Strong folding chair - graceful yet robust. Resilient in its construction and iconic in its design - a benchmark for many successors in this product category. What you might not expect: the design of the ACM is dated in the literature to the early years of the 20th century. Currently, it comes from the production of a Polish chair manufacturer whose origins also lie in these early years of chair production. In terms of both form and construction, this chair, made of plywood in the seat and back and with a bentwood frame as a strong design element, is an archetype that can hardly be improved upon.
