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.

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.
