A fabulous de sede full leather ds 600 "non stop" or snake shaped sofa. the ds 600 was designed in 1972 by ueli berger, eleonore peduzzi riva, heinz ulrich and klaus vogt for de sede switzerland. this stunning sofa consists of 16 full leather modular parts, color cream or ivory. the high quality leather is very soft and gives a great seating comfort. the sofa is in very good condition. the elements are connected with a plug-in hinge and a construction with a zipper. this is one of the most popular modernist sofas, modular seating systems. The non stop sofa is a versatile sofa which works well with any style of interior design, decor including italian modern, danish modern, mid century modern, contemporary, vintage, traditional and post modern to name a few. a must have for design aficionados and collectors alike. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
