Impossible to judge from the photos, but some features suggest a replica. At what price can you buy the set?
This informative thread from 2013 discusses MR chairs and the fact they were made by many companies, from licensed versions by Thonet, Stendig, and Knoll, to a multitude of "pirate" versions . I think the opinion of the poster Vamasucci makes a lot of sense - that when a model is produced by so many different makers, the quality of the materials and construction are more important than the name. Unless you have a set of original versions by Berliner/Bamberg Metallwerkstätten, which sell for $$$$.
