Choosing the Right Tog

All duvets at Downduvet.co.uk are classified with the tog system. The tog-value of a down duvet is equal to ten times the temperature difference between its two faces (in degrees Celsius) when the flow of heat across it is equal to one watt per m². The higher the rating, the warmer the duvet will be. Choosing the right tog is important, because if you’re too hot or too cold in bed, you won’t get a good night’s sleep. See which tog is best suited to your needs.

Thermal classes

The Summer duvet (4.5 tog):
A box stitched, very light duvet, suitable for warm bedrooms.

The SummerPlus duvet (6.0 tog):
A box stitched, light duvet. Suitable for a longer period than just summer.

The Spring/Autumn duvet (9.0 tog):
A medium-warm duvet suitable for a lot of people during most of the year. It can be box stitched (Otto Keller and some Kauffmann) or baffle box like the other duvets in this thermal class.

The Winter duvet (12.0 tog):
A warm duvet for the cold bedroom or for those who easily feel a chill. The winter duvet is a standard baffle box, stitched one with bands between 2 and 6 centimetres that gives the duvet an optimal insulation value.

The WinterPlus duvet (15.0 tog):
For those who want the warmest of duvets, the WinterPlus duvet is uniquely suitable. We seldom recommend these duvets though, as in modern houses with central heating this duvet will be too warm, unless you specially require a lot of extra warmth.

At our compare duvets page, you can compare by duvet price, size, season, brand, fill power, ticking and down.

There can be slight differences between the various brands when it comes to tog, so please read our guide to differences in tog to find out more.
