Basel is a subtle and sophisticated woollen upholstery textile, designed by Herzog & de Meuron for the Grand Hall of the Elbphilharmonie Hamburg. Available in ten versions, it offers a wide variety of expressions, ranging from formal to informal, smooth to rough, and dark to light.

Basel comes in five different patterns, each of which is available in black or white. These are characterised by unique, fine structures created with simple bindings. The difference between them is the manner in which they are constructed. Consequently, whilst they all feature small, precise shapes, the size and form of the shapes for each pattern is different: some are little triangles, others small squares or ovals.

The patterns combine very well, and when used together, project a strong sense of tactility and complexity.
