Her comes some better pictures of the aubergine PANTONOVA CHAISE LONGUE from the early 70:ies..
The fabric is MIRALASTIC wich was first intended for norweigian ski socks but was then re-discovered by the Mira-X coordinator and used for a lot of Panton furnitures.
This elastic fabric was perfect for refurnishing furniture so almost all of Verners furniture producers used this fabric from 1969-1985.
