Prolonged exposure to direct sunlight can cause the colors to fade and the fabric to weaken. To protect your sofa fabric from the damaging effects of UV rays, consider placing your sofa away from windows or using curtains and blinds to filter the sunlight. If possible, rotate your sofa periodically to ensure even fading and wear.
