How warm is a 15 tog duvet?

A 15 tog duvet is an extra-warm winter option that provides more thermal insulation than 13.5 tog but less than 16 tog. It may suit colder bedrooms, less well-insulated homes or sleepers who have previously found 13.5 tog insufficient.

If you are comparing the warmest winter options, read our Highest Tog Duvet UK guide for a closer comparison of 13.5, 15 and 16 tog.

Can a 15 tog duvet be too warm?

Yes. In a consistently warm or well-insulated bedroom, 15 tog may provide more insulation than you need, particularly outside the coldest part of winter. If you prefer changing duvet warmth as temperatures rise and fall, explore our all-season duvet options or compare lower tog ratings in our duvet collection.

Who tends to choose 15 tog?

15 tog is often chosen by sleepers who naturally feel cold at night, people using colder or draughtier bedrooms, or anyone who has previously found 13.5 tog insufficient. If you want slightly less insulation, compare our 13.5 tog duvets. If you prefer even more insulation, view our 16 tog duvet, which is currently the highest-insulation option in the Stoftly range.

Does duvet size change the tog rating?

No. A 15 tog duvet has the same tog rating whether you choose Single, Double, King or Super King. Tog measures thermal insulation, while duvet size determines how the duvet fits your bed. Choose your size primarily according to your bed dimensions rather than expecting a larger duvet to have a higher tog rating.
