IKEA GAMLEBY extendable dining table for sale - in a very good condition, made out of wood. (This is not available on IKEA anymore!)
The sides are easy collapsable; see pictures for examples. When fully extended, it can sit up for 6-8 persons.
€100 for the table.
If you are interested in the chairs, I have three of the STEFAN chairs available and willing to let them go at €20 if you will take all three of them. Otherwise it will be €10 per chair.
Pick-up in Wageningen.
