Rare Pair of Folding Scissor Easy Chairs 1960s

Fantastic pair of folding scissor easy chairs from the 1960s.
Unfortunately I don't know the designer, nor the manufacturer. Most likely they come from the Netherlands.
Very good looking chairs with simple and straight lines. Easy to store as they are foldable and comfortable as well.
They are made of solid pine wood.
The chairs are in good condition, some normal traces of use.
