Shopping around to buy a natural mattress protector in Canada? This unique Merino wool mattress protector, has been specially milled by a chemical-free European process to make it completely machine washable (and dry-able) without shrinking.
Standard wool covers can only be dry cleaned, or hand washed. St Dormeir mattress covers have all the convenience of polyester fills, with all the advantages of natural virgin wool. Pure Merino wool quilted in the cotton cover, regulates body temperature and humidity (keeping you cool in the summer, and cozy in the winter) while preventing the growth of bacteria, mold and mildew. These qualities are essential in helping you fall asleep faster and also stay asleep longer.
The St Dormeir mattress protector is made with 100% Chemical free cotton terry 
This cotton is woven in a jersey knit and is used as the skirt that goes around the sides of the protector. It has an elastic band around the bottom edge for a secure fit.
