These chemicals could damage some of the comfort and upholstery materials.|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.|Please remind the kids not to jump on their Ashley-Sleep mattress as doing so can break down the inner construction and materials.
