A bed protector is a protective covering designed to shield a mattress from spills, stains, and allergens. It acts as a barrier against dust mites, bacteria, and other irritants, helping to maintain a clean and healthy sleeping environment. Bed protectors come in various materials, including cotton, polyester, and vinyl, and can be easily removed for washing. In addition to protecting the mattress, bed protectors can enhance comfort by adding a soft layer. They are available in different sizes to fit various mattress dimensions, such as twin, full, queen, and king. Using a bed protector can extend the life of a mattress and improve overall sleep quality.
