Description
A rare and highly desirable set of six original ‘Flex’ dining chairs designed by Gert de Lange for Thonet in 1969.
An icon of late Modernist European design, the Flex chair was awarded the prestigious Gute Form Prize in 1969, recognising its innovative design, functionality, and aesthetic excellence. Combining sculptural simplicity with exceptional comfort, the chair perfectly embodies the progressive design language of the era.
This sought-after set comprises six chairs with solid beechwood frames, upholstered in an attractive and characterful combination of original fabric coverings: four chairs in orange striped fabric and two chairs in plain orange fabric. The warm tones complement the elegant timber frames beautifully, creating a striking yet versatile visual presence.
The flowing lines, lightweight appearance, and ergonomic design belie their robust construction, making them equally suitable for dining, conference, hospitality, or residential settings. The chairs retain their manufacturer’s marks and present exceptionally well, displaying a gentle patina acquired through decades of careful use.
Comfortable, practical, and visually distinctive, they represent an excellent example of award-winning European furniture design from one of the twentieth century’s most respected manufacturers.
An increasingly collectable and sophisticated set that would complement both contemporary and vintage interiors.
