Protection Against Spills and Stains: It acts as a barrier against liquid spills, sweat, and bodily fluids, preventing them from seeping into the mattress. Allergen Defense: A mattress protector can help protect against allergens such as dust mites, pet dander, and pollen, which can accumulate in mattresses over time. Increased Mattress Longevity: By shielding the mattress from physical damage and contaminants, a protector can extend the life of the mattress. Ease of Cleaning: Most mattress protectors are machine washable, making them easier to clean than a mattress itself. Comfort: Some mattress protectors are designed to add an extra layer of comfort, with features like quilted padding or cooling materials. Waterproof Options: Many mattress protectors are waterproof, which is particularly beneficial for households with children or pets.
