Moisturize your skin, particularly your hands with anti-static lotion available at electronics stores. Static shock can occur when synthetic materials, such as polyester come into contact with dry human skin.
Wear natural fiber clothing and shoes made of materials, such as cotton, wool or leather, or arrange a cotton or wool blanket between yourself and the couch when lounging. Natural fibers do not conduct electrical charges as well as synthetic fibers do.
Spray an anti-static product on your couch or rub the couch down with a fabric softener sheet, as a temporary solution. Test the spray on an inconspicuous area of your couch to make sure there is no discoloration before using it on visible cushions and pillows.
Raise the humidity in your home to 50 percent relative humidity, using a humidifier. Keep plants in the room that the couch is in to increase the humidity because plants take in water and release it into the air as water vapor, adding moisture. Moist, humid air decreases the conductivity of electrical charges, reducing static shock.
