with the DS-142 model, you bring a piece of top-class Swiss engineering from de Sede into your home. This piece of furniture defies conventional categories: it's an armchair, a chaise longue, and a compact sofa all in one – a true chameleon. The high-quality leather upholstery is a brilliant white, perfectly complementing the futuristic, organic design. The absolute highlight is the eponymous "Wing" function: the backrest and armrests aren't fixed but can be adjusted independently. In the image, the side wings are folded down, creating an open, wide reclining surface. However, they can be ratcheted upwards in stages to form a comfortable hollow for sitting or leaning back. This complex mechanism is supported by a delicate, chrome-plated steel frame that appears both technical and light. The visible decorative stitching on the wings testifies to the craftsmanship of the manufacturer. Additional loose cushions provide personalized comfort for the back. In the image, the side wings are folded down, creating an open, wide reclining surface. Light wear consistent with age and use.
