Berlage was a man who did not like curves. Because a chair needs a back that reclines a bit to make it more comfortable to sit on, he applied another design principle, according to reviewers of his work borrowed from the Egyptian Chair: Not having the back and the hind legs of the chair being made from one curving piece of wood, but to have the back lean on the seating or, like in this chair on the ruler connecting hind legs and front legs. Frank Lloyd Wright, who inspired Berlage did the same with this high back chair.
