What makes a good 4.5 tog goose down duvet?

Small 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. Therefore summer duvets will have a greater number of boxes than a winter equivalent. The boxes will in turn be smaller. In most cases a 135 cm x 200 cm summer duvet will have 80 boxes arranged in an 8 x 10 grid.


Ventilation refers to the air permeability of a down duvet. Summer down duvets are sewn without baffles, allowing air to ventilate easily through the seams, thereby preventing overheating. It also regulates moisture, keeping the person underneath both cool and dry.

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 4.5 indicates a light, summery down 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.
