The ERWIN M. Perfekta is a white pillow designed for those who appreciate a classic, supportive sleep experience. It features a filling of 85% new white goose feathers and 15% new white goose down, categorized as Class 1 filling, which provides a balanced blend of loft and stability. To ensure the filling stays evenly distributed and doesn't shift during the night, the pillow is constructed with a Downpass quilted design throughout. Its 60 x 80 cm frame is encased in a 100% cotton fine twill cover that is specifically engineered to be feather-proof, preventing quills from poking through. For added peace of mind, the materials are OEKO-TEX® STANDARD 100 certified and have passed the EN ISO 12952-1 cigarette annealing test for safety. You can maintain the pillow by washing it on a gentle cycle up to 60 °C and tumble drying on a low setting, though you should avoid using chlorine or bleach.
