What is down?

Waterfowl such as geese have both feathers and down. The fine, highly branched down with a short quill forms many small air pockets that provide excellent thermal insulation. Their three-dimensional structure gives them high loft: they expand quickly after being compressed. These properties allow geese to protect themselves from cold, heat, and wet conditions – advantages that are also used for down duvets.

Selecting Down for Down Duvets

billerbeck subjects the down used to rigorous quality testing. The quillless, fluffy down is ideal for warm yet pleasantly light duvets.

"Guaranteed traceable certified goose down and feathers"

The down duvet – perfect for all seasons

Down not only has warming properties, but also temperature-regulating properties, creating an excellent microclimate in your bed. Thanks to duvets in various warmth levels, you can sleep in down all year round.

To prevent the individual down feathers in the down duvets from shifting and to prevent cold spots, inner baffles are sewn into the duvet in a square pattern, forming a cassette shape. This is why down duvets are often referred to as cassette duvets.

The height of the inner baffles (2, 4, 6, or 10 cm) determines the filling quantity of the individual cassettes, which affects the different warmth levels. This means: the higher the inner baffle, the higher the warmth level, and the warmer the duvet. A higher individual cassette with a higher down content creates a better warming cushion and ensures good airflow.
