Read the care labels on your couch, throw blankets and accent pillows to find out the type of material they are made of. This can indicate whether the couch or a different source with which it is coming into contact is causing the static. Natural fibers such as cotton, leather and wool gain positive charges and synthetic materials including polyester, fleece and vinyl gain negative charges.
Substitute throw blankets and accent pillows made of materials that gain negative electrons with replacements made of natural fibers that gain positive charges on positively charged couches. Substitute accents made of natural fibers with those made of synthetic fibers on couches composed of synthetic fibers. Consider changing clothing before using your couch with regard to the same rule. Combining materials that have opposing charges causes static when the charges transfer between materials.
Vacuum and dust your couch and floor regularly and use a lint roller on clothing to remove pet dander, hair, dust and dry human skin flakes. Such materials are inclined to transfer negatively charged electrons to couch materials with a propensity to gain negative charges, causing static.
Apply lotion to your skin to prevent it from becoming dry, as dry skin promotes static electricity. You can rub anti-static hand lotion on your hands to decrease static when touching certain couch surfaces, such as those made of polyester.
Rub a dryer sheet or spray an anti-static spray on couch cushions, accessories and clothing to decrease static. Dryer sheets and anti-static sprays contain fabric softener that reduces the buildup of static.
Increase the relative humidity level in the room in which your couch is located to 50 percent, using a room humidifier, vaporizer, air purifier or ionizer. You can also place plants on end tables near the couch, as they give off moisture, escalating the humidity level.
