The original is near-impossible to find and to be honest, the reissue of the Eero Aarnio Cognac XO armchair isn't much easier to source either.
It's not actually a straight reissue of the 1966 Cognac V.S.O.P. chair (hence the slight name change), this version is bigger and 'more ergonomic', but still hads that distinctive fibreglass frame and some upholstery in a Tonus fabric in your choice of colour.
Of course it isn't cheap, with prices around the £4,000 mark, but there's no denying it's a head turner.
