Wooden frame with elastic straps, with pad in expanded polyurethane in different densities upholstered in fibre coupled with fine velveteen. Base in solid beech-wood painted black, with anti-slip ferrules Seat cushions in feather with insert in expanded polyurethane with differentiated densities upholstered in cotton or cotton matelassé. Backrest feather cushions upholstered in cotton. Lumbar-support rolls in expanded polyurethane upholstered in heavy cotton. Elements upholstered in completely removable fabric or in leather with cushions having removable covers and structure with non-removable covers. Plaza is an urban arena turned domestic. The wooden structure of this sofa defines its space and the cushions play the role of casual by passers interacting in a square. This project is all about creating a gregarious space within a private dimension, one that varies to meet different needs. So, all the seats and backrests consist of cushions that vary in dimension, quantity, position, fabric etc…. all in a state of flux, just like our lives.
