The mattress is, without a doubt, the dirtiest object we have close contact with. Men, women and children spend one third of their lives sleeping on mattresses that are extremely soiled and as such, potentially dangerous to their health. This applies equally to a mattress that is only a few months old as it does to a mattress several years old.

It is erroneous to believe that a sheet will protect against this kind of dirt, consisting of micro particles (1 - 20 microns). A bed sheet protects against these particles about as much as a fishing net would protect against sand. With every movement of the body in bed, dust and mite excrement are churned up. The mattress acts as a bellows, blowing dirt into mouth, nose, eyes and onto the skin.
