A spring support the car weight flexibly usually called suspension, i.e. the car is suspended on springs...
but springs tend to oscillate to and fro continuously making the ride bumpy, i.e. if you cross one bump, you car will keep on bumping for a while.
To control this bumping, a damper or shock absorber is used. It will damp out the bumping quickly enough.
So please elaborate your un-comfort? how you feel on bumps?
