Rare tubular chair named hopmi designed by hermann friedrich mertens (1885-1960) for ums pastoe in collaboration with hopmi in 1932. Hopmi stands for hollandsche patent metaal industrie. From 1932 to 1934, hopmi worked with ums pastoe on the production of a series of tubular furniture, characterised by the special torpedo nuts.
