AC4

When designing the AC 4, the aim was to subtly integrate the functions required to provide the best level of comfort. Prior to this, office chairs were either designed for aesthetics or function. The AC 4, by contrast, integrates its ergonomic properties in such a subtle way that the constructional tricks are hidden away. The AC 4 creates a balance between advanced ergonomic functionality and subtle design. The innovative technology is neither showy nor hidden under foam padding. This makes

When designing the AC 4, the aim was to subtly integrate the functions required to provide the best level of comfort. Prior to this, office chairs were either designed for aesthetics or function. The AC 4, by contrast, integrates its ergonomic properties in such a subtle way that the constructional tricks are hidden away. The AC 4 creates a balance between advanced ergonomic functionality and subtle design. The innovative technology is neither showy nor hidden under foam padding. This makes the AC 4 an iconic object with an aura of elegance and uncompromising functionality. Automatic weight adjustment - The synchronous mechanism with large opening angle and automatic weight adjustment of the backrest resistance, ensure that the user’s weight is supported in every sitting position. Armrests - The multifunctional 3D armrests can be rotated by 360 degrees, which is very useful with e.g. table-oriented work. The aluminium ring armrests are an elegant variation for conference seating, especially when leather-upholstered. Ecology - 51% of the materials used to produce the AC 4 are recycled and 94% of all materials are recyclable.
