Tog Ratings (Summer vs Winter)
Understanding Duvet Tog Ratings: The term "TOG" stands for "Thermal Overall Grade"
Duvets have their own warmth rating, known as a tog rating. Tog measures how effectively a duvet retains heat rather than how thick or heavy it feels. This means a thick, fluffy duvet isn’t necessarily warmer than a thinner one — it’s the tog rating that tells you how much warmth it provides.
At Harry Corry, our duvets are available in a range of tog ratings to help you find the right level of comfort for the season and your sleeping preferences. Lower tog ratings are lighter and better suited to warmer weather, while higher tog ratings provide extra insulation for those colder nights.
Natural-filled duvets can often provide excellent warmth without needing as much filling as some synthetic alternatives, meaning they may feel lighter while still keeping you cosy.
Which Tog Should I Choose?
DID YOU KNOW?
The term tog refers to a measure of thermal insulation. Simply put, the higher the tog rating, the more effectively your duvet retains heat. A lower tog keeps things lighter and cooler, while a higher tog provides additional warmth when temperatures drop.
What Tog Is Suitable for Children?
Children generally require a lighter duvet than adults, as they can become warm more quickly during the night. The right tog will depend on their age, bedroom temperature and the time of year.
For younger children, a lightweight duvet can help keep them comfortable without becoming too warm, while slightly higher tog ratings may be suitable during colder months.
Important: Duvets are not recommended for babies under 12 months old. Always follow current safe-sleep guidance when choosing bedding for babies and young children.
Why Choose an All-Season Duvet?
An all-season duvet is a versatile choice if you want comfortable bedding throughout the year. These typically include two separate duvets with different tog ratings.
Use the lighter duvet during warmer months, switch to the warmer duvet when temperatures begin to fall, or fasten the two together for extra warmth on particularly cold winter nights.
It’s a practical way to adjust your bedding with the seasons without needing several separate duvets.
What size duvet do I need?
The size of your bed will usually dictate the size of your duvet, with single through to super king size duvets made to fit the standard dimensions of beds with the same name. Buy your bedding in the same size as your bed and your duvets will cover you comfortably, but if you like extra coverage try buying the next size up (e.g. a single bed with a double duvet).
Fillings (Natural vs Synthetic)
Should I Choose a Natural or Synthetic Duvet Filling?
Choosing between a natural or synthetic duvet filling often comes down to personal preference, budget and the type of feel you prefer when you sleep.
Synthetic duvets are a practical and versatile choice. They’re generally easy to care for and available in a variety of tog ratings, making it simple to find an option for every season. Many synthetic duvets are also designed with hypoallergenic properties, which can make them a good choice for allergy sufferers.
Natural-filled duvets, such as feather and down, offer a luxurious and cosy feel. Natural fillings are excellent insulators and can provide plenty of warmth while remaining breathable. Depending on the filling and construction, they can also have a fuller or weightier feel.
If you prefer a lightweight, easy-care duvet, synthetic may be your ideal choice. If you love that traditional, luxurious and cosy feeling, a natural filling could be just what you're looking for.
How Do Duvet Cover Fabrics Differ?
Although you'll usually protect your duvet with a separate duvet cover, the fabric used for the duvet's outer casing can still make a difference to how it feels and performs.
Different materials offer different benefits when it comes to softness, breathability, durability, temperature regulation and ease of care. Here's a quick guide to some of the most common options.
Cotton
Cotton is naturally breathable, soft and durable, making it a comfortable choice for your bedding. Its fresh, crisp feel can help create a comfortable sleeping environment, while its durability makes it well suited to everyday use.
Polyester Microfibre
Polyester microfibre is soft, lightweight and easy to care for. It's a practical option for busy households and typically dries more quickly than cotton, while still providing a comfortable and cosy feel.
Polycotton
Polycotton combines the softness and breathability of cotton with the durability and easy-care qualities of polyester. This makes it a great all-round option for those looking for a balance between comfort, practicality and longevity.
Bamboo
Bamboo fabrics are known for their wonderfully soft and breathable feel. They can also offer excellent moisture management and temperature regulation, helping you stay comfortable throughout the night.
How do cover fabrics differ?
While your duvet is likely to be encased in a separate duvet cover, choosing the right cover fabric is still important, when it comes to properties such as breathability, temperature regulation, washability and softness.
A cotton duvet casing is durable, easy to care for, naturally breathable and has a crisp finish that looks fresh and inviting.
This cover is made from 100% polyester and is durable, soft, easy to care for and faster to dry than cotton duvets.
Made by blending durable polyester and soft cotton in a variety of ratios, this easy-care option balances comfort with longevity.
Bamboo is soft, breathable and naturally anti-bacterial, which can help minimise skin irritation and allergies.
Anti-Allergy Duvets
These duvets have been finished with an Aegis Microbe Shield Treatment, which provides dust mite and allergen protection, up to 10 machine washes.

An all-seasons duvet typically combines two separate duvets of different tog ratings. They can be used individually during warmer weather or fastened together when you need additional warmth, making them a versatile choice throughout the year.
Which duvet is best for hot sleepers?
If you tend to get warm during the night, consider a lightweight duvet with a lower tog rating. A 4.5 tog duvet can be a good option for warmer weather, while breathable fillings can also help provide a more comfortable night's sleep.
Which duvet is best for winter?
For colder nights, a higher tog duvet can provide additional warmth. A 10.5 or 13.5 tog duvet may be suitable, depending on your bedroom temperature and personal preference.
What duvet filling should I choose?
Duvets are available with a range of fillings, including hollowfibre, microfibre and natural fillings such as feather and down. Synthetic fillings can be a practical, easy-care choice, while natural fillings are often valued for their warmth and breathability.
Are synthetic duvets easy to care for?
Many synthetic duvets are easy to care for and may be machine washable, making them a convenient choice for everyday use. Always check the individual product's care instructions before washing or drying your duvet.
How often should I replace my duvet?
There isn't a fixed replacement schedule, but you should consider replacing your duvet when it becomes flat, lumpy, damaged or no longer provides the comfort and warmth you need. Following the care instructions can help extend the life of your duvet.
How do I choose the right duvet for me?
Consider your preferred sleeping temperature, the time of year, your bed size and your preferred duvet filling. If you're unsure, an all-seasons duvet can offer flexibility throughout the year, while a lower or higher tog duvet can be chosen to suit your usual sleeping environment.
