Understand Your Mattress Cover

Investing in a mattress cover for your bed is a very wise decision. Using one can help prolong your bed's life and cleanliness and make for a better sleeping experience. When you have a mattress protector, it is slipped over any mattress toppers and creates a barrier to deter bedbugs, dust mites, mold, dandruff, and allergens. Any sheets, blankets, or comforters are placed on top of a mattress protector.

Leaving a mattress unprotected and without a cover makes it vulnerable to developing yellowing, stains, mold growth, and foul odors. The slightest amount of protection for a mattress would require placing a fitted or strapped sheet that is quilted or flat on top of the bed. However, a full-service cover with or without a zipper is optimal.  Today's modern mattress covers available for use include and is not limited to the following types.

  • A plastic pad with or without a fabric cover
  • A breathable fitted cover with a waterproof lining underneath
  • A zip-up cover that completely encases the mattress

No matter what type of mattress cover you choose, you should routinely remove it from the mattress for cleaning. Even the quality, durable mattress protectors can eventually succumb to stains, mildew, mold, and allergens if left unwashed for long periods of time. While you are laundering your mattress cover, make time to vacuum, spritz, and wipe down your mattress and allow it to air dry before returning a clean and dry cover to the mattress.

Which Type Of  Cover Is Best

If you feel that you don't need a lot of protection, a simple, loosely fitting pad or sheet on top of a mattress is sufficient. However, in some instances, you may want to cover more of the surface area of your bed. When bedbugs or dust mites are a problem, it is best to use a zippered case that fully encloses a mattress. A waterproof cover or protective with an underlayer that resists moisture can prevent nighttime accidents or spills from coming in contact with a mattress. 

Over time, even with a mattress cover or protector, a bed can display yellow stains, hold onto allergens, or become a problem. Keep an eye on your mattress and your health by changing the type of cover you have for your mattress and removing any cover you are currently using to wash it as needed. Take time to disinfect your mattress and any covers to reduce allergy triggers and close contact with mildew, mold, and unwanted elements. Don't forget to change your sheets and use clean linens on top of a cover for a more comfortable, healthy bed.

Dust mites and moisture are two of the biggest threats to your mattress. Sweating because of a lack of breathable linens or mattress covers, nighttime incontinence, and accidents with drinks lead to stains and deep-set mold if left unchecked. Because humans shed their skin cells and hair frequently, dust mites naturally congregate in and on the surface of mattresses and bedding. Mattress covers are often made from polyester, urethane, cotton, down, and have a layer of waterproof material.

When your mattress protector has outlived its usefulness, it's time to give it the old heave-ho.
