Down duvet, comprising two layers of fleece inserted between down-filled layers

摘要

The duvet is assembled of three layers filled with downs and divided by crosswise arranged seams into a multitude of squares (1) in order to avoid the contents to slip into an irregular position. Two layers of fleece are inserted horizontally between the down layers, creating air-filled spaces acting as barriers against a loss of heat. The down layers and the fleece layers are joined at the outer edges (2) with a common seam.
