Armin Wirth was not initially a furniture designer, but an engineer for scales. However, he then designed the nestable Aluflex chair for Rudolf Steiner - a good friend - in 1951. This chair surprises with its economical, horizontal stackability (nesting), its weight of only 3 kg, its robustness and the high level of seating comfort.The chairs are in very good condition. There are only inconspicuous, age-related scratches on the metal frame of the chairs.
