Introduced in 2001, the Groundpiece sofa, crafted by Antonio Citterio for Flexform, has achieved best-seller status over the past 25 years. Although it was initially criticized for being 'too simple' and lacking a clear identity, its popularity surged. Drawing inspiration from the minimalist works of Donald Judd, the sofa features a low, deep seat adorned with ample cushions made from goose down or Dacron. Its natural fiber palette, including linen, cotton, and cashmere, encourages a laid-back seating experience. Flexform has engaged photographers such as Gabriele Basilico to offer new interpretations of the collection, enhancing its cultural significance. With its modular design and multifunctional aspects, it seamlessly integrates into diverse interiors while showcasing Flexform's hallmark elegance and clean lines.
