Wooden Lounge or Armchair  

Hello!

I would be so grateful for some help identifying this lounge chair which was my great uncles. 

I’ve done a Google Image search and can’t find anything exact for it. 

There are some details that are similar to Walter Knoll/Antimott Cherry armchair from 50s. eg the seat ‘tray’ (with underhang slant). 

The back is not wooden spindles though, it has tension springs for seat and back. The back has a hanging fabric panel to cover the springs. Tension springs have cloth sleeves on them. 

I have no idea if the cushions are original! 

The arm has a distinctive shape from above. 

Looking forward to finding out if anyone has any ideas!
