Trio sofa by COR

Designer Franz Hero and Karl Odermatt. (team form ag)

Everything remains different.

Invariably variable

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.

NOTHING IS OBLIGATORY, EVERYTHING IS POSSIBLE:
TRIO CAN BE PUT TOGETHER JUST THE WAY THE OWNER LIKES IT.

Much about Trio has remained unchanged over all these decades — such as the high-quality materials, the intricate workmanship, the intelligent interior that houses a real slatted frame, and the clear edge with the distinctive double seam.

Other things can be changed time and again: like the combination of stool, backrest and corner rest to create all kinds of shapes, and the cover fabric. Here, Trio is sporting one of its nine exclusively woven birthday garments in a plush brass yellow.
