Despite its mundane name the DS 1025 from De Sede is a beautiful sofa set that looks "like terraced hills" and comes in elements. Two elements will give you enough 1025 to create a two-seat configuration or "a pyramid or a small range of upholstered hillocks." The pyramid looks striking if not particularly useful to me. The hillocks are sort of half and half. Somewhat useful, but only somewhat striking. More elements give you more configuration options, etc.
