Keilhauer, 2006

Squig focuses on researched principles of (gender-based) differences in sitting. Pelvic Balance Point technology compensates for individual sitting balance and center of mass, which is directly related to physical differences between genders; and the Free Shoulders design

completely supports the spine while allowing the shoulders and upper body to move freely.
The science involved in creating this chair results in a product that supports increased user alertness and concentration while addressing the causes of seating-related muscle pain.
