Creative people require creative solutions. This is a simple way of summing up the 4+ challenge. When four designers—Angelika Mosig, Andreas Notter, Jan Papenhagen, and Wolfgang Ott—collaborated with design director Roland Zünd (hence 4+), they were looking to find common ground and develop a family of chairs that met the very highest expectations and speaks for itself, its creators and to design specifiers. Conference and lounge chairs require different pitches and seat heights, so were conceived together, while contrasting fabric options were deliberately developed to allow specifiers to customize their solution. And together is how 4+ designers produced 4+ seating.
