A memory foam mattress offers unparalleled comfort and support for a restful night's sleep.

To maintain its quality and extend its lifespan, regular cleaning is essential. However, cleaning a memory foam mattress requires special care to avoid damaging its unique structure, it's slightly different from cleaning a usual mattress.

In this comprehensive blog post, we'll walk you through step-by-step instructions on how to clean and maintain your memory foam mattress effectively.

Understanding Memory Foam

  1. Composition: Memory foam is made of a viscoelastic polyurethane material that responds to body heat and pressure. It moulds to your body shape, providing personalized comfort and support.

  2. Sensitivity: Memory foam is sensitive to moisture and can retain liquids, making it prone to mould, mildew, and odour if not cleaned properly. Therefore, it's crucial to use appropriate cleaning techniques.

Regular Maintenance

  1. Use a Mattress Protector: Prevent stains, spills, and debris from reaching your memory foam mattress by using a waterproof, breathable mattress protector. This acts as a barrier, preserving the cleanliness and longevity of your mattress.

  2. Rotate and Flip: Rotate your mattress 180 degrees every three to six months to distribute the wear evenly. Flipping may not be necessary for one-sided memory foam mattresses, but check the manufacturer's guidelines to be sure.

General Cleaning Guidelines

  1. Vacuum Regularly: Use a vacuum cleaner with a soft brush attachment to remove dust, allergens, and surface debris from your memory foam mattress. Vacuuming should be done at least once a month to keep it clean and fresh.

  2. Spot Cleaning: Attend to spills and stains promptly. Blot the affected area with a clean, absorbent cloth or paper towel to absorb as much liquid as possible. Avoid rubbing, as it can push the stain deeper into the foam.

Deep Cleaning Foam Mattresses

  • Remove Odours: To eliminate bad smells from your memory foam mattress, sprinkle baking soda over the surface and let it sit for several hours or overnight. Vacuum the mattress thoroughly to remove the baking soda residue.

Stain Removal From Memory Foam Mattresses

Water and Mild Detergent: For fresh stains, dilute a mild liquid detergent in water and gently dab the stained area with a clean cloth. Blot with a damp cloth to remove the detergent residue. Allow the mattress to air dry completely before covering it.

Enzyme Cleaner: For tougher stains, consider using an enzyme-based cleaner. Gently work it into the stain, and allow it to sit for the recommended time. Be wary that you are cleaning memory foam so oversaturation can become a big problem. Blot and rinse with a damp cloth, then air dry.

Maintaining Shape and Support

  1. Avoid Jumping or Sitting on Edges: Memory foam mattresses are designed to distribute weight evenly. Excessive pressure on the edges can lead to sagging or loss of shape. Avoid jumping or sitting on the edges to maintain its structural integrity.

  2. Rotate Regularly: As mentioned earlier, rotating your memory foam mattress helps prevent uneven wear and sagging. It ensures that different areas of the mattress receive equal pressure and support.


Proper cleaning and maintenance are crucial for preserving the comfort, cleanliness, and lifespan of your memory foam mattress.

Regular vacuuming, spot cleaning, and using a mattress protector are essential steps in keeping it fresh.

When necessary, deep clean the mattress using suitable techniques and products, ensuring proper drying afterward. By following these guidelines, you'll enjoy a clean, comfortable memory foam mattress that provides years of restful sleep.
