What is the meaning of this with regards to a bicycle saddle?

Pressure = pain causing magnitude, which should be as small as possible
Force = magnitude determined by body mass and gravitational acceleration
Area = useable surface area of the saddle and cyclist

The larger the area, the lower the pressure.This physics law implies an advantage for the SQlab step saddle concept. The area does not - like with other ergonomic saddles - need to be reduced in a contra-productive manner with holes and cut-outs.
