HEY-SIGN, based near Düsseldorf, combines sustainability, eco-friendliness and high-class design using natural wool felt. The material has many outstanding quality features, the fibres are durable, stain resistant and help to absorb sound. This is why HEY-SIGN designs not only feature in private homes, but do exceptionally well in office spaces. Smartphones and tablets have changed working environments, allowing flexible assignments of office desks. But they have also made it necessary to create spaces where people can retreat and relax. In recent years, HEY-SIGN has put a greater focus on customised elements for the business world, especially because the sound-absorbing quality of felt makes it so well suited for this environment.
