Designing interactions, trajectories to take over the space available. Bikini is a landscape which is a child of its times and the society it represents. Whether used in waiting areas or homes, the seating system is absolutely flexible because there is no need for the layout of the space and the arrangement of the seating components to correspond. The components are varied in both look and function so that, unusually, they can be used in any setting. Stools, tables, coat racks, containers, shelves, screens, work surfaces, seats: every element combines to create interaction and communication. A mix of functions and meanings means that the idea of sofa as the piece of furniture used to watch TV or as simple resting place is revolutionized, turning it into it the very (open) heart of interaction.
