When choosing a duvet, it is important to consider the tog rating, which indicates how warm the duvet is and how well it can trap warm air around you to keep you insulated at night. The higher the tog rating, the warmer the duvet, and the lower the tog rating, the cooler the duvet. Here are some general guidelines for choosing the right tog duvet:

• Summer: For summer, a lower tog rating is recommended, usually less than 7 tog. This is because higher temperatures mean you won’t need as much insulation to keep cool and get a good night’s sleep.

• Spring/Autumn: For the middle seasons, such as spring and autumn, a tog rating of 7-10.5 is recommended.

• Winter: For winter, a higher tog rating is ideal, usually 10.5 tog or above. A 13.5 tog duvet is suitable for colder winter nights, but a 15 tog duvet may be too warm for some people.

• All-season: If you want flexibility and versatility, an all-season duvet is a great choice. These consist of two separate duvets, usually a lightweight 4.5 tog for summer and a slightly higher tog option, say 9, for spring/autumn. You can then fasten them together using the button features to create a 13.5 tog duvet for winter.

It is also important to consider the filling of the duvet. Duvets filled with feathers or down naturally have better thermal properties than synthetic versions, meaning you don’t need as much filling to achieve the same rating, often making them lighter. If you are sensitive to heat or cold, you may need more than one duvet and switch at different times of the year. If you want just one duvet, a 10.5 tog duvet is considered a good all-rounder that can be used throughout the year.
