The design of the armrest changes completely the perception of the product by enhancing one or more aspects of it by emphasizing like in the Wave version its welcoming and open effect. The armrest Wave is characterized by a movement which outlines an open curve for an immediately refined and unexpected result. The Davis system features a wide modularity with central, terminal, corner, chaise longue, dormeuse elements in addition to asymmetrical ones, which allows the development of linear or articulated compositions, without forgetting the important family of accessories which completes the offer with precious textures and materials. In addition to the armrest, with the Davis system it is possible to choose between five different types of feet and three different seat cushion comforts, to meet different aesthetic and usage requirements, more or less soft, more or less formal. The Davis sofa features a “patent pending” back cushion with integrated raised movement, which in the raised version increases the seating space and provides greater comfort.
