A pillow protector is a protective cover designed to encase a pillow, safeguarding it from dust, allergens, and spills. Made from various materials, such as cotton or polyester, these protectors can help extend the life of your pillow by preventing wear and tear. In addition to protection, many pillow protectors are waterproof, making them ideal for those with allergies or sensitivities. They are easy to clean and can often be machine washed, ensuring a hygienic sleeping environment. Using a pillow protector can enhance comfort and promote better sleep quality.
