A comfortable all-round chair for offices, commercial buildings and homes.
Design: Mathias Seiler
Biala’s wrap-around backrest provides a feeling of comfort and, with its light upholstery, is vaguely reminiscent of a club chair. As a range of chairs, Biala has been designed with numerous frame options, enabling it to be used in many different settings in the office or at home. The seat and backrest upholstery can be covered in one or two colours or even in different fabrics. In addition to the individual chair, Biala is also available as a two-seater. This comfortably seats two people in a small area, and can be combined with the individual chairs to create attractive groupings.

Wrap-around backrest

The backrest, which cocoons the seat, provides a feeling of comfort and enables lots of sitting positions. The seat is optionally also available rotatable.
