UD, inspired by a red-wine glass, is a sofa chair with a capsule-like silhouette. Free of screws or redundant ornamentation, it is simple yet elegant. Its profile with smooth and rounded curves demonstrates pure elegance. The uncluttered seat and smooth back create a sleek silhouette and conveys a sense of relaxation. The wide base with the built-in gas spring creates a soft suspension. It can turn 360 degrees, giving the user a high degree of mobility and flexibility.
