Modular and multi-functional seating is well represented at IMM. Clockwise from above left; e15 has Kashan by Philipp Mainzer, a freestanding sofa with modular elements, Ligne Roset has Pas Si Classique by Pascal Mourgue, a flexible low sofa that can be "docked" with a low table, Cassina is showing its new Mex line designed by Piero Lissoni with a circumferential frame that doubles as shelving and Haberkorn's Pure wood bench by Bernd Haberkorn with integrated LEDs.
