How to Care for Your Double Mattress Topper

  1. Unpack and Air: Your topper arrives vacuum-packed. Carefully unwrap it and allow it to expand in a well-ventilated room for 24-48 hours.
  2. Regular Rotation: To ensure even wear, rotate your double mattress topper 180 degrees every few weeks. Do not flip it if it is a single-sided design.
  3. Spot Cleaning: If spills occur, spot clean the foam with a damp cloth and mild detergent. Do not soak the foam or put it in a washing machine.
  4. Freshness Check: Use a breathable mattress protector over your topper to keep it hygienic and protected from moisture.
  5. Airing Out: Occasionally strip the bed and allow the topper to "breathe" for a few hours to help moisture evaporate and maintain foam integrity.
