Product description
*** UPDATE 02.10.2026***: The sofa has since been completely and thoroughly cleaned. The current photos show the condition after cleaning.
The cream white / off white cover has been completely cleaned and is in a very well-maintained condition. Only two minimal residual marks, each approx. 1 cm in size and almost completely washed out, are present upon closer inspection. Slight color differences on edges or hidden areas are due to age.
For a model designed in 1976, the condition is at least very good.
