Trio

Maximum mobility was the credo of the Swiss designers Franz Hero and Karl Odermatt of team Form AG when they created the original model of the upholstered furniture Trio in 1973, whose laid-back, loungy landscapes were a stark counter-design to the hard armrests and rigid backs of their time. With just three simple elements — stool, backrest, corner backrest — Trio opened up an almost endless number of variation possibilities. The quick-change artist is still doing this today, 50 years later: invariably variable.
