Calla is an armchair in polyurethane foam covered with leather. The project comes from the desire to find a new chair that exalt, increase and underline the potential, the visual and tactile sensations of a material such as leather. This is an important feature of the goods by Martini's, which is a synonymous of elegance and value. The projectual idea belongs to the natural world, exactly from the elegant, refined and enveloping forms of the Calla.
