Initially, I attempted to make a bentwood chair using door skins and a mold. However, I think the radius of the curve was too small and even after wetting the wood and steaming it with a tea kettle, it broke.
For the last part I had to glue the tops and the sides together. I did this using a glue gun
For my 1:1 model, I decided to make it out of chipboard. First I measured and drew out the side views of the chair with a ruler and compass. Then I cut them out. Next I cut out the sections I would use for the top view. To get them to bend, I kerfed them and kept them in the desired shape with wood glue pressed against a box to dry.
