Ooooh
Better jump on it!
That chair looks worn and lovely.

Similar, but no...
...the back is the wrong shape, there are buttons on the cushions and the legs are different to the Hans Olsen - or that Hans Olsen, at least.

I have a Hans Olsen chair at...
I have a Hans Olsen chair at home (for sale btw) with a high back and it almost is identical to this one. Seems on this picture that the armrests have a little curve over the long side while mine hasn't.
There are a few for sale on the radar as well.
The cushions are loose, so they could have been redone at some point.
My Hans Olsen chair isn't marked but some do have markings, when they are you should see a stamp or sticker on the bottom frame.

and:
the legs shouldn't be round but like a piece of wood which has round edges and the small side faces to the front (difficult to explain in English).
So not round but rectangular with round edges.
And the back should go straight, also on the sides.
