This is a first for us, a version of the famous Loop chair that we did not know before. We know a version with armrests and leather cushions for the seat and back of the chair, made for indoor use. On these two chairs, the very neatly constructed metal frame that makes up the base and armrests could be a special order. The chairs date from the early 70's with a very nice natural patina. One of the two pieces has a small gap on the back of the seat which does not pose any concern for the solidity of the piece. Sold as a pair, we do not separate the set.
