Since 1990, Dedon has transformed outdoor living by inventing the first durable synthetic fibre for outdoor use: the original Dedon Fiber. Combining weather resistance, longevity, and timeless aesthetics, the company has set new standards for luxury in outdoor furniture. What began as a pioneering idea has evolved into a highly relevant global brand. Dedon combines industrial precision with traditional handcraft. From the development of its proprietary fibre in Germany to hand-weaving in its fully integrated manufacturing facilities in Cebu, Philippines, the brand maintains control across its entire value chain. Close collaboration with internationally renowned designers ensures that each collection strikes a balance between technical performance, timeless design, and long-term relevance. Today, Dedon is present in more than 80 countries and continues to set standards for sustainable luxury in outdoor living. Since joining Diethelm Keller Group in 2014, Dedon has strengthened its global presence while staying true to its vision of creating outdoor spaces that bring people, nature, and design together – sustainably.

Gloster has built a strong market position through its commitment to thoughtful design and carefully selected materials. The company’s roots reach back to West Africa in 1960, where a group of passionate entrepreneurs and furniture makers took the first steps on what would become a successful journey in furniture craftsmanship. In the 1980s, growing demand and reliable access to Gloster’s signature material – plantation-grown teak – had led to moving manufacturing to Indonesia. The Gloster factory has flourished there ever since and remains central to the brand today. Craftsmanship has always been at the heart of Gloster. Its furniture is not the result of anonymous mass production. Every rounded corner and every joint is shaped by hand. The quality of each piece reflects the experience, care, and skill of the people who make it. Today, the same passion and conviction that defined the brand from the outset continue to guide its work. Therefore, Gloster remains true to its identity as a furniture maker with a clear focus: designing and building exceptional outdoor furniture. Diethelm Keller has been involved with Gloster since its founding and acquired full ownership of the brand in 2011.

Sustainable ideas for enduring values – this philosophy has guided Garpa since its founding in 1979. Today, as in the past, the core of this long-established company is classic garden furniture made from FSC-certified teak wood. From the very beginning, Garpa has combined craftsmanship, material quality, and a deep respect for nature to create furniture designed to last. Over the years, Garpa has expanded beyond teak, working with materials such as stainless steel, alu minium or textiles, developing expertise in modern furniture design. As a result, each collection is designed holistically: every piece can stand con fidently on its own, while also inviting creative combinations of materials and styles. Garpa furniture is comfortable, functional, and aesthetically pleasing. A distinctive feature of the brand is its commitment to providing an exclusive service in German-speaking markets, characterised by personal advice, continuity, and long-term customer relationships. Garpa has been part of Diethelm Keller Group since 2014.
