Maintenance of genuine leather sofas is relatively more troublesome. First of all, furniture must be placed away from high temperatures. Excessive temperature can cause changes in the appearance of the leather, leading to adhesion. Therefore, furniture should not be placed near stoves or radiators, and should not be exposed to direct sunlight near windows either. Similarly, placing genuine leather sofas in rooms with low temperatures is also unacceptable. Low temperatures or prolonged exposure to cold air can cause synthetic leather to freeze, crack, and harden. Moreover, if some furniture is placed in a humid room, it can easily lead to damage of the surface film, thus shortening its lifespan.
