Trade terms for professionals and design studios
Most upholstered executive chairs are ordered with a single colour reference. Kriteria asks for two, and the manufacturer spells out why: the first code identifies seat and backrest, the second identifies the outer parts of the armchair. One surface is the one you touch for eight hours; the other is the one your visitor reads from the doorway. Kastel lets you decide them separately.
Underneath both runs the same construction: curved beech plywood shells padded in non-deforming polyurethane, upholstered arms born inside the seat, and a choice of three backrests — high with wings, high without, medium — the conference chair of the three. The declared standard is EN 1335 type C, tested to the edition in force at the time of testing.
La Mercanti ships Kriteria across the United Kingdom and beyond: name the two codes and the configuration returns confirmed in writing by the factory.
