Ergonomics

For someone seated, the 'buttock popliteal' length is the horizontal distance from the rearmost part of the buttocks to the back of the lower leg. This anthropometric measurement is used to determine seat depth. Mass-produced chairs typically use a depth of 15 to 16 inches (38.1 to 40.6 cm).
