Rare Hopmi Tubular Chair by Architect H.F. Mertens for UMS Pastoe, 1932


This rare tubular Hopmi chair is a design by architect H.F. Mertens for UMS (later Pastoe) and was presented in 1932 in their collection as an easy to transport and assemble chair The patented Hopmi fitting was a special tubular pipe with cut tread with a torpedo nut that connected the pieces of the chair together when you tighten it Hopmi was a company that produced gas pipe fittings and bicycle parts in Utrecht The idea and concept was its way ahead of its time and also due the economic crises it failed After the second world war companies like Pastoe and Ikea produced their furniture with the same concept for easy transportation and assembly Gerrit Rietveld also experimented with this type of connection in the 1930s and he made two known examples of his Hopmi chair with identical connection, one of which is in the Centraal Museum in Utrecht A museum collection worthy chair.
