Help Identifying a Danish Modern Chair  

Hi eveyone,
I have a set of 4 danish modern chairs that I am having difficulty identifying. They appear to be two-tone in colour, (possibly rosewood and teak) with orange (polyester?) upholstry on the seat. They are marked with "MADE IN DENMARK" on the underside of the seat which appears to be stamped.

I borrowed this photo from an online source, but they are exactly like my chairs (there was no information on the online source, unfortunately)

Any help would be appreciated. Thanks!
