In 2005, Christian and Michael Sieger launched the premium brand SIEGER, which aimed to enrich people’s daily lives with intelligent, aesthetically pleasing products and to fulfil the demands of the modern hospitality sector. For over 15 years, the brand has worked with the German Porzellanmanufaktur FÜRSTENBERG to create handmade porcelain collections. Bestsellers like the Sip of Gold champagne tumblers and MY CHINA! dinner service can now be found in countless apartments, five-star hotels, restaurants and luxury yachts. Behind the SIEGER brand is the agency sieger design, which has been coming up with iconic tableware designs since the early 1990s. The brothers’ creative work includes developing the Ritzenhoff brand and the TRIC range, one of Germany’s best-selling porcelain collections, for Arzberg.
