Mattress protectors are bedding accessories designed to shield mattresses from spills, stains, allergens, and general wear, thereby extending their lifespan. Commonly used in hotels, resorts, and homes, they are placed directly over the mattress and beneath the fitted sheet. Made from materials like cotton, polyester, or waterproof fabrics with breathable layers, mattress protectors provide comfort while preventing dust mites and bacteria buildup. Available in fitted, zippered, or elastic strap styles, many protectors are machine-washable and designed to maintain mattress hygiene and freshness, ensuring a clean and comfortable sleeping environment for guests.
