How to Care for Your Children's Mattress

  1. Initial Setup: Once delivered, carefully remove the packaging and allow your kids mattress to air in a well-ventilated room for 4–24 hours to fully expand.
  2. Regular Rotation: To ensure even wear and longevity, rotate the mattress from head to foot every two weeks for the first three months, and then once a month thereafter.
  3. Use a Protector: Always use a waterproof mattress protector to shield the core from accidents, spills and accidents, which are common in children's rooms.
  4. Cleaning Instructions: If a spill occurs, spot clean only with a damp cloth and mild detergent. Avoid soaking the foam or springs.
  5. Vacuum Regularly: Lightly vacuum the surface of the mattress every time you change the bedsheets to remove dust and maintain a hypoallergenic environment.
