"The Fishline Chair is an exploration into ways of finishing wooden surfaces that go beyond the usual applications," say the designers.
The transparent thread was first dyed in different shades then meticulously wound round every surface of the seats, legs and backrests to create "a new luster and fine unevenness".
The project will be on show at Interieur 2012 in Kortrijk, Belgium, from 20 to 28 October.
If you like these, Nendo aren't the first to cover furniture in threads: Tokyo designer Keisuke Fujiwara decorated bentwood chairs by German furniture brand Thonet in twelve kilometres of coloured yarn back in 2010 and Dominic Wilcox spent 75 hours wrapping multi-coloured cotton thread around five walking sticks in 2009.
