Rietveld Originals was established by Gerrit Rietveld’s grandson Egbert Rietveld, aiming to bring his grandfather’s furniture designs to the public’s attention. The collection includes all Gerrit Rietveld’s furniture designs currently in production. It consists of furniture produced by Rietveld Originals as the official licensee of the Copyright Foundation Dr G. Th. Rietveld plus the designs published by Cassina, Gispen and Tecta.

The Gelderland collection offers an impressive sample of Dutch design history. From the first piece of furniture in 1936 onwards, it has all been about timeless, comfortable, sustainable and reliable design lasting for generations. By attracting leading designers such as Ib Kofod Larssen and Rob Parry in the 1950s, the foundations were laid for the present Gelderland principles. In 1969, Jan des Bouvrie made his debut as a furniture designer with his 430 Cube sofa. Many designers followed, including Henk Vos and his sons Bart and Roderick, Stefan Scholten & Carole Baijings, Remy Meijers, Lex Pot and Studio Truly Truly.


Atelier Artiforte was founded in 1930 in Rotterdam. Henk Fillekes was the driving force behind the innovative designs that made the company famous in the 1950s and 1960s. Besides Fillekes’ work, the collection contains designs by architects Kho Liang Ie and his teacher Johan Niegeman. RSGA Design has acquired the rights to the lighting of Atelier Artiforte. This adds a new chapter to the history of this unique collection of timeless and unaffected lighting with Dutch design tradition. In addition to classics by Fillekes, Niegeman, Kho Liang Ie and Aldo van den Nieuwelaar, Atelier Artiforte will be introducing new work by today’s best lighting designers such as David Derksen, Rick Tegelaar and Rachel Griffin.
