Tonus 4 is a colour update of Tonus, an elastic upholstery fabric by late textile artist Nina Koppel. Ideal for modern organic furniture and characterised by rare colour richness, it comes in a total of 47 hues, of which 19 are new.
The story behind Tonus starts at the end of the 1960s, when the furniture manufacturer Kevi A/S introduced the Jørgen
Rasmussen office chair. The chair was in a sculptural form, which made upholstering it complex and expensive. The search for a stretchable fabric began and this led to the development of Tonus.
Now recognised as a classic textile, Tonus brings colours to life in vibrant, precise fashion. Building on this characteristic, the intensity and brightness of all the colours have been increased.
The new earthy, golden tones in the palette are taken from Nina Koppel’s original colour archive. They show her brilliant sense of colour, which reflects that she mastered all facets of the colour design from the warm tones associated with spices and Oriental mysticism, to the cooler Nordic aquamarine colours.
