillings

  • Synthetic fill duvets

It is crucial to consider both the tog rating and the material when buying a duvet, as it's one way to ensure you never have another night of broken sleep. Synthetic fill duvets can offer a similar level of warmth to natural fillings. If you want one with the same tog rating, it may feel heavier due to the amount of filling required to reach that tog level.

Finding the ideal duvet tog is key to year-round comfort. Our expert guide simplifies the choice, helping you achieve the ideal balance of warmth and breathability for a truly restful night’s sleep, season after season.

What to Consider When Looking at Duvet Tog Ratings?

Duvet on Bed - Duvet Tog Guide

The temperature in your bedroom will fluctuate over the year, meaning you may need a thicker duvet in winter compared to summer. If you’re a hot sleeper looking for cooling bedding, then you may still need a lighter duvet even when the cold hits in December. 

Most sleep experts recommend finding a duvet with a tog rating between 4.5 and 7.5 for maximum breathability for summer. For winter, a tog rating of 11 to 13.5 will be ideal. If the temperature in your house does not change too much over the course of the year and you only want to invest in a single duvet, then a 10.5 tog is the perfect middle ground for your needs.

Your Mattress Matters: How Mattress Type Affects Duvet Tog Choice

What sort of mattress you sleep on can play a far bigger role in the degree of tog you should opt for than you might think. This is because particular mattresses retain heat better than others. 

Many memory foam mattresses hold heat far more than traditional mattress types, while pocket-sprung models and natural mattresses tend to be more flexible in their breathability.  If you are sleeping on a memory foam mattress, you should pick a slightly lighter tog than you otherwise would for a pocket-sprung mattress to stay cool while in bed.

Duvet Tog Choice for Kids: What Should You Consider?

If you’re looking to buy a new duvet for your child’s bed, it’s very important to consider the tog system to ensure they’re not too warm and get a good night’s sleep. Children are best suited to sleeping with a lightweight, single-size, and low-tog duvet. 

This is because their bodies have not yet mastered proper temperature regulation, and anything thicker could cause them to overheat or dehydrate at night.
