Special features of the Pi A.1 chair are the quality and processing of the used material: a deformable veneer that is flexed three-dimensionally in the production process lends the chair its lightweight appeal and reliable rigidity. The design provides effective protection against back strain and supports a healthy sitting posture. Chair legs and seat are connected by a seamless metal frame. This combination of materials contributes to the stability of the construction and defines its appealing and self-reliant appearance.
