A mattress protector is a removable bedding item that sits on top of, or encases, a mattress to protect it from spills, dirt, debris, allergens, and bacteria. It is a relatively thin layer of material that goes directly over a mattress, protecting it from liquid spills, dirt, and stains. Some mattress protectors also provide protection to the person sleeping on the mattress from allergens and irritants such as dust mites, bed bugs, mold, and dead skin. Mattress protectors come in different materials, including cotton, polyester, plush, bamboo, and synthetic materials like memory foam and spacer fabrics. There are also waterproof mattress protectors that keep the mattress clean by securing it from absorbing body excretions or other liquids resulting from spills. Mattress protectors can be in the form of a lightly quilted fitted sheet or a big zipper encasement that completely surrounds the mattress. Mattress protectors are recommended to protect the mattress from damage, which could ultimately work against the mattress warranty. They are also effective at shielding against contaminants including sweat, dirt and debris, dust mites and other allergens, bacteria, and bed bugs. Mattress protectors are a cost-effective way to protect your investment and make your bed more comfortable.
