My first thought was that the chairs were Swedish ( 2nd was British) A quick image search produced one hit for the exact same chairs.
Nils Jonsson for Troeds ;70's era.
However, the seller has not shown any images of marks/labels. So take this attribution with a pinch of salt.I couldn't find any other pics of the chairs on the net.
The seller is located in the UK , so they could possibly be British.
Image of set that I found.
