Thanks to the wide range of arrangement possibilities, SO-one perfectly adjusts to each user providing them with optimal working conditions. An aesthetically pleasing double-sided upholstered backrest, 2-D and 4-D adjustable armrests, a contoured backrest with visually attractive stitching, a free floating possibility and a backrest lock in 5 positions – these are the biggest advantages of the line.
SO-one is a model that allows for combining two different upholstery colours – the right colour arrangement makes the chair an element that highlights the character of the office. The horizontal stitching on the backrest is an additional visual advantage.
