Elegant and refined, the Istana sofa is a concentrate of emotions and well-being. Designed by a great master of design, it is a product characterized by its straight and curved lines, male and female: the lightness of the neoclassical line with a touch of 50s taste, gives it a contemporary classic style. For all the products that need CAL TB 117 certification but do not have it, it is possible to add an interliner between the padding and the coating to fulfill the requirement.
