A Bentwood chair is sometimes called a Thonet Chair in honor of its creator, Michael Thonet. While bentwood chair were actually being made at least two centuries before Thonet was even born, he perfected the process of steam bending.

 

THE DISCOVER

After years of bending laminated wood, he discovered that by attaching a metal strip along its length, solid wood could be bent in a similar way.

Wood bending process.

Thonet’s essential breakthrough was his success in having light, strong wood bent into curved, graceful shapes by forming the wood in hot steam.

This eliminated the costly lamination process and earned patents guaranteeing a virtual monopoly on production, enable him to design a lightweight, durable and comfortable furniture, which  aesthetic and functional appeal remains to this day.
