Die Zudecke Hungarian Goose Down duvet is a high-quality duvet filled with 90% goose down and 10% goose feather. It also has a premium 280 thread count cotton cover cambric that offers a gentle touch and adds the benefit of comfort and luxury. All Die Zudecke products are Nomite-Certified. This is issued by the EDFA and means that the fabric is so tightly woven that house dust mites cannot penetrate the fabric, making them suitable for sufferers of house dust mite allergies. All products also conform to the Oeko-Tex 100 Class 1 standard. This assures you that there are no harmful chemicals or substances in Die Zudecke duvets and pillows. Class 1 certification also means that they are suitable for babies and children. This bespoke duvet from Germany is made by expert tailors using traditional techniques and is one the most premium options available in luxury bedding. The wonderfully soft, fluffy clusters of Hungarian Goose Down trap large pockets of air, offering incredible softness, warmth, and minimal weight. The natural filling enables the body to breathe as it allows excess humidity created by the body during sleep to escape resulting in a refreshing night's sleep. This duvet also benefits from a cassette pocket construction, keeping the filling evenly distributed and eliminating any cold spots for a luxurious drape.
