Product Care

Mattresses:

Rest easy with the fact that your Ashley-Sleep® mattress doesn’t require much care and maintenance. For starters, all Ashley-Sleep mattresses are designed to be no flip—now isn’t that a relief!

How to Care for Your Mattress:

  1. To help keep your Ashley-Sleep mattress clean, a thin mattress protector is recommended so it breathes to allow airflow and heat dissipation. Ashley-Sleep does not recommend you use a quilted mattress pad as it will change the feel of the mattress you selected at the store. It may also trap heat that needs to escape.
  2. Don’t use dry cleaning fluid of any type on your mattress. These chemicals could damage some of the comfort and upholstery materials.
  3. Vacuuming is the only recommended cleaning method. If you must clean a stain, use mild soap with cold water and apply lightly, allowing the mattress time to fully air dry.
  4. Please remind the kids not to jump on their Ashley-Sleep mattress, as doing so can break down the inner construction and materials.
