Sinus is a modern classic from 1976 which was already ahead of its time when it was first launched. With swinging spring steel rockers, the form of which gave it name, and an upholstery as unusual as it is comfortable. The round upholstery elements of the seat and back are maintained by leather belts. To celebrate the company’s 50th jubilee in 2004 it made a return to our collection to stand for the timeless and innovative design of COR.
