The 40/4 chair by David Rowland is considered one of the most important and innovative designs of the 20th century. Known for its outstanding stackability - up to 40 chairs can be stacked to a height of just 1.20 meters - the 40/4 combines excellent ergonomics, high seating comfort, versatility and timeless elegance. This design icon sets standards in terms of compactness, adaptability, durability and aesthetics. In 2000, the 40/4 was named one of the "Top 10 Commercial Interior Products of the last 50 years" by Contract Design Magazine and is still considered the gold standard among stackable chairs. The 40/4 chair is not only functional, but also extremely practical: two people can set up or stow away up to 500 chairs in just a few minutes. The chairs can be quickly linked together in rows and stacked on trolleys, allowing space-saving and flexible use in a wide variety of spaces - from large event halls to small meeting rooms. David Rowland developed the chair based on extensive ergonomic studies and his MOD (Maximum Order Dimensioning) system to create a shape that provides optimal comfort for most people - even when sitting for long periods of time. The minimalist and elegant design of the 40/4 blends harmoniously into a wide range of architectural environments - from historic buildings such as St. Paul's Cathedral in London to modern museums, offices, restaurants or private homes. The chair is available in a variety of materials, including plastic, metal, wood veneer or leather, making it perfectly adaptable to any setting. 40/4 is not only impressive for its shape, but also for its robustness and durability, making it ideal for intensive use in public and commercial environments. In collaboration with HOWE, the 40/4 family was expanded from 2004 and now includes not only the classic chair but also versions with a writing tablet, lounge chair, bar stool, outdoor chair, solid wood versions and swivel chairs - so that a uniform design can be implemented in all areas. The 40/4 chair by David Rowland is therefore a true design classic that combines functionality, comfort and aesthetics in a unique way.
