Protect your mattress with the Tencel cotton mattress protector. Featuring a silky smooth design that has naturally low allergen, it's ideal all year round use. Tencel is made from the fibre of plantation wood pulp cellulose. Silky and incredibly soft, is far smoother than natural fibres like cotton and wool. It also boasts the most desirable properties of both man-made and natural fibres: soft as silk, strong as polyester, warm as wool, many more times as absorbent as cotton and naturally low allergen.
