Memory foam mattress toppers conform to the human shape because of their cell structure. A 5 to 7.5 cm (2 to 3 inch) topper on a firm mattress reduces pressure points and can prevent morning aches and pains. Memory foam holds water like a giant sponge, so washing it can be tricky. Memory foam should never be put in the washing machine and only some types can be dry cleaned.

  1. 1

    Pre-treat stains, either with a product recommended by your topper's manufacturer, or with a mild household linen cleaner. Use a damp sponge to blot the stain. Remove as much of the stain as possible with a gentle circular motion. Let it dry thoroughly.

  2. 2

    Vacuum the topper. Use a hand-held vacuum over the entire surface on both sides.

  3. 3

    Put a single bed-sized mattress topper in the bath if you have a detachable hand-held shower head. Larger pieces should be cleaned outside on a plastic sheet or other clean surface where they can be reached by a hose.

  4. 4

    Fill a spray bottle with one part mild washing powder to two parts warm water. Spray the topper thoroughly, covering all surfaces. Let the detergent work for about half an hour.

  5. 5

    Rinse the surface without saturating the material. Gently squeeze out extra moisture but don't twist the foam.

  6. 6

    Let the foam dry for several days. Keep it away from direct sunlight and lay it flat so it doesn't lose its shape. A hair dryer can be used on smaller pieces of foam.

Tips and warnings

  • Check the washing instructions. You may be able to have it dry cleaned.
  • Buy a mattress cover to protect the foam.
  • Do not put memory foam in the washing machine or tumble dryer. This can cause it to shred.
