Manufactory for wooden fitness equipment & interior
Heimholz by Siehr is a manufactory based in Hückeswagen (North Rhine-Westphalia) that develops and manufactures fitness equipment and lifestyle furniture made of wood. The portfolio includes wall bars (MURUM®, ANNA®, HOLZMAX®, UNCLE X®, FILIBA®), fitness and weight benches, incline boards and gym cubes, wooden dumbbells and weight plates, a wooden water rowing machine, climbing and play equipment for children, as well as tables, cabinets and seating furniture. Certified woods such as oak, birch and walnut from Germany, Austria and Switzerland are processed; surfaces are treated with pollutant-free oils. The over 3,000 m² manufactory combines a traditional joinery workshop with two CNC machining centers, including the Holz-Her 7507 Push implemented in 2026. Handcraft characterizes production: every wooden component is sanded by hand, upholstery elements are individually upholstered, and every unit undergoes a quality inspection before shipping. In addition to private and B2B customers, Heimholz supplies physiotherapy and occupational therapy practices, hotels, boutique studios, clubs, daycare centers, as well as interior outfitters and architectural firms in almost all of Europe, Asia, the Middle East, the USA and Australia.
