Examine the ingredient label on any area rugs near the couch to ensure they are made only of all natural materials, such as cotton or silk, and not manufactured fibers, such as nylon or polyester. Natural fibers do not generate static electricity as much as man-made fibers do.
Place a humidifier inside the room where the couch is located, and fill the internal water tank with distilled water up to the designated fill line. Plug the electrical cord into an outlet and set the humidity level to between 40 and 50 percent. Let the humidifier run during the daytime hours when the couch is in use. Adding moisture to the surrounding air prevents the buildup of electrical charges.
Open a spray bottle of anti-static solution and spray a light layer over all surfaces of the couch. Test a small area on the back of the couch first to ensure no color change occurs. You can also spray the anti-static substance on the carpeting in the room to further decrease static electricity.
