PIER LUIGI COLLI STOOL, 1950s

Ergonomic chair "Do More," manufactured by Tan Sad in England for Ahrend around 1920.

A special, rare, vintage ergonomic chair in its original condition. It was used by employees of the Opcina tramway in Opicina, making it not only an interesting industrial chair but also one with a fascinating history and story. Ahrend introduced itself to the Dutch market with a series of chairs and tables called "doe meer" (do more). They were manufactured in the Tan Sad factory in England, known for producing the first ergonomic chairs. In 1920, comfort was a significant luxury, and factory workers often sat on benches without backrests. The "Do More" chair was, therefore, far ahead of its time. As seen in advertisements from that era, it promised workers: "The ideal chair for the working person. For use in offices, drafting rooms, laboratories, for operating office machines and telephones, etc. The right support for your work." Due to its specially designed frame – the seat is adjustable in height, and the backrest can be adjusted in height and angle – it is a chair on which you can sit for hours without any issues, while also encouraging proper posture. Dimensions: 82 x 54 x 46 cm Weight: 9.2 kg The chair is in good condition, and although it could be reupholstered, the original cover adds to its sentimental value.
