Hopmi chair Gerrit Rietveld HM Mertens


Hopmi chair with tip-up-seat by Gerrit Rietveld

In 1932 Gerrit Rietveld designed two different chairs for Hopmi, one of which had a tip-up-seat for theater/cinema Vreeburg in Utrecht, above which he lived for many years. HM Mertens saw this chair, adapted it and used it the same year in the Remonstrantse church he was working on. (architect J. Roodenburgh) These were produced by UMS which later became Pastoe. He replaced the seat and back with his own and added the armrests.

The frame by Gerrit Rietveld is designed for easy assembly and disassembly with the chromed Torpedo nut/bolts patented by Hopmi, who usually made gas-pipes and bicycles but wanted to expand into furniture. The chromed Torpedo nut/bolt has a double thread to connect two steel tubes without welding.
