9.0 Tog Goose Down Duvet (Spring/Autumn)

Spring/Autumn duvets are our most popular duvets. They are exceptionally versatile medium-warm duvets, a godsend for people looking for a duvet they can use throughout most of the year. It may indeed also be suitable in the colder months for those whose local climate doesn’t experience drastic temperature changes across seasons. If you live somewhere with cold winters and hot summers, we recommend swapping out one of these duvets with a warmer one in the colder months and a lighter one for summertime. These duvets are sewn with medium baffles. This inhibits some ventilation through the seams and allows for greater down expansion, leading to better insulation.

Available in all sizes from single to super king, Autumn/Spring duvets are the ideal space-saving comforter. All our duvets are premium products with natural filling of at least 90% down and are produced in workshops which exercise extensive quality control and maintain high standards of excellence.

What makes a good 9.0 tog goose down duvet?

Medium Boxes

The size of the ‘boxes’ which make up a down duvet is a good visual indicator of its relative warmth. The more filling within one of these quilted squares (down chambers), the more efficient the insulation it provides. Spring/Autumn duvets will have a greater number of boxes than a winter duvet and fewer than a summer one. In most cases a 135 cm x 200 cm spring/autumn duvet will have 48 boxes arranged in a 6 x 8 grid.


Ventilation refers to the air permeability of a down duvet. Spring/Autumn duvets are sewn with baffles, increasing their insulating power while reducing airflow somewhat. This inhibits ventilation a bit, meaning the duvet retains a greater amount of the warmth of the person sleeping beneath it.

Tog Rating

We use tog rating as an easy-to-understand measurement of insulation. A higher tog means that a duvet is suitable for colder environments. A tog rating of 9.0 indicates a medium, spring/autumn duvet. Further information can be found on our page about the tog system.

Down Quality

European Standard EN 12934 regulates the categorisation and naming of the filling material in bedding based on the proportion of new down and the types of poultry used. Only Class 1 down fillings may bear the quality rating “new”. All products on Downduvet.co.uk are filled with the best, Class 1 filling.


Experience shows that duvets with fabric of Ne 30 or higher are suitable for use by people with dust mite allergies. Premium down comforters have high-quality covers ranging from Ne 40 to Ne 155. On this website, you can see the Ne of each duvet under its product details. Additional protection is provided by duvets with the NOMITE label, which we recommend for allergy sufferers.
