This bent plywood chair resting on structural elements made from solid beech wood was designed by Marian Sigmund, one of the key artists affiliated with the "Ład" Artists’ Cooperative. At the turn of the fifties and sixties, the designer collaborated with the Bentwood Furniture Factory in Jasienica. His A587 chair was intended for export to Great Britain as a school seat. Skilful use of decorative values of bentwood structure, both from plywood and solid beech wood, as well as the contrast between natural and black-dyed wood makes the chair stand out by its style and beauty. The Bentwood Furniture Factory in Jasienica, where bentwood furniture has been manufactured since 1880 (since 1923 sold under the Thonet-Mundus brand), is now part of the Paged Group. The factory in Jasienica has prepared a new, modernized version of the Sigmund chair.
