Ragnar Helsén designed the ‘Armchair 3543’ during the late 1960s for Swedish retailer Svenskt Tenn. Wing chairs were a popular style during that era, and have endured thanks to their quality and comfort. This vintage find rests on a wooden frame of straight, square legs, and has been freshly reupholstered using Clarence House’s sumptuous Liardi in Crostini, with a seat cushion in Sahara by Zak + Fox.
