Brutalist oak low chair or children's chair, Dutch 1970s

Wonderfull small brutalist side chair in blond oak, dutch 1960s-1970s. This chair came to us as a possible children's chair but we have also heard it could very well have been a low workers chair ( the wideness of the seat and the "carved" seat would imply this ). There is a thin split near the backrest on the seat but this does not effect its look or feel in any way.
