Sofacinne is a modular seating system designed to facilitate dynamic spatial configurations and personalized user experiences. It comprises discrete, elongated cushion modules, strategically layered to form a cohesive, yet adaptable, seating topography. The modules are constructed with an oversized plain weave textile, providing a tactile and visually engaging surface that references traditional weaving techniques. The design incorporates a mechanism for selective vertical displacement of individual cushion modules. This manipulation generates variable spatial volumes and seating arrangements, affording users the ability to customize their environment. The capacity to extract multiple modules simultaneously enables the creation of distinct spatial partitions, fostering both communal and private seating zones within the same unit. Sofacinne functions as an interactive furniture element, promoting a reciprocal relationship between user and object. Its modularity and adaptability encourage active engagement and exploration, empowering users to define their seating experience. This system transcends conventional seating solutions by integrating spatial dynamism and user agency, ultimately enhancing the occupant's interaction with the surrounding environment.
