Duvet Tog ratings explained
What to consider
There are two important elements to consider when buying a new duvet – the filling and the tog rating. Decide between natural or synthetic fillings and check the tog rating to measure the warmth and thickness of the duvet. When buying a duvet you’ll want to know how warm it will keep you, especially in winter, so it’s important to find out its tog rating. You’ve probably seen it splashed across duvet packaging already, as it refers to how well the duvet is able to trap warm air around you and therefore keep you insulated at night. This ideally means choosing a Tog value of approx. 4 in Summer, changing to something between 6 and 11 in Spring and Autumn. Then if you want to stay warm in bed throughout the Winter, you should consider a duvet with a Tog value of 12 to 15.
“And remember, the weight of the duvet does not relate to its tog rating. Duvets filled with feathers or down naturally have better thermal properties than synthetic versions. This means you don’t need as much filling to achieve the same rating, often making them lighter.
