A 10.5 tog duvet is a medium-warmth duvet, the middle of the standard UK range of 1 to 15 tog. It's often called an all-season duvet, because it suits most of the year in a centrally heated home. It's warm enough for winter in a heated bedroom and too warm for most summer nights.
Here's how 10.5 tog compares with the weights either side:
| Tog | Warmth | Best for |
|---|---|---|
| 7.5 | Light all-season | Spring, autumn, warm sleepers |
| 10.5 | Medium, all-season | Most of the year in a heated home |
| 13.5 | Winter weight | Winter, rooms that cool overnight |
Is 10.5 tog warm enough for winter?
Yes, 10.5 tog is warm enough for winter in a bedroom with central heating. If your heating goes off at night and the room is cold by morning, it won't be enough and a 13.5 tog duvet is the better pick. Adding a blanket on top is a cheap way to stretch 10.5 tog through the coldest weeks.
For a full comparison of winter weights, see our guide to the best winter duvet tog, which covers 10.5, 13.5 and 15 tog.
Is 10.5 tog too warm for summer?
Yes, 10.5 tog is too warm for most UK summers. On warm nights you'll want 4.5 tog, and in a heatwave 1 or 2.5 tog. If your bedroom stays cool in summer, for example a north-facing room or a basement flat, some people manage with 10.5 tog all year, but most swap to a lighter duvet from about May to September.
What is a 13.5 tog duvet?
A 13.5 tog duvet is a winter-weight duvet, one step warmer than 10.5 tog. It's made for the colder months and bedrooms that cool down overnight. Only 15 tog is warmer. Most UK households use 13.5 tog from about November to February and a lighter duvet for the rest of the year.
Our 10.5 tog duvet comes in single, double, king and super king, from £19.49 for a single. The same microfibre duvet is available in 13.5 and 15 tog if you'd rather have a dedicated winter weight. For every season in one chart, see our duvet tog guide.
