Twelve bases, one shell: how Kriteria adapts to a whole floor
Large projects rarely need one chair; they need one chair that behaves differently in nine rooms. Kriteria answers with the base list: black, white or grey nylon, steel with a polypropylene cap, polished aluminium, painted aluminium in black or white, versions with chromed column and castors, and two four-star bases with glides for seats that stay put — which the manufacturer explicitly excludes on tilting versions.
Above the base nothing changes: curved beech shells in non-deforming polyurethane, upholstered arms integrated into the seat, three backrests and sixteen covering collections. The declared standard is EN 1335 type C, tested to the edition in force at the time of testing.
La Mercanti supplies Kriteria to Indian projects: give us the room list and each configuration returns confirmed in writing by the factory.
