An Italian Seating Maker From Codognè
Diemme Office is the trading name of DIEMME S.r.l., based at Via Del Lavoro 25 in Codognè (TV), in the Treviso province of northern Italy, and reachable by phone on +39 0438 778211 or by email at dm@diemmeoffice.com. The company describes itself as a maker of "Sedute per ufficio e contract", seating for offices and contract interiors, and its homepage headline widens that to chairs for the office, the home and contract work, including smart working. The site is written in Italian with language switches for English, French and German.
Where it sells takes some reading between the lines, and the site does not spell it out. There are no prices and no shopping cart on the homepage or the About page. Instead the navigation leads to a product finder ("Trova il prodotto ideale"), a showroom page, a trade fair calendar ("fiere"), downloads, a pCon.planner link for specifiers, and a contact page, with a Login for registered users. That structure points to a business that sells through projects and trade partners rather than direct online orders. The site does not publish which countries it delivers to or a list of dealers, so a buyer outside Italy will need to contact the company to find a local partner. The footer links to a "Condizioni di vendita e Garanzia" page (terms of sale and warranty), which is where the commercial terms are published.
Where Diemme Chairs Have Gone
The About page carries a long project map titled "dove abbiamo già lavorato" (where we have already worked), and it is the clearest evidence of Diemme's reach. Italy and Spain dominate, with many entries in Valencia alone: Óptica Millennium, Faurecia Interior Systems, Coworking Parc Central, Loewe, Peugeot, Hotel Don Carlos RH, and the ANPE Sindicato independiente. The Netherlands appears often too, with Van Dijk Groep in Gemert, Kuijpers, Quintes, IVS in Veghel, Holland Immo Group in Eindhoven and Feyenoord Rotterdam.
The list also runs well past Europe. It includes the Hotel Pullman in Santiago de Chile, Design Group Latinamerica offices in Maracaibo and Caracas, a Ministry of Culture office and a separate project in Riyadh in Saudi Arabia, Media Vest in Dubai, Bright Commodities in Mumbai and RD Engineering in Kanjurmarg in India, TLS Contact in Agadir, and a Grand Salle in Tunis. Closer to home there are projects at Paris Orly international airport, the Ospedale San Matteo hospital in Pavia, a university in Munich, the British-Georgian Academy in Tbilisi, a co-working space in Ukraine, the Radisson Blu Hotel in Brussels, the RSM Tax & Accounting office in Luxembourg, Resalta Offices in Ljubljana and the Snappi Workplace Hub in Athens. The newest entry is the ATI Project Headquarters in Pisa, dated 2025, where the homepage says Diemme supplied the seating for the top seven floors of the North Tower.
Diemme has a base in Chile as well: the homepage announces the Spazio Diemme in Santiago de Chile, described as a new meeting point dedicated to Italian design, consultancy and the development of new projects. The events panel lists an upcoming appearance at Design Nation in Kortrijk, Belgium.
The Range
The product menu splits into six groups: operative (task and operator chairs), direzionali (executive chairs, the part of the range that matters for this category), sedie (side and visitor chairs), sgabelli (stools), poltrone e divani (armchairs and sofas), and complementi (accessories and complementary furniture). A separate collections menu organizes the range by setting instead, under office space, community and lounge area. There is also a rivestimenti section for upholstery and covering materials.
The homepage describes the chairs, armchairs and sofas as having a sober design that is never the result of simplification but of a subtle search for balance, and it frames quality as a selection of eco-sustainable materials, careful and distinctive craft work, attention to detail and daily research into new technology. The line "[ furniture to connect people ]" heads a short statement about designing workplaces where people feel as comfortable and free as at home.
The site's featured story is the ARPEGGIO seating system, designed by PRINCIPIOATTIVO Architecture Group for Diemme, which the homepage says won the Gold Award in the Product Design category of the IIDA Italy International Design Award 2025. The homepage also runs editorial pieces on flexible co-working spaces, learning environments and the contemporary office, which show where the company sees its chairs being used.
How the Company Started
The About page, titled "Lavoriamo dove siamo nati" (we work where we were born), tells the story in the founders' own voice. The two founders met in 1985 while working in the upholstered furniture sector ("il settore dell'imbottito") for two different companies, later became colleagues, and in 1995, on a cold winter day, decided to join forces and start Diemme. The company first worked as a subcontractor for other firms, but the founders say their aim was always a coherent system of seating of their own. After designing and building their first office chair, the first catalog followed, and then the first trade fair.
The page says Diemme came through the years of economic crisis by choosing to work with architects and designers and by adding sofas and small armchairs to the office chairs it already made. It credits its local partners and the area it still operates in for giving it the courage to open up to new markets. The founders describe the business as a project in continuous evolution rather than a finished one, and after more than twenty years they say they feel at home. A downloadable company profile is linked from the same page.
Sustainability and Certifications
The homepage lists the goals Diemme says it set from the start: attention to ergonomics, chemically safe materials, reducing waste, using recyclable materials, clean and renewable energy, and less plastic packaging. The navigation has separate entries for comfort e sostenibilità (comfort and sustainability), certificazioni (certifications) and conformità di prodotto (product compliance), plus a Politica Qualità (quality policy) link in the footer. The homepage and About page do not name individual certifications, test standards or weight ratings for specific chairs, and they do not publish adjustment ranges for the executive models.
Who It Suits
Diemme suits architects, interior designers and companies furnishing a whole office, hotel or public building who want Italian-made executive and meeting seating and are happy to work through a project conversation rather than a checkout. The project map shows the company has delivered into offices, hotels, a hospital, an airport, universities, libraries and private homes across a wide spread of countries. It is less suited to an individual who wants to compare prices and order one executive chair online, because the site shows no prices and routes buyers through its showroom, fairs and contact page. Anyone outside Italy should ask the company directly who handles sales and delivery in their country, since the site does not publish that.
