To create a chair that takes into account the needs of almost every person, HARAchair conducted 10 years of research. It turned out that the pelvic bones in men and women have different angles (65 degrees for men and 85 degrees for women), and the height and weight of a person play a huge role in the kind of support they require from a chair. While sitting on a chair, the weight of the upper half of the body puts pressure on the pelvis and surrounding tissues, with only 8% of the body’s surface area bearing all that pressure against the seat. Therefore, the pelvis needs effective support.
