How to get stiffness and damping values for single degree of freedom?

I'm doing mathematical modeling for (SDOF) a car seat which has mass 20 kg. I need stiffness and damping values to solve the equation of motion in Matlab. So please can u tell me any procedure to get these value.

There is a relation between natural frequency, stiffness and mass.....the relation is :
w = sqrt(k/m) ;
As you want to find what should be k...then you have to decide/ fix frequency w and then get k, as m is known.
YOu can have a look on Rayleigh damping, to fix the take damping value. Rayleigh damping depends on K and M.
