Another seating question for comfort? health

[Sdspeed]

I'm gonna pull the trigger on a a used yak tomorrow. If I don't I'll analyze it to death. I have low back and leg issues (pain). With all the seats out there has anybody with pain issues found some relief with a seat bottom that is thicker. Have to paddle , I do know that, so no peddler for me.

I've seen some anywhere from 1" to 3 " thicker than most stock seats.
Not only more padding on my boney but will the angle possible help with health issues. I know this is subjective but thought someone with leg or back issues may have an approach without buying 20 different seats.

I honestly think I'll feel better if I get involved and take a chance of improving my health than if I just sit here staring at my computer screen.

thx
