Vintage low easy chair, age and origin unknown, estimated 1970s. This lounge chair has a frame made from tubular steel and a thick leather patchwork seat. The steel frame is in very good condition with only the slightest signs of corrosion. The leather seat has been cleaned and conditioned, and is in a good condition. There are some marks and colour differences from years of use, resulting in a nice patina. On the arm rests some of the leather has become a little rough, there are no tears and after good conditioning it is now supple again.
