Pillow top mattresses have a soft layer stitched on top of the mattress. These beds offer prime comfort, but they can be costly. A pillow top mattress cover will mimic the softness of a pillow top mattress at a much lower cost and will also serve to protect the mattress from wear. Like bed sheets, you should clean a pillow top mattress cover regularly as it can be prone to collecting sweat and dust mites.
Wash a pillow top mattress cover made of down feathers or wool in warm water. Use a large washing machine to prevent the cover from tearing. If necessary, take the cover to a laundromat to secure a large enough machine.
Take a pillow top mattress cover made of memory foam outside, and shake it to remove dust. Place a protective covering on the floor, such as a sheet, and lay the cover on top of it. Use the handheld attachment of a vacuum cleaner to deep clean.
