London-based design studio Fredrikson Stallard designed a sofa that looks like a rock as part of the studio’s ‘Momentum‘ collection. Made of polyurethane, glass fibre and polyester, the piece mixes elements of furniture and sculpture. It comes in two distinctive shapes and colors. The studio, which was founded by Patrik Fredrikson and Ian Stallard, specializes in design that is both experimental and avant-garde.
