Here is a vintage 1960s rubber seat cushion for the iconic Giancarlo Vegni armchair made in Italy. It measures 19-1/4” wide, 17-5/8” deep, and about 2-1/2” thick. The front screwholes are 16-7/8” apart; the rear ones 7-3/16.  Great condition with no rips, holes, or stains, just some little lumps. Winner pays calculated shipping. Thanks for looking!
