Mattress covers and pads are added protection that are placed on top of your existing mattress, to help protect you from allergens and irritants, such as dust mites, bed bugs, mold, and even dead skin. A mattress topper can go on top of your mattress for an added layer of softness, and protection from leaks and spills, while a mattress pad wraps around the entire mattress for a snug fit. The top of the line is a memory foam mattress topper, which can add another layer of comfort to your mattress, and can contour to your body, so you can get a more restful night's sleep. Zoro also has a super selection of linens and bedding, sheets and pillow cases, and bedspreads and comforters.
