3D model of POLIFORM SYDNEY SOFA | DESIGNER: JEAN-MARIE MASSAUD | A contamination of styles, a mix of trends, perfect symmetry between oblique and orthogonal lines, sharp and rounded corners: Sydney’s design transforms a series of geometric volumes into a soft monocoque sofa. Sydney is distinguished by its slender feet and the L-shaped elements that make up the seat, which can be completed with freely arranged cushions of different sizes.
