It's a rather battered bentwood 3 seater with green slightly embossed cushions.
For many years while I grew up, a bentwood 3 seater sat in our sitting room. A few years before she moved, my Mum had the whole set reupholstered in that same green, slightly embossed looking fabric. When she moved, she didn't have space for the 3-seater, so sold it.
I'm convinced it's the same sofa! Those sofas were never common, and the green fabric was not the original. I'm convinced our family sofa has a new career on telly!
