In the classical Sarder mattress, there is a layer of sheep wool added on one side and cotton layer on the other side between polyurethane foam and fabric. Natural sheep wool preserves body temperature and at the same time lets the mattress breatheespecially comfortable during winter time. Cotton on the other side adds even more breathing properties and keeps the body dry during very warm nights. Mattress cover is made of quilted fabric with 70% cotton content.
