The Erwin M. Perfekta is a white duvet designed for a comfortable night's sleep, measuring 135 x 200 cm. It features a balanced filling of 50% semi-white new goose feathers and 50% semi-white new goose down, categorized as Class 1 filling for a reliable level of warmth. To ensure the filling stays evenly distributed and doesn't shift during use, the duvet is constructed with a cassette quilt design that is stitched throughout. The outer cover is made from 100% cotton fine ticking, which is specifically engineered to be feather-proof. For peace of mind regarding safety and quality, this model carries the Downpass seal and is OEKO-TEX® STANDARD 100 certified, having also passed the EN ISO 12952-1 cigarette glow test. Maintaining the duvet is straightforward, as it can be washed on a gentle cycle at temperatures up to 60 °C and tumble dried on a gentle setting. To preserve the fabric and filling, you should avoid using chlorine or bleach, though gentle cleaning with perchlorethylene is an option.
