Leather Steel Lounge chair 1950s?

Hi all

I bought this Chair around two years ago in Islington/London the couple didn't have any history about the chair said they had got it about 10 years before at a antique auction in the area. they seem to think around 1950s and had some pillows made because it had lost shape.

There are no markings on the chair but seems to be very well made. Anyway I really like the design and I'm just curious to find out some information about it. any help or information would be much appreciated.
