ID Danish lounge chair  

Hello,
Can anyone identify this lounge chair? I have not been able to find it on the web or in any of my books on Danish furniture. (I assume it's Danish, but of course I could be wrong.) It belongs to friends who told me they purchased it new from Design Research in Cambridge, Mass. in the 1950s or early 1960s.
Thanks for your help.
(P.S. I hope I uploaded the photo correctly. I'm a long-time lurker on this site with only a few previous posts, and it's my first time uploading here--or using Flickr, for that matter.)
