Was used once. Decided to go with feather comforters. From manufacturer: A duvet in soft, dobby woven cotton, filled with light and airy mulberry silk for a luxurious feel. A light warm duvet that is perfect for warmer seasons and if you often feel warm during the night. A good choice for allergy sufferers as the silk is resistant to dust mites and dirt. The silk filling is temperature regulating, keeping you warm when it's cold, and cool when it's hot. It also breathes and circulates air so that moisture evaporates, giving you a good sleep environment. It's easy to freshen up your silk duvet. Simply air it a couple of times a year to allow the silk to breathe, revitalise and regain its fluffiness, Materials and care Fabric: 100% cotton Filling: 100% silk - mulberry, Machine wash, max 30°C, mild process.
