About Detterbeck – Die Manufaktur
Detterbeck – Die Manufaktur is a sole proprietorship based in Watzling near Dorfen (district of Erding, Bavaria), specialising in the traditional manufacture of spring cores for the classic car sector. For over 20 years, the company has produced spring cores for vehicle seats with hand-crafted precision using conventional techniques – both as series solutions and as individual one-offs and custom-made pieces for restoration projects. In addition to spring cores, seat covers are made to historical models, and for selected models seat cushions made of rubberised coir fibres are produced in line with the construction methods of the period. The product range is complemented by seat accessories and consumables such as wool felt/upholstery wadding (750 g/m²), jute burlap (365 g/m²), spray adhesive and upholstery clips including an upholstery clip pliers. The claim is faithfulness to the original and genuine craftsmanship instead of industrial mass production.
