Mattress protectors are removable covers designed to shield mattresses from spills, stains, dust, allergens, and general wear, thereby extending their lifespan. Typically made from materials like cotton, polyester, or waterproof fabrics with a protective layer, they are available in fitted, zippered, or elastic strap styles for secure placement. Some mattress protectors also feature hypoallergenic and breathable properties to enhance comfort while maintaining hygiene. Commonly used in homes, hotels, and healthcare facilities, they help preserve mattress quality and ensure a cleaner, healthier sleeping environment.
