Some covers are designed to fit over the entire mattress, while others simply cover the top using corner straps to stay in place.Protection From DirtA mattress cover serves as a buffer between the mattress and bedding, which helps minimize staining and soiling of the mattress itself. Some mattress warranties are voided if your mattress is soiled.Protection From AllergensSome mattress covers are made specifically to repel dust mites, spores and reduce allergens. This type covers the entire mattress, is somewhat more expensive and is a must-have for anyone suffering from allergies.Protection From FluidsTo prevent spills or accidents from damaging your mattress, protect your mattress with a cover specifically designed for fluids.
