The quality and composition of Duvets and Pillows affects how well one sleeps.
Feather & White Duck Down is warm and luxurious but can be problematic for asthmatics.
100% Wild Silk is light in weight, breathes, is very supple and constantly equalizes temperature. It is inhospitable to dust mites, as it does not retain water, making it naturally hypoallergenic.
Soya Duvet is 100% natural. It is a viable alternative to Micro Fibre, as it breathes with your skin, and adapts to body temperature, while having the feeling of weight.
The most reasonably priced alternative, Micro Fibre duvets are available in different weights for changing seasons.
