It looks like the model is an F510, which dates from the late 1960s and has a wonderful space age look about it. According to the owner, the swivel chair is in ‘very nice condition for its age’ and has ‘the best swivel action of any chair I have ever sat in’.
As for condition, there are ‘some small marks and scuffs on the leather at the top’, but these are ‘easily removed/recoloured’. There are also a couple of ‘small chips’ in the base, and the leather seam could ‘use a couple of stitches at one end’. Overall, however, these are described as ‘very minor’.
In terms of the price, no bids and no reserve, with that opening price at £220.
