On the eve of the Milan Furniture Fair, Ronan and Erwan Bouroullec have released a short film featuring their latest collection for Swiss furniture maker Vitra – two chairs and two tables called Belleville, or 'beautiful town'. Belleville is a new range by French designers Ronan and Erwan Bouroullec that can live both indoors and out, is light and easy to "grab and stack". It includes two tables, one round and one rectangular with black powder-coated cast aluminium legs, and tops finished in laminate, wood or stone. With two matching chairs made of black polyamide plastic frames supporting seamless, sculptural shells in polypropylene, ultra-thin plywood or upholstery. The collection itself draws from the same school of thought as the robust, industrial, no-nonsense honest designs of Jean Prouvé's Standard chair and  Cite collections, also produced by Vitra.

According to the designers, the technology Vitra uses to manufacture the single-piece frame involves an automated injection-moulding process with gas to quickly place pressure on the molten material and form it into shape.

"Production is about 3-4 minutes only, and then everything is finished. The 'one line' frame structure links the feet to the shells and continues into the armrests and into the backrest. Like a typographer does with the design of a letter, step-by-step we valued the proportions of this line in order to make it well balanced, but also to answer the demands of the production technology."
