The Groundpiece sofa is a modular seating system designed by Antonio Citterio for Italian maker Flexform that emphasises relaxed, low-slung proportions and adaptable configuration options. First introduced in 2001, the sofa’s structure combines a metal frame with foam-padded elements and removable fabric or leather covers, supporting large cushions filled with goose down or polyurethane and Dacron. The system accommodates linear, corner and sectional layouts, with integrated shelf or console elements that can replace traditional armrests or provide flat surfaces for accessories.
The seating’s deep, informal profile is paired with cushions of varied sizes, allowing users to adjust comfort and spatial arrangement. Optional armrest units can be wrapped in cowhide or suede and incorporate hidden storage or flat tops that function like side surfaces.
