As a reinterpretation of the multifunctional shell chair, HAL comprises a versatile seating family with a clean contemporary look. The shape of the seat shell provides great freedom of movement in a variety of sitting positions – even sideways or astride the chair.

The 15 different chair bases can be combined with a seat shell in polypropylene (HAL), in plywood (HAL Ply) or with a lightly padded shell covered in leather (HAL Leather). In the versions with a polypropylene shell and powder-coated base, HAL is also suitable for use in outdoor settings. As additional options, a fabric seat cover in various colours is available for all versions of HAL, and models with a plastic seat shell can be outfitted with a fixed seat cushion.
