Tog Duvets Explained
There is a lot to consider when choosing the ideal duvet. There are tog ratings, fillings and size to take into account.
A tog rating is a measure of thermal resistance. The higher the tog, the more warm the duvet. The thickness of a duvet doesn't necessarily correspond to warmth. Different fillings regulate the heat in different ways.
1. What is a tog?
It is essential to have a comfortable bed for an enjoyable night's sleep. However, you should select the appropriate duvet in accordance with your personal preferences and the season. Many duvets come with an indicator label that indicates the tog rating. But what does it mean?
The tog is an overall thermal grade that allows you to understand how warm or cold the duvet will be and is not related to the weight (which is determined by the filling). A higher tog means that the duvet is warmer. 1 is the most light and cool, while 15 is the most warm.
It is important to choose the right tog as too much heat can cause overheating and wake in the middle of the night, while insufficient heat can make you feel cold through the night. A warm, high-tog duvet is ideal for summer while a light low-tog duvet is great for winter.
Tog ratings are generally set by the Shirley Institute in Manchester, and they work in an ascending order, with the lowest rating of 3 and the highest tog rating being 15. The higher the rating for tog the more warm the duvet.
However, a tog doesn't necessarily mean thickness since certain duvets might have the same tog rating, however, they may have different sizes and types of material. For instance, natural-fibre 7.5 tog duvets are typically heavier than synthetic ones however this doesn't necessarily mean that they're more or less warm, as the breathability of a duvet has much to do with the material a duvet has been filled with. Synthetic duvets are made up of hollow or microfibers to keep warm and natural-fibres are stuffed with softer materials like feathers and cotton.
2. What is the difference between natural and synthetic duvets?
Duvets are almost always evaluated by their tog rating which is an indicator of warmth and not thickness. The higher the rating, the more comfortable it is. It's important to keep in mind that a duvet's temperature is only one aspect. The choice of natural or synthetic fillings is also vital.
Synthetic duvets are constructed from man-made materials that mimic the feel and look of natural fibres. This is a great choice for people who are allergic or overheated at night. They're also generally less expensive than their natural counterparts, however, they do not breathe as well, which means that your skin won't be able to release heat as easily.
