Winny Quattro is a bed sofa designed in 1999 by Guido Rosati for Flexform. The sofa is made of a sturdy metal frame and wooden ribs padded with polyurethane foam. The cushions are softly stuffed with down for high comfort. The cushion is available in a choice of fabrics and colors, with the fabric version being removable. Winny comes with a patented pull-out mechanism which quickly transforms the sofa into a spacious bed, suitable for any living room, guest room, or smaller space.
