It's probably not Danish. I don't know if American furniture manufacturers used Danish rubber webbing--I don't recall seeing it on any American chairs but that doesn't mean a whole lot. Yugoslavia produced Danish style lounge chairs like this and the ones I've seen in person were of a light wood that had a tinted lacquer finish to make them look like walnut, which is what i think you have with this one. Yugoslavian-made chairs are usually incised "Made in Yugoslavia" on the inside of one of the seat, and often the mark is very faint. Check with a very bright light shown at different angles.
