Eero Aarnio bubble chair produced by Adelta. designed in 1968 in Finland, the acrylic bubble chair. what a leap in time, they heated up the acrylic en blowed it up. the conversational techniek was never seen in the furniture branch. the leather seat is still original, there some slight seeing of using. see close up picture. there is a label stamp unfortunately i polished out the text. so the sticker is still there.
