The 680 Class sofa is available in two variants: high-back two-seat sofa and low-back tree-seat sofa. It can be matched with an ottoman and various models of matching armchairs and small armchairs. The most interesting feature of the 680 Class sofa is the possibility to customize interior spaces by combining the sofa with ottomans, matching armchairs and small armchairs, playing freely with space, colours and cover materials.
