Found it ! It's called the "Poang" armchair, fabric cushioning, laminated birch, and is at present in UK priced at £55 sterling - incredible value. (Online and in store).
Oh, if you don't mind falling asleep in it - there's a rocking version !
There'squite a few versions of it - upholstery being the difference - from leather/faux leather to a kind of poly stuff which I suppose is for the patio !
