This year is the bean bags' 40th birthday.
Known in Italian as 'il Sacco' it was designed by Piero Gatti,Cesare Paolini and Franco Teodoro in 1968 and produced by Zanotta.
Besides inhabiting many homes it went on to become a cult object of informal design making it into MOMA's hall of fame in 1972. Since then il Sacco - in its many variations has gone on display in 26 of the worlds' important desgin museums.
Definitely a case of 'been there & done that'.
