Gingerlily's pure silk filled mattress protector, when used with one of its silk filled comforters and pillows, provides the ultimate cocoon to help you achieve the perfect night's sleep. Made using the finest quality long strand mulberry silk, they are naturally hypoallergenic and the only natural bedding choice for those with sensitive skin and allergies. Silk, a breathable fibre, is a natural heat conductor that will help keep your body at consistent temperature throughout the night, ensuring you stay warm in winter and beautifully cool in summer.
