This is one of the most iconic chairs that is so easily recognised. It is known by so many names; the Vienna, "consumer chair", "coffee shop chair", "chair of chairs" or just plainly No. 14. From 1859 to 1930, up to 50 million of these chairs were reproduced. Last year, a new twist was added. They have decided to knot (that's what the K stands for) one of the legs. I think it would be fun to have a couple of pieces of the classic pieces and have one or two of the knotted pieces mixed among them. Then your guest might just discover the knot in their chair and have something to rave and rant about or feel special.
By the way, there is also a kid's version of the classic piece. Adorable.
