A good sprung saddle like Brooks Flyer has hard springs. So it doesn't bounce when pedalling, but when you hit a bump you didn't notice, instead of getting a bolt into your spine, the spring softens it up. Just those big hard bumps that come unnoticed.

I used it as a good addition to decently fat tyres on my relatively upright sitting city commuter.
