Wilhelm Renz was a German furniture manufacturer, known for producing high-quality, functional Mid-Century Modern pieces, especially innovative metamorphic tables that transformed for space-saving use, featuring rich veneers, wood grains, and classic designs often attributed to designers like Walter Wirz and Rex Raab. The company started in 1882, but Wilhelm Renz took over and branded it around 1902, building a reputation for premium German craftsmanship in the mid 20th Century.
