Trio is an all-rounder contract chair! In fact: 1100 Trio is an all-embracing series, featuring a gently curved and pleasantly resilient plywood seat shell that can be mix and matched with five distinct steel frame variations: a four-legged frame, a sled base, a bar stool frame, a cantilever frame or a bench frame. Combined with a contemporary design language, these multifunctional variations are suited for a plethora of environments. This extensive product family by Robert de le Roi meets all the specific quality and safety standards for public areas, and therefore lives up to the high functional as well as aesthetic requirements laid down for much-frequented rooms. Trio is available with low-flammability surfaces, or with hygienically impervious fabrics from the kuschmed® Hygienic-Line. Through a wide spectrum of upholstery variations, fabrics and materials in combination with the distinct frames, the Trio variations prove to be extremely versatile and varied.
