Wegner?  

These chairs certainly do have a Wegner feel to them. I do not recognize them as Wegner, but he did design a lot of chairs. If they were Wegner, they aren't Carl Hansen. It is very, very doubtful they would be Johannes Hansen. And I seriously doubt any this could be any of his pre Carl Hansen makers (Fritz Hansen, A. Mikael Laursen, and some others). They could only be later designs for PP Møbler, and they are not on PP's site.
And I do have one subjective reason to think they are probably not Wegner: the spindles are not inserted into holes in the seat, with the seat weaving going through slots in front of the spindles, as Wegner liked to do, but rather into a cross bar at the bottom of the seat back that seems to have been added to the design specifically to avoid the challenge of weaving around them.
Also, Wegner's later designs tended to have laminated back rests with contrasting wood patterns. In other words he moved away from the wishbone chair style bent wood backrest.

It is difficult to see the exact details for the table which i suspect was made by K P møbler. You should be able ti find a sticker on the underside along with a large paperlabel giving care instructions for the table.
The chairs are not wegner but a generic design from Haslev mæbelfabrik or could even be Kvist møbler.
Would require more detailed images to confirm that.
