Bentwood chair. In the middle of the XIX century in Europe Michael Thonet opened a factory for the production of bentwood furniture, the so-called Bentwood furniture. By 1850, he created the first chair entirely of curved elements. The basic material was selected beech. The combination of a very simple but light and robust design and low price these products gave immense popularity. Durability Bentwood chair was once demonstrated spectacular publicity stunt: he was thrown from the Eiffel Tower and did not crash! Not one thing traditional furniture would not survive such a test.
