The Modus chair was first created in 1972 by Tecno’s own Design Centre, in order to provide the Graphis office system with a chair with multiple functions. 

The aim of the Modus project was to obtain not only the creation of one chair, but a whole series of chairs, created by the intelligent combination of various components to form different solutions for different types of environment.

The basic element of these multiple solutions is a polished polyamide (nylon) body in black and white. There are two basic variants: Modus stackable chairs that can be attached to an individual trestle base in polished, die-cast aluminium, and optionally equipped with padded upholstery and armrests; and Modus swivel chairs on a 5-spoke base in polished die-cast aluminium and optionally equipped with padded upholstery, armrests, height adjustment, on feet or castors.
